## Summary description

Electronic thermostatic radiator valve controller Homematic IP HMIP-eTRV with RF interface at 868.3 MHz. Features a digital display, AA battery power (1.5 V) and typical power consumption of 120 mA. Compact dimensions (58×71×97 mm) and white housing make it suitable for smart home heating control, per-room temperature regulation and integration into Homematic IP systems.

## Long description

The Homematic IP HMIP-eTRV thermostatic radiator valve controller is an electronic valve actuator for room-by-room heating control within the Homematic IP smart home system. It communicates via RF at 868.3 MHz, is powered by two AA batteries and features a digital display and compact white housing (58×71×97 mm). The device replaces conventional radiator heads and enables automated temperature control, integration with window/door contacts and timed weekly profiles to optimize comfort and energy use.
Advantages
The HMIP-eTRV enables precise per-room temperature regulation and supports up to three separate weekly schedules with up to six heating phases per day, allowing automated temperature changes to match daily routines. Installation does not require intervention in the heating circuit: the unit is fixed to standard valve threads using a metal union nut and supplied adapters for common valves. Low-noise operation makes it suitable for living spaces and bedrooms, while limescale and frost protection functions protect the valve mechanism. In combination with other Homematic IP devices, such as window/door contacts or wall thermostats, it reduces unnecessary heating and contributes to lower energy consumption.
Suitable for
 Smart heating control in apartments and houses
 Individual room temperature regulation (bedrooms, living rooms, bathrooms)
 Integration into Homematic IP smart home systems
 Retrofit of existing radiators with M30 valve connections and Danfoss-compatible valves using supplied adapters

How to use
Mount the HMIP-eTRV onto the radiator valve using the supplied metal union nut or the appropriate adapter for Danfoss-type valves; no changes to the heating system or draining of water are required. Insert two AA batteries and follow the Homematic IP app or gateway instructions to add the device to your Homematic IP installation. Set desired temperatures directly on the device using its controls or configure weekly profiles and scenes in the Homematic IP app. Pairing with window/door contacts or a wall thermostat is done via the Homematic IP system to enable automated setback when windows are open or centralized control of multiple valves in one room.
Usage recommendations
For reliable regulation and long battery life, ensure correct mounting to the valve and select battery types recommended by the manufacturer. Use the Homematic IP app to create weekly profiles and combine the radiator thermostat with window/door contacts to avoid wasted heating during ventilation. Place the device where room temperature measurements are representative for the space and avoid covering the radiator thermostat with curtains or furniture that could affect sensing accuracy.
