Radiator Thermostat – Smart Climate Control

Smart radiator temperature control – for an efficient and comfortable indoor climate. Flexible use within the Bosch Smart Home system or with other manufacturers' devices in any Matter-compatible smart home setup.

Easy to Install

You don't need to be a heating expert to make your radiators smart. Bosch Smart Home thermostats are quick and simple to install without the need for professional help. The app provides clear, step-by-step instructions to guide you through the setup, and with two AA batteries included, your thermostat is ready to use right away.

Designed for flexibility, the smart thermostats fit most radiators—either directly using the standard M30 x 1.5 mm screw thread or with the included adapters (Danfoss RA, Danfoss RAVL). Not sure if you need an adapter? Our adapter check tool makes it easy to find out.

Flexible Heating Control – Your Way

Whether you prefer Alexa, Google Assistant, or Siri with Apple HomeKit®, your Bosch Smart Home radiator thermostats respond easily to voice commands—just say something like, “Alexa, set the temperature in the living room to 22 degrees.”

Beyond voice control, there are multiple convenient ways to manage your heating. You can adjust the temperature directly by turning the knob on the device, use the app from anywhere, set up automations using the IF/THEN principle, create custom time schedules for each room, or define personalized scenarios that link multiple thermostats and smart home devices together.

Reliable Protective Functions

Worried about being left in the cold if your heating fails? In a smart home, you're protected. Smart radiator thermostats come equipped with several safety features designed to minimize the risk of breakdowns. Frost protection helps prevent damage from open windows or unused rooms by keeping radiators from getting too cold. Limescale protection ensures the valve briefly opens once a week, even outside the heating season, to avoid buildup. You’ll also receive a battery warning via the app several weeks before the two AA batteries run low, giving you plenty of time to replace them. For added security, you can set up automations such as “IF room temperature <15°C THEN send message” to stay informed and in control.

Child Lock Function

Curious little hands can lead to unwanted changes and energy waste—but not with the child lock feature.

Easily activate the lock via the app or directly on the device to prevent manual adjustments on the thermostat itself.

This ensures children can’t alter the settings, while you retain full control over the room temperature through the app, voice assistant, or room thermostat.

Set Individual Time Programs

With Bosch Smart Home radiator thermostats, you can tailor your heating schedule to match your daily routine. Create individual time programs for each room—so the bedroom is warm when you wake up, the bathroom is cozy in the morning, and the living room heats up just in time for the evening. Whether your schedule stays the same or changes from day to day, you have full flexibility to adjust heating times to suit your lifestyle—saving energy without sacrificing comfort.
