- Improve loading of web pages with lots of data over slow network links. Previously, the loading may have timed out repeatedly without ever loading completely
- Fix NTP setup on model EG30xx devices so that they properly sync time with NTP servers again
- No longer get stuck for extended periods of time in the event that time moves backwards. This normally doesn't happen, but can occur when time is (manually) set to a date in the future and then that wrong date gets corrected
- "Generation" and "Usage" are reserved names and no longer allowed in physical registers
- Dots (".") are reserved characters to denote views in virtual registers and are no longer allowed in physical registers. Multiple dots are not allowed in virtual register names
- The entry for a "250A" CT in Settings→Installation has been changed to "250A rope" to clearly identify the entry for the previously stocked Magnelab RCT-1800. There is no implemented non-flexible 250A CT at this time
- Alert entry tables in Settings→Alerts now size correctly across browsers
(May 20, 2013)
- Existing rope and DC CTs now show properly again in the Settings→Installation menu
(May 14, 2013)

(Nov. 19, 2012)
- Custom line-styles can now be defined through Settings→Preferences.
- The device now stores up to 10 minutes of the most recent second-by-second data in volatile memory.
- The 60s (60 seconds) time-zoom button has been replaced by a 10m (10 minutes) button.
- Selecting a different time-zoom no longer resets the graph to the most recent time. To display the most recent time range, click on the (forward to current time) button at the bottom-right of the graph.
- The time-scrolling buttons at the bottom of the graph are no longer displayed if the graph cannot be scrolled any further in that particular direction.
- In the "Sleek Kiosk", a user-preference now controls whether or not the installer's logo is displayed in the upper-left corner of the display.
- The "Sleek Kiosk" has been updated to use the latest energy-conversion data from the EPA as of Oct 15, 2012.
- Temperature @lert WiFi Edition sensors can now be added as remote devices.

- Basic HTTP authentication is now supported for the push service (recommended over HTTPS connections only).
- Added physical units for measuring reactive power and relative humidity.
- Increased fraction precision for monetary units to 29 bits so kWh costs can be tracked with cent precision down to 1Ws.
- Data acquired by an eGauge from remote devices is now re-exported by the eGauge. For example, if an eGauge is reading a remote temperature sensor, that temperature data can then be read out by other eGauges.

(April 5, 2012)
- 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
- 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

- 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.
(April 12, 2012)
- 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
(April 1, 2012)
- 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
- 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
- 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
- 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
- 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.
- 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
- 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

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

- Fix several memory-leaks caused by the push-URI feature
- For non-default views, only display registers defined for
- 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
- Increase configuration-size limit to permit much bigger/complex
- Remove Google PowerMeter support/references, since it is no longer
- 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
- On devices with expanded memory, there was a corner
case which could cause the device to reboot under certain
- 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
(Nov. 1, 2011)
- Increase limit that made it impossible to configure lots of
registers with long names. This limitation only affected devices
with expanded memory.
- 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.
(Sept. 29, 2011)
- Fix mishandling of remote devices that have no registers
(Sept. 19, 2011)
- 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
(Aug. 30, 2011)
- Fix a buglet that caused the
Settings→HomePlug screen not to work properly.
(Aug. 1, 2011)
- 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
- Recording of non-power data In addition
to recording net real-power data, eGauge now also can
record the following quantities:
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.
- 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
- 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
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
the new name is now also reflected in the DHCP table so that
DHCP-based DNS maquerading will find the device under the new
- Fix slow rendering of partially invisible dashed line on
browsers using HTML5 Canvas for graphics (e.g., Chrome)

- Fix a bug that was introduced in 0.85 that kept a device from re-acquiring IP info via DHCP once it failed
- 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
- 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
- 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
- Make the background color of the Kiosk body white (rather than undefined)

- Plug resource-leak in Google PowerMeter daemon
- 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
- 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
- Add the ability to install test-releases of the firmware
- 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
- 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 canvas element 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
- 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)
- 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
- 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...
- 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
- 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
- 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
- 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
- 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
- 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 192.168.1.88.Now, it will periodically retry to obtain a DHCP address, which is the Right Thing To Do and matches the behavior on the eGauge1 hardware
- 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
- 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 192.168.1.88.Now, it will periodically retry to obtain a DHCP address, which is the Right Thing To Do and matches the behavior on the eGauge1 hardware
- Fix many Internet Explorer rendering issues
- Correct some energy-calculations
- 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
- 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
- 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
- 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
- Fix a bug in the Kiosk where the rabbit/snail speed of usage and generation was flipped
- Update Kiosk to use mapping formulas, like the other web pages
- The "Stats" page now displays the HomePlug transmit speed
- Fix a bug that could cause the red LED to stay on permanently even after an overtemperature situation has been resolved
- 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
- Make "Stats" link work again by distributing Int64.cjs as a stand-alone file (rather than as part of EGauge.cjs)
- 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
- 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)
- 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
- 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
- Fix a bug in the Int64.js package which under certain circumstances caused a 64-bit number to be mis-printed with missing zeroes
- 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
- Fix an SVG-rendering bug which caused the shaded areas to be displayed incorrectly with the Google Chrome browser
- After hitting the "Save" button in the settings dialog, the response popup is being displayed again
- Make "subpanel" sources work correctly again
- 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
- Fix bug that caused LED-polarity to be dropped when making any configuration-changes via the web-interface
- 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
- 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
