Hello everyone,
It’s all good, I’m finished, I spent hours and hours on it, but I managed to read the information from my EM112 (Energy Monitor) commonly used by Wallboxes so as not to trip the facilities.
The Modbus integration (which is the protocol) is integrated into HA, on this side, it’s quite simple, for everything else, I have detailed everything as usual:
If someone masters RS485 and finds a way to sniff it instead of integrating with it, to avoid having two “master” devices on the bus, I am interested because at this stage, I cannot let the connection on the bus, I am afraid of disturbing my wallbox when it interrogates the EM112.
