Max with dummy sensor from MQTT

[RobinC]

Hi,
I have several Max rad valves working with FHEM. In two rooms the valves are remote, not in the room. I made this work by using a setpoint of 30°C when I wanted them on.
To improve this I have got some Bluetooth sensors which I have connected to FHEM via MQTT. Is it possible to use the readings from these with the valves?

See https://wiki.fhem.de/wiki/MAX#Externer_Temperatursensor_f%C3%BCr_Heizk%C3%B6rperregelung  (sorry, in german).

Basically that should work .

Thankyou,
It's easy to forget about language as my browser translates everything for me.

I've now got something like this (from Wzut via a forum post I found).

My biggest challenge was trying to understand the MQQT2_DEVICE.

I'm now waiting for my CUL queue to clear so I can see if it's all behaving.
