V2 Firmware History:
- Added check for Enphase Envoy and to retrieve power values for Enphase if found.
- E or e toggles Enphase search and data retrieval.
- Revised to use EITHER HEATENABLE or CHARGENABLE for frequency shift.
- If CUTOFF=RESUME use charge enable
- If HITEMP=LOTEMP use the HEATENABLE.
- If neither are equality they operate normally.
- Major upgrade adding a clock scheduler for AC grid input control
- Fixed bug bricking device if settings.parallel=0.
- Also attempt connecting to wifi again if first attempt fails.
- Added preliminary code to support ShellyEM device
- Tweaked balancing a bit.
- Constrain SOC to between 0 and 100
- Added code to auto reset serial to Tesla modules if there are comm errors for too long.
- Show good/bad packets for each module
- Add additional mode to toggle module ground with heat enable pin
- Added an additional mode (on by default) that will try to freq. shift then open the contactors if the comm to modules is faulty.
- This will then be reverted and the contactors closed again if communications come back.
- Added ability to send UDP frames to a remote host for capture of logging to a persistent place.
- Added ability to wirelessly connect with extension boards that are themselves connected to actual modules
- Fixed extension code
- Make S reset extensions too (they’ll automatically come back)
- Fixed some additional oddities with extensions
- Added a setting to expect extensions and fault if they don’t appear.
- Added ability to use a full TeslaBMS system as an extension to another full system.
- This allows redundant contactors, etc but unified display
- Changed the way SOC works quite drastically.
- Now the top and bottom 20% are based on voltage instead of current.
- It also updates the AH setting to match which helps to reset the current accumulation to match the actual pack.
- Added additional debugging output that can be picked up by the RPi units.
- Added an SOC drifting function which will slowly drift SOC to the proper value when the charge gets to the knees of the charge curve.
- This can help to cover up current drifting and pack capacity mismatch.
- Force CHARGE Enable to LOW any time the freq cycling routine is run.
- This is run just before the contactors are opened which also has the pleasant side effect of turning charging off at the same time.
- Fixed up variance fault detection (along with better status output when it happens)
- Try to better reset things when the extension system is turned off.
- Also a few tweaks to pack voltage calcs.
- Added ability to fake having modules connected (for testing purposes)
- Bug fixes
- Added header showing whether this system is the main or an extension
- Added more debugging stuff that can be displayed on the GTK app
- Added ability to directly send MQTT from this board.
- This allows a system without relying on the RaspberryPi.
- Fixed current blanking glitch
- Added output to show when current sensor is not responding
- Added a check for bad_alloc in UDP code that will hopefully prevent random reboots.
- Fixed a monitoring issue that could happen after 49 days of continuous uptime.
- Added additional checks for module comm to be extra sure that things are still working.
- Lengthened time required for module timeout from 10 to 20 seconds.
- Changed wifi init to be asynchronous and instead check periodically.
- Now there is no waiting when trying to connect to wifi.
- More debugging output (shown on Raspberry Pi app)
- Added a new supported board (ESP32-S3 version)
- Added webpage hosting to be able to view stats from any PC, tablet, etc.
- (In webbrowser go to teslabms.local)
- Added telnet capability to be able to get text console over the network
- (also teslabms.local)
- Better cell balancing
- Added an output of the reason contactors were opened
- (viewable in debugging screen of Raspberry Pi app)
- Added the ability to set a static IP address instead of requiring a DHCP server.
Raspberry Pi Display Version History:
- Added functionality to support use of the display with our Model 3 full battery controller.
- Display voltage and temperature alarms directly on the main screen
- Fix power log so it uses the set charge and discharge ranges
- Added the ability to use any MQTT server, not just Amazon.
- Added a debugging screen to assist in diagnosis.
- Many useful technical values are found here.
- Behind the scenes clean up
- Fixed a mistake in debugging data display.
- Allow for resolution scaling when used without the normal display
- Changed the background image
- Fixed up some display glitches
- Fixed up a lockup possible when doing DNS look ups
- Added ability to directly attach USB from the V2 to the Rpi4
- Added more accurate voltage and current display.
- Added more debugging info to the debug screen
- More debugging
- Addition of reason why contactors last opened
- Added CPU0/1 reason for reset.
- This allows for tracking why the reboot occurred.
- Implemented log file rotation.
- Previously log files could get excessively large.
- Made log file loading faster by only loading necessary data.
- Fixed potential lockup that could happen when displaying zero power
- Fixed direct USB connection
- Moved display of average voltage up a little and added more explanation about what it shows.
- Moved fault display and made it MUCH larger.
- This will make it very clear when a fault happens.
- No longer close the app when resetting the log file
- Made the background image a lot darker to increase visibility
- Changed text sizes and colors for better visibility.
- Fixed a crash that could happen in configuration screens
- Added the ability to turn the cursor on/off.
