This

RX <- 00.21.00.02.07.EF.00.00.00.1D.00 (11)

looks like an incomplete frame. If you compare the payload with the long (61 byte) frames starting with the header 0xAA 0x55 you can find similar values:

AA.55.00.0A.01.00.11.82.32.00.21.00.02.07.EC.00.00.00.1D.00.00.00.18.09.55.13.80.02.2B.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.A4 (61)
                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It looks like the payload has changed a bit. I will try to compare the old status report payload with your payload.

Please update your configuration yaml to

external_components:
  - source: github://syssi/esphome-modbus-solax-x1@add-solax-x1-mini-g2-compatibility
    refresh: 0s

and recompile + flash your ESP. The payload of your device should be accepted/parsed now.

arxipelagos commented 2 years ago

Thank you for your quick feedback. I tested the new version and the error message doesn't seem to appear anymore. Unfortunately the sun is gone now and the X1 MINI won't start anymore. I'll give you a reply tomorrow..

You have to use three back ticks instead of one for nice code blocks. ;-)

The no errors state and operation mode "Wait" looks good already! Could you provide some details (type label) about your inverter? I would like to mention the supported device at the documentation.

Communication is now stable throughout the day.

I use a SolaX X1 mini inverter model X1-2.0-S-D(L).

syssi commented 2 years ago

Perfect! You should decrease the log level now. ;-) Printing UART traffic is expensive. I will merge the feature branch to main now. Please update your external_component section to:
