Bosch Radiator Thermostat V2 only detected as sensors — no climate entity available #155303
Description
The problem
Hi everyone,
I'm new to Home Assistant and just getting started with integrating my Bosch Smart Home setup — so apologies in advance if I missed something obvious.
I'm running the latest version of Home Assistant (2025.10.x) in Docker on a Linux system. The Bosch Smart Home Controller (SHC) integration is working in general — I can see multiple devices and their states.
However, my Bosch Radiator Thermostat V2 (model BTH-RM2) is not recognized as a controllable climate entity.
Instead, I only get the following sensors:
- sensor.radiator_battery
- sensor.radiator_valve_position
- sensor.radiator_temperature
There is no climate. entity, so I cannot set the target temperature or change HVAC modes via Home Assistant.
System details:
- Home Assistant Core: 2025.10.x (Docker)
- Bosch SHC hardware version: 1
- SHC firmware: 10.30.5053-4139
- Thermostat model: Bosch Radiator Thermostat V2 (BTH-RM2)
What I've tried:
- Reloaded the Bosch SHC integration
- Restarted both SHC and Home Assistant
- Removed and re-added the thermostat in the Bosch app
- Checked logs (no relevant errors regarding climate entity creation)
Question:
Is support for Thermostat V2 fully implemented in the current integration? Are there known limitations with SHC firmware 10.30.x? Is there anything I can do to manually expose the climate. entity?
Thanks in advance for your work and support — and again, I'm new here, so I really appreciate any guidance!
