Tuya Smart Thermostat Radiator Valve Actuator — Mobile App & Voice Control Energy-Saving Temperature Controller

Compact, user-friendly soft-press design with clear LED display: A slim, modern radiator valve actuator with a high-visibility LED readout and a wide viewing angle for easy temperature checks. The unit is powered by two AA batteries and mechanically controls the radiator valve to open and close the pipe for comfortable room temperature. Pairing is fast and simple for immediate use. Flexible local control and stable mesh connectivity: You can control a single valve directly from the mobile app without a gateway or home network—only a smartphone is required. For whole-home setups and remote access, this device supports Sigmesh networking; Sigmesh remains reliable even if the local network drops, and a gateway enables broader multi-device automation. Accurate sensing and external sensor support: An external sensor on the valve delivers precise temperature readings for smarter regulation. Features include ECO temperature settings and low-battery notifications to help minimize power use. Advanced scheduling and modes: Create custom weekly programs using 5+2 or full 7-day schedules with up to 5 periods per day. The controller also offers Holiday mode, Automatic mode, and Manual mode, plus window-open detection and an adjustable offset temperature for fine-tuned comfort. Voice and remote operation (gateway required): When connected through a gateway, the valve supports remote app control and hands-free voice commands via compatible smart speakers, enabling convenient voice-operated heating control.
