Thermostatic Radiator Valve Homematic IP HmIP-eTRV-ES, RF 869.65 MHz, Digital Display, Battery AA, Grey

Homematic IP HmIP-eTRV-ES is a battery-powered thermostatic radiator valve that provides room temperature control for standard radiators. The device operates on the RF band at 869.65 MHz and includes a built-in digital display for setpoint and status information. Its compact grey housing (approx. 53 × 55 × 94 mm) and AA battery power make it suitable for retrofit installation without mains wiring when integrated into compatible Homematic IP systems.

Advantages

The valve offers precise temperature regulation via the integrated sensor and electronic actuator, enabling stable room climate control. Wireless RF communication ensures reliable connection with Homematic IP hubs and sensors for remote control and automation. The digital display simplifies local operation and feedback, while AA battery operation permits installation where power outlets are unavailable. The compact form factor minimises interference with radiator fittings and interior design.

Suitable for

• Controlling temperature of domestic radiators in living rooms, bedrooms and offices
• Retrofit installation on existing radiators without additional wiring
• Integration into Homematic IP smart heating schedules and automations
• Rooms requiring individual temperature setpoints or zoning

How to use

Install the thermostatic radiator valve on the radiator according to the radiator manufacturer’s instructions and the adapter guidance supplied by Homematic IP. Insert the AA battery and use the device display and controls to set the desired temperature. Add the valve to a Homematic IP system using the central access point or app to enable remote control, scheduling and integration with other devices. After pairing, adjust setpoints or schedules from the app or via linked thermostats and sensors.

Recommendations

For reliable operation, install the valve on radiators with appropriate mechanical adapters and ensure line-of-sight or minimal RF obstructions to the Homematic IP access point. Replace batteries when indicated on the display and follow local recycling rules. Use in combination with room sensors or central controllers for optimal energy efficiency and comfortable temperature management.
