Aqara Smart Thermostat W600

The Radiator Thermostat W600 is a smart radiator valve designed to bring more control to room-by-room heating, without turning the setup into a science project. It supports both Thread and Zigbee, which gives it a split personality in a good way: Thread lets it join major Matter platforms like Apple Home, Google Home, Alexa, Home Assistant, and SmartThings, while Zigbee through the Aqara Home app unlocks deeper features like local schedules, external sensor linking, frost protection, grouped control, and automation with other Aqara devices. It also covers the practical stuff people actually notice day to day, such as 0.5°C manual adjustment, an LED display that can rotate 180°, operation under 30 dB, and battery power from two AA cells.

What makes the W600 more than a basic thermostat is how it handles comfort in a lived-in home. It can run scheduled heating locally even if the internet drops, turn the heat on as you get close to home with geofencing, and pause heating when a window is open and the room temperature suddenly falls. Paired with an external Aqara temperature sensor, it can react to the temperature where people actually sit or sleep, not just the warmer air around the radiator. The unit fits standard M30 × 1.5 radiator valves and ships with six adapters for broader valve support, which matters because radiator hardware is rarely one-size-fits-all. In plain terms, this is a dual-protocol smart radiator thermostat built for quieter operation, tighter temperature control, and more thoughtful energy use.
