Hi, After installing my second Deye inverter of the same type with ESPHome according to the instructions with the same ESP32 WROOM and the same converter, I get the following error logs about 4 days after problem-free data transfer.

My configuration is the following:

The other system runs absolutely problem-free, where could the error be? Thank You

If it has been working at you now get errors, I would try a new ESP32 + UART-Modbus converter board. I have tried multiple and failed. The quality is not very consistent. Also try to use "Skip_update" on paramenters you do not need updated as often, maybe the Time of use data. Also 10s updates is quite often, if I go lower I get errors as well. Maybe try to set it to 15s, as a test.
