  • Fixed HomePlug settings page table headers (broke in v2.16.2)

v2.16.4 (Aug. 2, 2016)

eGauge Systems LLC (eGauge) has determined that devices with serial numbers of the form:

  • 1504xxxxxx
  • 1505xxxxxx
  • 1507xxxxxx
  • 1508xxxxxx
  • 1509​​xxxxxx

as shipped may not be able to operate over the full temperature range (-30 to 70 degrees celsius, -22 to 158 F). In particular, if these devices operate at an internal temperature significantly over 50 degrees celsius (as reported by the Device Status page), they are likely to experience corruptions that can lead to the device becoming inoperable or unable to record any new data.

eGauge has developed a firmware fix for this issue that fully restores the affected devices to being able to operate over the entire temperature range. eGauge therefore recommends upgrading affected devices to firmware version 2.16.4 at the earliest convenience. It is recommend to perform the firmware upgrade when the internal device temperature is below 55 C (as reported on the device status page) and to reboot/power-cycle the device first to confirm that it’s still working fine. To protect the integrity of already deployed devices, eGauge will proactively upgrade the firmware on affected devices that are accessible via the Internet.

Where to find the serial number of a device:

  • Label on the bottom of the device.
  • Device Status page (View -> Device Status).
  • Certificate of Calibration.
  • Installation information sheet from the device sleeve.

If you can’t locate the serial number of a device, please feel free to contact support@egauge.net and provide the device name (for example, “eGauge123456”).

  • In Settings→Access Control, the user can no longer delete the user they are authenticating under, preventing them from locking out their access to the device.
  • Correct definition of VAr() function.
  • In Settings→Installation, properly preserve custom scale factors for self-powered rope CTs.
  • Fix bug that caused push service to try to connect to server more than once a second.
  • Fix avg() function to work properly even when the averaging interval extends beyond the “epoch” (time when recording started).
  • Fix bug that caused custom time-zones not to be saved properly.

v1.12.2Bug Fixes:

  • Fix a glitch that could cause random failures in sending SMS messages, particularly to AT&T phones.

v1.12.1New Features:

v1.12 (April 5, 2012)New Features:

  • The graph legend now has a toggle all/none button at the end, to make it easy to display all or no registers
  • New register-list selection editor in Preferences editor. This one makes it much easier to see what register have been selected and to add/remove registers
  • Added 60A and 1200A CTs.
  • Added “robots.txt” to keep robots web crawlers from indexing device pages
  • New PV_est() function to make it easy to raise an alert if actual PV production is below monthly estimates based on PVWatts or similar models
  • The XML API has been extended to allow passing an empty “Z” parameter. This has the effect that time-stamps in CSV-formatted output will be converted to the device-local time, as specified by Settings→Date & Time→Time Zone

Bug Fixes:

  • Fix a bug that could cause previously unused voltage channels to read around 500V, no matter what the input voltage was.
  • Fix a bug that could prevent saving the settings page when the PT settings had non-default values.
  • Fix a bug that caused time strings to be misread when the seconds where specified (along with hour and minutes).
  • Disallow register names starting with a dot or containing commas.
  • Fix a bug where a remoted eGauge connected via TCP would sometimes fail to re-establish the connection after a temporary outage.
  • Work around an issue that prevented alerts from being sent through comcast.net
  • Fix bug that caused nothing to displayed when clicking on month/year data in the “Monthly Summary” page.
  • Fix a bug where bogus lines could appear on a graph after, e.g., clicking on a month in the Monthly Summary and then resizing the resulting window.
  • Fixed a bug on the Alerts page that caused errors with Internet Explorer.
  • Fixed time setting when backup battery has been depleted.
  • After setting a new date and time, the device needs to reboot now.

v1.11 (April 12, 2012)Bug Fixes:

  • Fix a bug which made it impossible to save the alert settings unless the alert destinations and the user-defined alert patterns had at least one entry
  • Fix a bug which could cause data from remote devices to be ignored. This could be triggered by moving time back or if, for some reason, a bogus timestamp was received/stored for a remote device
  • Fix a bug which could cause the device to reboot when the status of the proxy-server connection changed
  • Fix a bug where register values could accidentally be reset to 0 if the device was power-cycled at an inopportune time. In particular, there was a good chance of this bug getting triggered when the device was reset by the watchdog handler
  • In email and SMS alerts, indicate how long ago the alert was triggered. This reduces confusion when an alert cannot be reported immediately (e.g., because there are other higher-priority alerts pending already)
  • Fix a bug which could cause no data to be returned when fetching the data for epoch (time when recording started)
  • On Mac computers, you can now use the ? (Command) key instead of the Control key to display the graph pop-up info. The Control key does not work well on Mac since pressing it along with the mouse key brings up other dialogs
  • On the “Month-by-Month Summary” page, fix a bug which caused no graph to be displayed when clicking on any of the numbers in the tables for “Total Energy Generated”, “Total Energy Used”, or “Net Energy Used”
  • In the “Export data to spreadsheet” dialog, rename “Average Power” to “Average Value” and “Energy” to Cumulative Value” since not all exported values are necessarily energy values anymore

v1.1 (April 1, 2012)New Features:

  • Multi-user support: It is now possible to define additional users via Settings→Access Control. This dialog replaces the more limited Settings→Password dialog. For each user, one of several access-rights modes can be selected. When site-wide password protection is enabled, a user can be restricted to seeing the view whose name is given by the username. This can be used, for example, to restrict a condo owner to see only the energy data for his/her own condo.
  • Device alerts: eGauge now supports predefined system-alerts and user-defined alerts. Alerts can be reported via email or SMS to a phone. Use Settings→Alerts to setup alerts and View→Alerts to view/clear pending alerts.
  • SMANet support: SMANet-capable devices such as SMA SunnyBoy inverters or SMA Sunny SensorBox weather-stations can now be read by eGauge with the help of a low-cost RS485-to-Ethernet adapter.
  • Improved PowerOne Aurora support: Reading out PowerOne Aurora inverters can now be done through the same infrastructure that was developed for SMANet. This greatly improves the reliability of reading the data and removes any limitation on the number of registers that can be read from the Aurora inverter.
  • Formula-register support: It is now possible to define registers whose value is given as an arbitrary function of other register values. This can be used, for example to record the power-factor (calculated from the measured real power and apparent power) or to record the predicted solar output as calculated from the irradiance and panel temperature measured by a weather station. See the eGauge Configuration Guide.
  • Internationalization infrastructure: An infrastructure is now in place for internationalizing the eGauge dash-board. A German version can be viewed by appending “?lang=de” to the device URI, a Traditional Chinese version can be viewed by appending “?lang=zh_CN“. The language-choice will be remembered by the browser until it is changed again. If you are interested in seeing other languages supported, please contact us.
  • Kiosk improvements: The traditional (“bunny”) Kiosk has been enhanced to display metric units for non-US language environments. A new kiosk-style called “Sleek Kiosk” has been added. The Kiosk-view can now be selected via the “View” menu in the dash-board.
  • User-selectable graph colors: The dash-board’s primary graph colors are now configurable to assist users for whom the default colors do not work well (e.g., due to color-blindness). See Settings→Preferences.
  • Improved Preferences editor: Register-lists can now be defined simply by clicking the desired registers rather than having to enter them manually. Colors can be selected from a pop-up color palette, and boolean values can entered simply by clicking a checkbox.
  • REC-payment support: A new preference-value has been added that can be used to define the renewable-energy-credit (REC) payment that is received per kWh produced. Where applicable, this can be used to more accurately calculate the money saved due to a renewable energy system. See Settings→Preferences.
  • NTP-server is now configurable: The NTP-server used to fetch atomic-clock accurate time can now be configured in the Settings->Date & Time dialog. The default server used is north-america.pool.ntp.org.
  • Device time zone support: The time zone that the device is installed in can now be configured via the Settings->Date & Time dialog. Note: The time zone is currently used only for internal calculations (e.g., to calculate the start of a billing period). The dash-board continues to use whatever time zone the browser is in.
  • Self-powered rope CT support: Self-powered rope CTs can now be configured in Settings→Installation by selecting “Rope 6"” from the CT drop-down menu and entering the value printed on the calibration sticker.

Bug Fixes:

  • For Opera browser, switch to using Canvas instead of SVG graphics because that works around a bug where Control-clicking with the mouse would zoom the SVG graph
  • Make the “Select view” dialog work on IE and Firefox for Windows
  • Improve the way data is caught up with for a remote device that was unreachable for some time. Specifically, the reported readings are now guaranteed to stay within 10% of the true reading while catching up with the remote device (and no error when there is no need to catch up, of course…)
  • Greatly reduce the likelihood of introducing spikes when changing the device configuration
  • The geo-coding service that was used for mapping an address to geographic coordinates no longer was operational. Switch to a different service
  • Fix bug that caused channel-checker not to work when a voltage or current was being recorded that wasn’t used for power calculations (e.g., when measuring DC battery voltage)
  • Fix cursor-tracking problem for Firefox browser
  • Improved legibility of times displayed in the graph. For example, instead of 3:00AM, the format 3am is now used
  • Improved iPhone and IE7-compatibility
  • Fix several memory-leaks caused by the push-URI feature
  • For non-default views, only display registers defined for that view
  • Fix bug that kept the dash-board graph from loading when setting a custom time-period to display for a second time
  • Fix bug which caused the “set custom time-range” dialog to leave open the hour-selection box when tabbing out of it
  • Improve proxy-client to automatically recover from network connectivity problems when DHCP name server list changes
  • Increase configuration-size limit to permit much bigger/complex device-configurations
  • Remove Google PowerMeter support/references, since it is no longer operational
  • Fix bug that could cause no data to be returned when fetching data near the epoch (time when recording started)
  • The XML format for instantaneous data now includes the same configuration serial number as the stored-data output
  • Fix bug where the “current” gauge would show up after resizing the browser-window even though it was not supposed to show


Maintenance release

v1.05Bug Fixes:

  • On devices with expanded memory, there was a corner case which could cause the device to reboot under certain circumstances
  • When renaming a register in Settings→Installation, the Totals and Virtual Registers using that register were incorrectly reset to the first register in the list

v1.04 (Nov. 1, 2011)Changes:

  • Increase limit that made it impossible to configure lots of registers with long names. This limitation only affected devices with expanded memory.

Bug Fixes:

  • Fix a buglet that caused IE9 to reboot a device only once, due to aggressive caching.
  • Fix a bug that caused the data of subtype registers (e.g., positive-only registers) to be corrupted when adding any other register.

v1.03 (Sept. 29, 2011)Bug Fixes:

  • Fix mishandling of remote devices that have no registers

v1.02 (Sept. 19, 2011)Changes:

  • Tweak scaling policy to make the new dashboard work better on low-resolution wide-screen computers (like netbooks). Specifically, instead of scaling the dashboard to always fit the width of the screen, it now fills the screen to fit the entire graph and (some of) the legend

v1.01 (Aug. 30, 2011)Bug Fixes:

  • Fix a buglet that caused the Settings→HomePlug screen not to work properly.

v1.00 (Aug. 1, 2011)New Features:

  • Updated Look The updated look provides an indication of which power- and time-zoom level has been selected, among many other things. All graph-specific operations are now grouped into a single graph-menu in the top-left corner of the graph, replacing the “→CSV” button. Specifically, this menu allows to set the date range to be displayed in the graph, export to a spreadsheet program, and select a non-default view.
  • Default settings for graph It is now possible to customize the default time-zoom and power-zoom used when loading the graph on the main page. This can be done via Settings→Preferences and also through query paramters (“t” sets the time-zoom in minutes, “p” the power-zoom in Watts). It’s now also possible to specify additional registers that should be displayed by default in the graph. The register-list to be displayed can be passed via query-parameter “r”, or can be set via the corresponding Preference entry.
  • Data Summary in Graph When pressing the Control key while moving the mouse pointer over the graph or “Current” gauge, eGauge now displays a summary of all registers for the point under the mouse. Also, when dragging an area of the graph while pressing the Control key, eGauge will highlight the dragged area. Upon releasing the mouse button, a popup-window is displayed that gives a summary of the data for the dragged area.
  • Time-navigation buttons There are now four clickable buttons below the graph which allow to navigate through the recorded data page by page, move to the very beginning of recorded data, or move the to the very end of recorded data.
  • Site Password It is now possible to establish a site-password (Settings→Password). With a site-password, any access to the device will require authentication with username user and the established site-password (alternatively, you can also authenticate yourself with username owner and the owner-password). Devices which have a site-password established are not listed at http://www.egauge.net/devices/.
  • Remote Devices It is now possible to have eGauge read data from another device. At this time, data can be read from other eGauges, from Power-One Aurora inverters (via an Ethernet-to-RS485 adapter), and from the Alpha-Innotec Luxtronik 2 heat-pump controller. Support for other select devices will follow.
  • Recording of non-power data In addition to recording net real-power data, eGauge now also can record the following quantities:
    • Positive-only real power (+). Such registers will only advance when the measured power is positive
    • Negative-only real power (-). Such registers will only advance when the measured power is negative
    • Absolute value of real power (|). Such registers will advance both when the measured power is negative or positive (i.e., the direction in which the power flows is ignored)
    • Apparent power (*). Such registers record the absolute value of the apparent power (the product of the RMS voltage and RMS current)
    • Current (I) measured by any of the CTs
    • Voltage (V) measured at any of the voltage-taps (L1-L3)
    • Frequency (F) measured at any of the voltage-taps (L1-L3)

    For any of these quantities, eGauge records the average value for each interval. The eGauge main unit has space for up to 12 registers. As the device is being configured, the Settings→Installation page now displays how many registers are in use and how many are available for use.

  • Virtual Registers The “totaling” section in the Settings→Installation has been enhanced to allow for defining additional arbitrary virtual registers. A virtual register represents an arbitrary sum or difference of other (physical) registers.
  • Potential Transformers It is now possible to configure the voltage scaling factors of L1, L2, and L3. This is useful when the voltages at those pins have been transformed down with a potential transformer.
  • Hostname and DNS Masquerading When changing a hostname (Settings→Network Settings→Hostname), the new name is now also reflected in the DHCP table so that DHCP-based DNS maquerading will find the device under the new name.

  • Fix a bug that was introduced in 0.85 that kept a device from re-acquiring IP info via DHCP once it failed

v0.85.2New Features:

  • When viewing a register (not a total) in the “Stats” monthly statistics page, clicking on a number on that page now brings up a graph showing just that register


  • Make hourly and daily CSV exports work reliably and more intuitively


  • CSV exports are now done in the browser’s time-zone. This makes the date/time in a CSV file consistent with the date/time displayed in the browser’s graph, etc

v0.85New Features:

  • New Settings→Preferences dialog allows the setting of a descriptive page-title for the main page


  • Google Chrome browser now defaults to using Canvas rather than SVG to avoid rendering bugs in Chrome’s SVG implementation

Bug Fixes:

  • Fix a buglet that prevented the “Current” label from showing under the “currant usage/production” gauge
  • Fix a bug in the web-servers CGI-handler which had the effect that occasionally a CGI connection wasn’t closed properly, causing the client to hang

v0.84New Features:

  • Added basic support for BACnet/IP and BACnet/Ethernet


  • Revised the export CSV functionality to output average power by default (with an option to export energy readings, like before). Also replace “Use” and “Gen” formulas with computed values to avoid problems with different spreadsheets using different operand separators

Bug Fixes:

  • Fixed accidental reversal of the date and time fields in the Date and Time picker widget


  • Improve Google Power Meter handling of device de-activation and re-activation

Bug Fixes:

  • Fix a typo that caused an “Error on page” error when rebooting a device through Internet Explorer

v0.83.4New Features:

  • Add a means to the “Status” page to (securely) lookup the MAC address, which is needed for online warranty registration


  • In the calendar popups, the week now starts with Sunday, by popular request

Bug Fixes:

  • Fix typos on GPM page which caused Firefox to croak


  • Improve IE8 support a little. This makes, for example, GPM deactivation work without complaints

v0.83.1Bug Fixes:

  • Plug resource-leak in Google PowerMeter daemon

v0.83New Features:

  • Added Google PowerMeter support for eGauge2 hardware. Not available on eGauge1 hardware due to limited storage space


  • Properly report when setting the HomePlug encryption password fails
  • Properly handle empty (unknown) vendor names

v0.82New Features:

  • On Windows-based computers, it is now possible to access eGauge directly through its device name, without having to first install any additional software. For example, eGauge539 can now be accessed as http://egauge539/ as long as the device is in the same LAN-broadcast domain as the computer
  • Add HomePlug settings screen. This provides a means to see what the individual communication speeds to each HomePlug device are and to set a non-default encryption password. Please be sure to read the Help info on this topic before using this feature!
  • On model eGauge2 devices, the Status LED now alternates between green/magenta or blue/magenta if the device is configured to use DHCP but the device was unable to obtain DHCP information (such as an IP address). If unable to obtain the DHCP info, the device will blink green/magenta when the HomePlug link speed is above 2Mbps and blue/magenta otherwise

v0.81.1New Features:

  • Add the ability to install test-releases of the firmware

v0.81Bug Fixes:

  • Fix a bug that was introduced by the blinking Status LED which had the effect that the proxy-connection would go seemingly dead after the device ran for some time

v0.80New Features:

  • Android-based devices such as the Google Phone (gPhone) are now supported. To be precise, this release adds support for any browser that supports the canvaselement as defined by the HTML5 standard (including the text-method fillText). Browsers that also support SVG will continue to use SVG
  • The “Statistics” page (“Stats” link) can now display monthly summaries for any register, in addition to the summaries for the totals (Usage, Generation, and Net Usage)
  • The “Statistics” page (“Stats” link) has been enhanced such that clicking on any monthly value displays a usage/production graph for that month. Similarly, clicking on any annual value displays the usage/production graph for that year
  • The Status LED now blinks when the device is connected to the proxy-server. If the speed of the HomePlug-link is at least 5Mbps, the LED will blink green, otherwise it will blink blue
  • The reboot page has been enhanced such that it attempts to automatically detect when the device has come back from the reboot. The only time the automatic detection may not work is when the device’s IP address or name changes because the of the web-browser’s same-origin security policy
  • It is now possible to use arbitrary ASCII/UTF-8 symbols in register-names. Previously, using certain punctuation marks such as /-characters would cause problems


  • What used to be called “Source” in Settings→Installation is now called “Register”. The name “Source” was confusing when it was used for loads, such as pumps or ovens

Bug Fixes:

  • Added an Internet-Explorer workaround which has a bug that had the effect of creating pop-ups with the message “No XML elements”. This issue appears to be limited to IE8 as shipped on Windows 7 (IE release 8.0.7600.16385)

v0.79Bug Fixes:

  • This release fixes a bug where in certain environments, a temporary networking failure could lead to a device being unable to connect to the proxy-server (d.egauge.net) even after the networking failure was fixed

v0.78Bug Fixes:

  • The fix in v0.59 broke daylight-savings-time again. This should be fixed for good now and should work correctly for leap-seconds and daylight-savings time and whatever else you can throw at it…

v0.77Bug Fixes:

  • Fix a bug that could cause incorrect energy delta being displayed in the time range and/or the “Statistics” page. Oops.
  • Fix a misfeature which caused bogus data to be displayed on the “Statistics” page if the epoch was within the current year

v0.76New Features:

  • A password-reset feature has been added to the “Settings→Password” menu. When resetting the password, remote-administration will also be disabled, since it would be unsafe to allow remote administration with the default password
  • The “Upgrade” link has been replaced with a “Tools” menu. This menu provides access to a data backup and restore facility, a facility to zero out data-spikes. It also provides utilities to reboot the device, upgrade the firmware, and display istantaneous channel-, power-, and power-factor values
  • This release adds support for finding a a local eGauge device via mDNS. In practical terms, this means that you’ll be able to access your device with URL http://DEVNAME.local, where DEVNAME is the device-name, such as eGauge1. In other words: no need to remember or bookmark the IP address of the device anymore! This works out-of-the-box on Mac OS X and Linux machines. On Windows machines, it’s generally necessary to first download and install Bonjour for Windows. It’s a small (<3MiB) and painless install, so we recommend it
  • On eGauge2 hardware, settings can now be changed with username “owner”. The default-password for this username is “default”. The password can be changed through Settings→Password. On this tab, it is also possible to enable remote administration. Needless to say, remote-administration should be enabled only after changing the default-password to a strong and secret password

Bug Fixes:

  • A bug has been fixed which with certain inverters caused small power usage to appear as a small production
  • A bug has been fixed that prevented CSV-export to work on certain configurations
  • A work-around for Internet Explorer v8 (IE8) has been implemented which prevents errors when incomplete responses are received over the network

v0.75Bug Fixes:

  • The energy summary displayed after the “Time range” indicator used to show duplicate (and potentially) conflicting energy units such as “kWh kWh”. This bug has been fixed in this release

v0.74New Features:

  • The energy-data can now be exported to a spread-sheet program by clicking on the “→CSV” button in the top-left of the graph on the device’s home page
  • Date and time entry fields commonly used by users now pop up a calendar or hour-picker window, respectively, for simplified entry. Also, the time fields now accept time in 24-hour format (e.g., “18:00” instead of “6pm”)
  • The “Time zoom” list, now has additional entries for 6 months (6m), 3 months (3m), 3 weeks (3w), 2 weeks (2w), 6 hours (6h) and 3 hours (3h)
  • Input and select elements are now again rendered in the browser’s default-style

Bug Fixes:

  • On eGauge2 hardware, make DHCP lookup more reliable.Formerly, if the device was unable to obtain an IP address via DHCP, it would permanently fall back to, it will periodically retry to obtain a DHCP address, which is the Right Thing To Do and matches the behavior on the eGauge1 hardware

v0.73New Features:

  • On eGauge2 hardware, display the reason for the most recent reboot on the “Status” page
  • Add 150A CTs and tweak 50A CT in Settings→Installation

Bug Fixes:

  • On eGauge2 hardware, make DHCP lookup more reliable.Formerly, if the device was unable to obtain an IP address via DHCP, it would permanently fall back to, it will periodically retry to obtain a DHCP address, which is the Right Thing To Do and matches the behavior on the eGauge1 hardware

v0.72Bug Fixes:

  • Fix many Internet Explorer rendering issues
  • Correct some energy-calculations

v0.71Bug Fixes:

  • Fix a bug that could cause the “Totaling” formulas (Settings→Installation) to be wiped out when changing other settings
  • Fix LED handling so it switches back to blue if HomePlug speed drops below 5Mbps
  • Fix LED handling so overtemperature is displayed as blinking red


Internal release only

v0.69New Features:

  • The CT configuration is now completely web-configurable via Settings→Installation. This is not (yet) supported in Internet Explorer. Opera, Firefox, Safari, Google Chrome browsers all handle it fine. Take your pick
  • The date and time of the device can now be checked and, if necessary, changed via Settings→Date & Time

v0.68New Features:

  • Add support for measuring pure 208/240V inverters (or loads) with a single CT


  • Switch to using floating-point rather than fixed-point arithmetic.This used to be too slow in eGauge1, but with a little trick, it’s now fast enough on eGauge1 and actually 10% faster on eGauge2.A nice side-effect is that accuracy should improve significantly on installations with CTs with large current ratings (e.g., 600A)


This version was internal only and was never released

v0.66Bug Fixes:

  • A bug was fixed that caused artificial “ripples” in the power curves at intervals of about every 5-8 minutes
  • A bug was fixed that could cause incoherent data to be displayed in the “Current” gauge


  • The proxy-client now assumes the proxy-connection is dead if it hasn’t received anything from the server in the last 5 minutes. This should improve reliability of the proxy-connection

v0.64Bug Fixes:

  • Fix a bug in the Kiosk where the rabbit/snail speed of usage and generation was flipped

v0.63New Features:

  • Update Kiosk to use mapping formulas, like the other web pages

v0.62New Features:

  • The “Stats” page now displays the HomePlug transmit speed

Bug Fixes:

  • Fix a bug that could cause the red LED to stay on permanently even after an overtemperature situation has been resolved

v0.61Bug Fixes:

  • Fix handling of negative temperatures in the “Stats” page
  • In “Settings→General Settings→address lookup”, use batchgeocode.com instead of maporama.com to translate an address to latitude/longitude coordinates.The latter doesn’t seem to work anymore

v0.60Bug Fixes:

  • Make “Stats” link work again by distributing Int64.cjs as a stand-alone file (rather than as part of EGauge.cjs)

v0.59New Features:

  • The formulas used to map the individual power components to total usage/generation figures is now configurable in the “Settings” menu (“Mapping formula 1/2”).Read the Help page for details on the format of these formulas

Bug Fixes:

  • The daylight-savings-time fix from Nov 2nd (v0.56) broke some of the time labels.For example, when displaying 31 days worth of data in the graph, the day-of-month labels were missing.This has been fixed now (while still keeping the DST-switch fix in place)
  • On Internet Explorer, selecting a time-zoom of 31 days now properly displays the day-of-month labels (this has been working all along with other browsers, such as Firefox).
  • Fix bugs that showed up when fetching data that crosses a resolution-boundary (affects eGauges with at least 1 year worth of data; note that the data is recorded properly, the bugs affected only the display/rendering of the data)

v0.58Bug Fixes:

  • Fix some Opera and Safari rendering issues on the “Stats” page. Also, work around IE7 issues which caused it to fail on this page. The page still doesn’t look good on IE7, but at least it displays the data properly

v0.57New Features:

  • Added a basic statistics page which summarizes monthly and annual production, generation, and net-usage.This page is reached by clicking on the “Stats” link in the menu on the top right of the eGauge web pages

Bug Fixes:

  • Fix a bug in the Int64.js package which under certain circumstances caused a 64-bit number to be mis-printed with missing zeroes

v0.56Bug Fixes:

  • Fix a bug that caused browsers to get “stuck” when trying to display a graph that crossed the time of switching from daylight-savings-time to standard time


Bug Fixes:

  • Fix an SVG-rendering bug which caused the shaded areas to be displayed incorrectly with the Google Chrome browser

v0.54Bug Fixes:

  • After hitting the “Save” button in the settings dialog, the response popup is being displayed again

v0.53Bug Fixes:

  • Make “subpanel” sources work correctly again

v0.52New Features:

  • Added a watch-dog facility. Once in a blue moon, eGauge appears to get “stuck” in a way where it’s possible to ping the device, but nothing else works. Until we can track down and fix the root-cause, the watch-dog is intended to work around this problem by rebooting the device within 30 seconds after the situation arises. Such automatic reboots can be detected after the fact by clicking on the “Status” link. If the date shown there for “Last web-initiated reboot” does not match with the date displayed in “Uptime”, then a reboot may have been triggered by the watch-dog or a power failure

v0.51Bug Fixes:

  • Fix bug that caused LED-polarity to be dropped when making any configuration-changes via the web-interface

v0.5New Features:

  • The eGauge main page now loads faster, thanks to a more compact encoding of the energy-data
  • The “Time range” is now followed by energy information. Specifically, the information consists of the amount of energy produced during the displayed time-range (red), the amount of energy used (green) and the net energy used (black).This makes it easy to cross-check eGauge measurements with, e.g., utility bill
  • It is now possible to display the individual power sources and loads being measured.The display of particular source or load is enabled in the “Legend” by clicking the checkbox in front of that soruce or load.This allows, for example, to see how much power a solar system is using during the night (to see this curve, you may need to select a “Power zoom” level of 50W or so)
  • The “Status” page now displays the revision of the installed software and how long the device has been running

Bug Fixes:

  • The power auto-scaling should now work much more reliably and will now also ensure that the “Current” power display is within the range of the power scale
  • The “Settings” now work on Internet Explorer
