Bosch Smart Home - BHT-RM Zigbee II room thermostat

Bosch Smart Home Room Thermostat II: Precision Climate Control All Year Round

The Bosch Room Thermostat II offers accurate temperature regulation for any room, whether in summer or winter. It functions as both a remote sensor for radiator thermostats and an intelligent controller for fans or roller shutters, responding to rising temperatures. Designed for flexibility, it can be wall-mounted or used as a portable unit, and integrates seamlessly with the Bosch Smart Home system.

Targeted Temperature Measurement, Where You Need It

Placed anywhere in the home, the Room Thermostat II captures the exact temperature and communicates it to your radiator thermostats. This leads to more accurate and efficient heating, especially when compared to relying solely on thermostats attached to radiators.

Real-Time Temperature and Humidity Display

Featuring a modern LED matrix display and LED light strips, the thermostat shows current room temperature and operating status at a glance. The LED display also provides humidity alerts: blue flashes for humidity above 70%, yellow for below 30%, and stays off under normal conditions.

Portable or Fixed – You Choose

Use it as a portable unit or mount it on a wall with the included bracket and adhesive. Its compact design (86 × 87 × 28 mm) fits discreetly into any room, and it can be placed wherever temperature monitoring matters most—like near seating areas in winter or near windows in summer.

Smart Humidity Monitoring

Beyond temperature, the Room Thermostat II also monitors humidity. It alerts you visually when humidity levels exceed healthy thresholds, helping you maintain optimal air quality and reduce the risk of mold. Ideal for sensitive individuals or maintaining a healthy indoor environment.

Automation for Every Season

Connect the thermostat to the Bosch Smart Home Controller to automate fans and roller shutters during hot days. Use smart rules like:

• IF temperature exceeds 27°C, THEN close roller shutters automatically.
• IF temperature exceeds 27°C, THEN turn on the fan using a smart plug.

Indoor Climate Optimization with Smart Automations

Pair the Room Thermostat II with other Bosch smart devices for complete indoor climate control. Create automations using temperature and humidity data:

• IF humidity drops below 35%, THEN activate a humidifier via a smart plug.
• IF humidity exceeds preset values, THEN receive a ventilation reminder.

Child Lock for Safety

Prevent unintended adjustments with the child lock feature. Activate it either via the app or directly on the device by pressing and holding the system button for 3 seconds and turning to lock. Control remains with you—through the app interface.
