Add Solax X1 Mini G3 support

[neujbit]

i have a problem with the Solax x1 mini G3 with following errors [07:18:49][W][solax_x1:083]: Invalid response size: 56 [07:18:49][W][solax_x1:085]: Your device is probably not supported. Please create an issue here: https://github.com/syssi/esphome-modbus-solax-x1/issues [07:18:49][W][solax_x1:087]: Please provide the following status response data: 00.17.00.00.03.DE.00.00.00.08.00.00.00.05.09.06.13.85.00.48.FF.FF.00.00.00.28.00.00.00.0C.00.02.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.01.00.8A.00.DE (56)

I will try to decode the data later the day and will provide some feedback your device can be easily supported or not.

Your device can be supported easily. I will prepare a pull request now:

[syssi]

Could you provide the exact model name and firmware version numbers of your device? I would like to add something like this to the lst of supported devices:

SolaX X1 Mini X1-2.0-S-D(L) (master version 1.08, manager version 1.07)

[syssi]

Next wish: Could you increase the log level of your ESPHome node to VERY_VERBOSE and provide a complete status response of your device? The log message should start with RX:

[15:42:33][VV][modbus_solax:083]: RX <- AA.55.00.0A.01.00.11.82.32.00.21.00.02.07.DB.00.00.00.1D.00.00.00.18.09.56.13.81.02.2C.FF.FF.00.00.5D.AF.00.00.10.50.00.02.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.07.96 (61)

And should be 67 bytes long in your case.

Please change the external_components source to:

external_components:
  - source: github://syssi/esphome-modbus-solax-x1@add-x1-mini-g3-support
    refresh: 0s

reflash your device and give it a try!

Perfect! I will merge the feature branch to main in a few seconds. Please change your external_components source back to main.
