Min/Max temperature sensor not possible as external temperature sensor

[haagi07]

Hello everybody,

I have a problem with BetterThermostat. I have a long floor with several radiators and several temperature sensors.
I use the Min/Max Helper to find the average temperature in my long floor. Unfortunately I cannot add this sensor as an external sensor in BetterThermostat.
Is there a workaround, or perhaps a timely solution from the developer?

Add a device class of temperature to it
