If you find this useful please

Please do not post in this thread, it is for version release info, please create your own or use #1
Will try to keep this thread updated with latest version improvements.

You should ensure you are running the latest version of ESPHome upgrade by running "pip3 install -U esphome"

Test version for Pateron Alpha and Beta testers members.

• V 1.16
  Improved Alarm handling, all alarms will set change/discharge A to 0, set Charging status to Alarm
  Captive portal Wifi setup
  Web server for local management
  Fix inconsistent spaces (code improvement)
  Request force charge from mains if battery low, eg if no charge due to weather, snow etc.
  Added cycles offset and send correct charge cycles with offset to HA
  Send battery SOH to HA including cycles offset when calculating
  Add battery protocol selection type for pylon for better compatibility
  Stop sending CAN messages if no response (major improvement), code will detect when no inverter/not responding and stop sending CAN messages that resulted in WDT reboot issues. Code should now run without any issues if inverter is not connected.
  Deye inverter improvements for better support of this inverter.
  Fix daily reboot if HA is not connected.

Released versions:
Latest released version can be found here

• V1.13.3 14/5/23 Improve compatibility with Deye and other inverters

• V1.13.2 27/4/23 Send Max Temperature of T1, T2 to inverter

• V1.13.1 24/4/23 Fix compile issues with new version of ESPhome 2023.4.0, set rebulk offset to 2.5

• V1.13 11/2/23 Fix array too small

• V1.12 9/12/22 Fix discharge current

• V1.11 4/12/22
  Complete rework of the charging logic, now charges with constant current(CC) to the absorption voltage, then has an absorption timer (Constant Voltage, user configurable time), with rebulk feature (user configurable offset from absorption voltage).
  Live sliders for absorption voltage and charging current (can change on the fly!)
  Charging status user feedback to let you know what the charging logic is doing. Bulk, Absorption, Complete, Wait , Disabled, etc
  Reworked the Charge/Discharge controls and logic, so more user friendly (default to on as below).

• V1.05 30/10/22 Fixed alarms

• V1.04 20/10/22
  Added logic for calculating SOH, is now based on number of cycles/max_cycles.
  Added CAN messages 0x70, 0x371 cell temp and voltage info

• V1.03 16/10/22
  Charging logic added, will now charge battery to a set max_soc if soc drops below rebulk_soc will charge back up to max_soc. This should resolve issue with the inverter floating battery all day at the charge voltage.
  Added Home Assistant control switch "Inverter Charger ON (top bal)" to override the Charging logic, it will charge up to the set charging voltage, useful for top balancing. But you have to remember to turn it off!

• V1.02 13/10/22
  Added Home Assistant control switches to tells the inverter to disable charging and/or discharge.
  Allow control of the inverter charging and discharging from anywhere with internet, great for when you are out and need control!

Known issues: None at this stage

I'm using this version in my production environment which consists of:

• Goodwe GW5000S-BP inverter
• Goodwe GM3000 3 phase Smart meter cabled back to inverter (you can also use the GM1000 if you have single phase)
• 16 * EVE LF280K batteries in series for nominal 51.2v
• JK-BMS 150A model JK-B2A24S15P
• My Hardware Interface kit (plug and play just add power via USB)
• Various safety devices: Fuse and ZJ Beny125A DC circuit breaker etc.

Optional, to extend the distance from the BMS to Interface kit:

• JK RS485 module (you don't need this if your ESP32 is near the JK-BMS)
• RS485 to TTL module (you don't need this if your ESP32 is near the JK-BMS)
