Please increase the log level to DEBUG and provide another log: https://github.com/syssi/esphome-smg-ii?tab=readme-ov-file#debugging

Could you take some photos of your wiring and RS485 module? I guess your wiring isn't correct or the flow control is not properly managed.

cyclemat commented 3 months ago

RS485 ? in the readme stands RS232 !

Here are Pictures will set the debug level this evening !

RS485 ? in the readme stands RS232 !

My fault. It's RS232! :-)

syssi commented 3 months ago

Could you check the chip model of your RS232 converter? It's important to use the MAX3232 (3.3V model) and no MAX232 (5V model).

cyclemat commented 3 months ago

Will check but i have buy IT as 3,3v habe ordered new ones to test
