Hello, I have been trying to start modbus communication between kincony A16 and EastronSDM630 (https://www.eastroneurope.com/products/v...m630modbus) via rs485 using espHome for some time, according to the documentation the registers are identical to kincony.
Log file shows: [17:53:08][D][modbus_controller:040]: Modbus command to device=1 register=0x64 no response received - removed from send queue
I would like to ask if I have something wrong in the .yaml file:
