eGauge Firmware Release Notes
- v1.05.2
-
- v1.05
-
- 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. This bug has
been fixed.
- On devices with expanded memory, there was a corner
case which could cause the device to reboot under certain
circumstances. This bug has been fixed.
- v1.04
-
- 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.
- v1.03
-
- Fix mishandling of remote devices that have no registers.
- v1.02
-
- 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
-
- Fix a buglet that caused the
Settings→HomePlug screen not to work properly.
- v1.00
-
- 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.
- v0.86.2
-
- Fix slow rendering of partially invisible dashed line on
browsers using HTML5 Canvas for graphics (e.g., Chrome).
- Fix channel checker to allow displaying of more than 12
power components.
- v0.86.1
-
- Reset HomePlug chip once every 24 hours to guard against
potential connectivity-loss.
- v0.86
-
- Add IE9 support.
- Minor skin updates.
- v0.85.9
-
- Fix "Hour" vs "Hours" typo in Kiosk page.
- Minor skin update.
- v0.85.8
-
- v0.85.7
-
- Minor tweak: rename "Trees planted" to "Trees grown" on
Lightgauge skin.
- v0.85.6
-
- Added 15A CT.
- Added new skin.
- v0.85.5
-
- Fix a bug that caused display_history.html not to display
anything unless a "reg=" query parameter was specified.
- v0.85.4
-
- Fix a bug that was introduced in 0.85 that kept a device
from re-acquiring IP info via DHCP once it failed.
- v0.85.2
-
- Make hourly and daily CSV exports work reliably and
more intuitively.
- 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.
- v0.85.1
-
- 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.
- v0.85
-
- Fix a buglet that prevented the "Current" label from showing
under the "currange usage/production" gauge.
- 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 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.
- v0.84.7
-
- Add support for 1000A CT.
- v0.84.6
-
- Make the background color of the Kiosk body white (rather
than undefined).
- v0.84.5
-
- Tweak Kiosk to make it adjust to any screen size.
- v0.84.4
-
- v0.84.3
-
- On eGauge2 hardware, enabled ECC correction in the primary
bootstrap loader.
- The "Status" page now displays the hardware model and the
kernel version.
- v0.84.2
-
- Add support for 5A and 20A CTs.
- v0.84.1
-
- Fix a bug that caused the channel-checker not to display the
currents and voltages.
- v0.84
-
- 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.
- Fixed accidental reversal of the date and time fields in the
Date and Time picker widget.
- v0.83.5
-
- Fix a typo that caused an "Error on page" error when rebooting
a device through Internet Explorer.
- Improve Google Power Meter handling of device de-activation
and re-activation.
- v0.83.4
-
- Add a means to the "Status" page to (securely) lookup the
MAC address, which is needed for online warranty registration.
- v0.83.3
-
- Fix typos on GPM page which caused Firefox to croak.
- In the calendar popups, the week now starts with Sunday,
by popular request.
- v0.83.2
- Bug fix:
- Improve IE8 support a little. This makes, for example,
GPM deactivation work without complaints.
- v0.83.1
- Bug fix:
- Plug resource-leak in Google PowerMeter daemon.
- v0.83
- New features:
- Added Google PowerMeter support for eGauge2 hardware. Not
available on eGauge1 hardware due to limited storage space.
- v0.82.1
- Bug fixes:
- Properly report when setting the HomePlug
encryption password fails.
- Properly handle empty (unknown) vendor names.
- v0.82
- Improvements:
- 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.
- v0.81.1
- Improvement:
- Add the ability to install test-releases of the firmware.
- v0.81
- Bug fix:
- 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.
- v0.80
- Improvements:
- 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).
- 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.
- 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.
- 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.
- v0.79
- Bug fix:
- 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.
- v0.78
- Bug fix:
- 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...
- v0.77
- Bug 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.
- v0.76
- Improvements:
- 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 instantaneous 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.
- v0.75
- Bug 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.
- v0.74
- Improvements:
- 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 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.
- v0.73
- Improvements:
- 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 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.
- v0.72
- Bug fixes:
- Fix many Internet Explorer rendering issues.
- Correct some energy-calculations.
- v0.71
- Bug 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.
- v0.70
- Internal release only.
- v0.69
- Improvements:
- 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.
- v0.68
- Improvements:
- 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).
- Add support for measuring pure 208/240V inverters (or loads)
with a single CT.
- v0.67
- This version was internal only and was never released.
- v0.66
- Bug 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.
- v0.65
- New Features:
- 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.
- v0.64
- Bug fixes:
- Fix a bug in the Kiosk where the rabbit/snail speed of usage and
generation was flipped.
- v0.63
- Bug fixes:
- Update Kiosk to use mapping formulas, like the other web pages.
- v0.62
- New 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.
- v0.61
- Bug fix
- 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.
- v0.60
- Bug fix
- Make "Stats" link work again by distributing Int64.cjs as
a stand-alone file (rather than as part of EGauge.cjs).
- v0.59
- New feature:
- 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 fix
- 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).
- v0.58
- Bug fix
- 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.
- v0.57
- New feature:
- 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 fix
- Fix a bug in the Int64.js package which under certain
circumstances caused a 64-bit number to be mis-printed with
missing zeroes.
- v0.56
- Bug fix
- 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.
- v0.55
- Bug fix
- Fix an SVG-rendering bug which caused the shaded areas to be
displayed incorrectly with the Google Chrome browser.
- v0.54
- Bug fix
- After hitting the "Save" button in the settings dialog,
the response popup is being displayed again.
- v0.53
- Bug fix
- Make "subpanel" sources work correctly again.
- v0.52
- New feature:
- 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.
- v0.51
- Bug fix:
- Fix bug that caused LED-polarity to be dropped when making
any configuration-changes via the web-interface.
- v0.5
- New 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 bills.
- 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.
