## Long description

The Homematic IP Radiator Thermostat (Thermostat Homematic IP HMIP-eTRV) is a battery-powered digital radiator valve actuator for the Homematic IP smart home system. It replaces conventional radiator thermostats, fits M30 valve threads and comes with adapters for Danfoss valves. The device is powered by two AA batteries and can operate for up to 2 years. Control is possible directly at the thermostat, via the Homematic IP Wall Thermostat, or through the Homematic IP app using RF communication at 868.3 MHz.
Advantages
The thermostat enables automated temperature control and can reduce heating energy consumption by up to 30% through programmable weekly profiles and integration with window/door contacts. Installation requires no intervention in the heating circuit thanks to the supplied metal union nut and adapters. A low-noise gearbox allows use in bedrooms and children's rooms, while integrated limescale and frost protection protects the valve and prolongs device life. Compact dimensions and AA battery power make the device easy to install and maintain.
Suitable for
Replacing manual radiator thermostatic heads on M30 valves (e.g., Heimeier)
Retrofitting apartments or houses with Homematic IP heating control
Rooms where weekly scheduling and remote control are required (living rooms, bathrooms, bedrooms)
Integration with Homematic IP window/door contacts to avoid wasted heating

How to use
Install the valve head onto the radiator valve with the included metal union nut or Danfoss adapter without altering the heating system. Insert two AA batteries and follow the Homematic IP app or Wall Thermostat instructions to add the device to the Homematic IP system. Set desired room temperature directly on the device, via the Wall Thermostat, or in the app. In the app, create up to three weekly profiles with up to six heating phases per day to automate temperature changes. Optionally pair with Homematic IP Window/Door Contact devices so the thermostat reduces heat output automatically when a window is detected as open.
Usage recommendations
For optimal energy saving and comfort, create separate weekly profiles for different rooms, use window/door contacts in frequently ventilated rooms, and replace batteries promptly when the app indicates low battery. Avoid forcing the valve manually to prevent damage to the actuator.
