Hi everyone,
I’m sharing a new HACS integration that connects to a KEBA heat pump controller via Modbus TCP and exposes operational data as Home Assistant entities.
I have developed it for my M-Tec heat pump. Feel free to test it or open an issue if something is not working

Hello Johannes,
that’s awesome and working perfectly out of the box for my WPS-618.
Just wonder if you looked into monitoring a FriWa (fresh water station) being controlled by the KEBA controller inside the WPS?
It’s in a sub part of the hot water section called fresh water.
I looked for Modbus variables within 20230912_MTec.Modbus_Server_VariableList V2.10.xlsm
but didn’t find a match?
Thank you for your work!
Really appreciated!
Wolfgang
Hi @wriedel,
I am glad that my integration works for you. Yes, you are right. Unfortunately, the Modbus registers do not provide FWM data.
But I can recommend you the Keba Keenergy Home Assistant Integration (GitHub - superbox-dev/keba_keenergy: A Home Assistant integration for heat pumps with a KEBA KeEnergy control system.).
With this integration, it is possible to monitor the FWM Temperature. You can also open an issue on the GitHub repository if you need more values. The developer is really responsive
