I bumped into this GitHub - CreasolTech/domoticz-emmeti-mirai: EMMETI Mirai heat pump plugin for Domoticz home automation system. Hopefully ti might be of some help (@PdC ) to integrate emmeti febos into HA.
Thx. Since I already have A Febos Crono I cannot add another client to the modbus (there can be only one on a RS485 modbus. If it were MODBUS/TCP it would be a different story.). But for those without a crono this would suffice. I just wish that Mirai/Emmetti would open up the Febos Crono so I could talk to the local API and no longer be dependent on the cloud service they provide…
