Hy
I have been using an esp32 board + TTL / rs485 adapter to receive input from an ORNO WE-525 energy meter. All this worked flawlessly for many months, until my sensors showed up as “unknown” with this type of logs :
[modbus_controller:040]: Modbus command to device=1 register=0x100 no response received - removed from send queue
My ESP32 board appears as Online in ESPHome, I can edit and load new yaml scripts, the wifi signal is fine, so I do not think the problem lies in the board.
Perhaps a problem occured with the ORNO energy meter itself, but this sudden loss of contact seems quite surprising.
Below are my esphome logs
Has anybody run into the same kind of problem ?
Thank you for any help !
