SwitchBot Smart Radiator Thermostat, Thermostat App and timer control, energy-saving, easy installation, compatible with Alexa, Apple Home Assistant (hub required)

【SMARTER HEATING, LOWER COSTS 】 – Why keep paying to heat an empty home or lose warmth through an open window? This smart radiator thermostat heats only when need. Open Window Detection temporarily closes the valve when a sudden temperature drop is detected, helping reduce heat loss during ventilation. It can help reduce heating costs by around 30%, while upgraded temperature regulation delivers steadier, more comfortable control. 【SET IT ONCE, STAY COMFORTABLE】– This thermostatic radiator valve lets you create Smart Schedules around your routine. Warm the room before you wake up or arrive home, lower the heat when everyone leaves for work or school, and switch to a sleep-friendly temperature at night. Once set, it adjusts automatically—no daily app checks or repeated manual changes, just a comfortable room at the right time. 【SMART UPGRADE, NOT A RADIATOR REPLACEMENT】– No new radiators, no plumber, no heating-system changes. Simply screw on the smart thermostatic radiator valve. A new built-in anti-loosening design helps keep it secure during manual adjustments and everyday use, reducing accidental loosening. Six adapters—Danfoss RA, Danfoss RAV, Danfoss RAVL, M28x1.5, Giacomini and Caleffi—are included to fit most common radiator valves. 【FLEXIBLE CONTROL WITH NO SUBSCRIPTION】– Heating control should make life easier, not add another monthly bill. Adjust this smart thermostat directly using its dial or through the SwitchBot App within Bluetooth range. Smart Schedule, temperature adjustment and Bluetooth App control require no Hub or mandatory subscription. Remote and voice control require a compatible SwitchBot Hub, while Matter integration requires a Matter-enabled SwitchBot Hub. 【QUIET, RELIABLE COMFORT THROUGHOUT THE HEATING SEASON】– Designed for bedrooms, children’s rooms and everyday living spaces, this smart radiator thermostat operates at noise levels as low as 20 dB. Battery life reaches up to 10 months under test conditions of 10 temperature adjustments per day. Low-battery alerts, a clear digital display, child lock, frost protection and automatic limescale protection provide additional reassurance.
