Can I use the existing temperature sensor of my old thermostat?

Yes, Themo is compatible with most existing NTC (negative temperature coefficient) temperature sensors.


Themo natively supports the following NTC sensors from these manufacturers:


  • Teplolux / NTC 6.8 kOhm
  • Aube / FENIX / Raychem / NTC 10 kOhm
  • Warmup / OJ Electronics / NTC 12 kOhm
  • Devi / NTC 15 kOhm
  • Eberle / NTC 33 kOhm
  • Ensto / NTC 47 kOhm


If your thermostat manufacturer is not listed here, then Themo might not recognise the correct temperature sensor.


Note: During the setup process, Themo automatically selects the sensor type that is closest to the room temperature at that moment.


You can change your sensor type from the mobile app by navigating to Device > Settings > Configuration > Sensor type.
