- Easy Installation: Simply unscrew the existing radiator valve and replace it with the meross smart valve in a matter of minutes. No need to connect the boiler. - Voice Control: You can control the thermostat anytime and anywhere by clicking on the Meross app or sending a voice command to Alexa or Google Assistant. Keep the house at a comfortable temperature. - Three Smart Modes: Three independent temperature levels: heating, cooling, and economy. You can program the room temperature according to your needs. When the window is open and the room temperature suddenly drops, the radiator automatically stops heating to avoid energy waste. - More Energy Saved: The Meross smart temperature control valve can be used in separate rooms to save more energy. - Adapter Compatibility: It is compatible with the most common radiator thermostatic valves (M30x1, 5mm connection); includes danfoss adapters (RA, RAV, and RAVL). The Meross thermostatic valves have passed CE and RoHS certifications.
