Smart Schedules Tailored to Your Life
Set heating schedules in seconds with 5 preset modes, W600 learns your routine, keeps you comfortable at home, and saves energy when you're away.
Once programmed, your schedules will run locally even if the internet goes down, ensuring your comfort remains uninterrupted.
Warm on Arrival
With the Geofencing feature, your heating will automatically turn on as you get closer to home, based on your preset temperature range, ensuring you always walk into a cozy room.
Open Window Detection to Save Energy
If connected to a door and window sensor, the thermostat will pause heating for 30 minutes when a window is detected as open for over 3 minutes and there's a rapid 3°C temperature drop. It then automatically resumes if the window closes. No worries about energy waste.
Thread & Zigbee Dual Protocol Support
With both the Thread & Zigbee protocol, our thermostat connects effortlessly to all major Matter-compatible platforms such as Apple Home, Google Home, Amazon Alexa, Home Assistant, SmartThings, and more.

Precise Temperature Control for Perfect Comfort
External Temp Sensor Linking*
Link your thermostat to an external Aqara temperature sensor to get precise temperature readings from anywhere in the room. Your radiator will then automatically adjust based on these accurate readings, not just around the radiator.
Temperature Calibration**
By adjusting the temperature within a range of ±5°C, you can fine-tune its readings to match your room's actual feel, giving you truly precise control over your comfort.
*Zigbee mode via the Aqara Home app is required to achieve this functionality.
**Only work directly on the built-in sensor.
***Default 2°C temperature swing allows minor fluctuations above or below the set point to improve energy efficiency.
Multiple Ways to Control Your Thermostat
Multi-Device Group Control*
For spaces with multiple radiators, you can group all thermostats together for synchronized control. This means consistent comfort throughout your home.
Ultra Quiet Operation
Our thermostat operates with a noise level below 30 dB, ensuring a peaceful, undisturbed sleep even when running at midnight.
