Key features of the W600 radiator thermostat
Smart schedules & geofencing
The W600 allows you to create heating schedules with five preset modes – this makes it possible, for example, to automatically regulate the temperature depending on the time of day. The device also supports geofencing. If the resident is on their way home, the heating can start automatically so that a comfortable temperature awaits them upon arrival. The schedules run locally further, even if the internet connection fails.
Window detection for energy saving
If a window is open for more than 3 minutes and a rapid temperature drop of ≥ 3 °C is detected, the thermostat pauses the heating function for 30 minutes – the heating restarts as soon as the window is closed. This is a useful feature for reducing energy waste caused by open windows.
Advanced temperature control & sensors
- It is possible to use an external temperature sensor from Aqara, such as the Room thermostat W100, so that not only the immediate surroundings of the radiator are taken into account, but also the room temperature at a representative location.
- A calibration within a range of ±5 °C can be performed to adjust the measured temperature to the actual room temperature.
- Temperature changes can be adjusted in fine increments of 0.5 °C.

Networking & Compatibility
The W600 supports both the Zigbee and Thread wireless protocols, making it compatible with modern smart home systems such as Apple Home, Google Home, Amazon Alexa, Home Assistant, and SmartThings. This simplifies integration into existing smart home infrastructure.
Installation & technical data
- Dimensions: Ø 57 mm × 90 mm.
- Connection: M30 × 1.5 and adapter set (6 pieces) for common radiator valves (RA, RAV, RAVL, Giacomini, M28×1.5, Caleffi) are included in the scope of delivery.
- Power supply: 2 × AA batteries (typical operating time estimated at up to 2 years)
- Operating temperature: 0 °C–40 °C.
- Noise level: Below 30 dB during operation, so it is hardly noticeable even in the bedroom.
Noise level: Quiet 30 dB during operation
A major advantage of the W600 is its very low operating noise level. Aqara gives a value of below 30 dB to.
What does that mean in practice?
30 dB corresponds approximately to:
- the noise level of a quiet apartment
- a gentle whisper
- the background noise on a quiet night
This means the actuator of the W600 significantly quieter than many conventional radiator thermostats. Even in bedrooms or offices, the adjustment is barely noticeable. Only during rapid adjustments might a faint whirring be heard, but at a level that is hardly perceptible to most users.
The actual volume depends, however, on also The noise level depends on the environment, installation, valve mechanism, and room acoustics – if the valve is mechanically noisy or poorly installed, even a "quiet thermostat" can become audible. In fact, forums point out that audible noises have occurred with thermostats from other brands ("stepper motor").
Who is the W600 suitable for?
- For homeowners or tenants with radiators who want to make their heating control smarter and reduce heating costs.
- For smart home enthusiasts who already operate a system with Apple Home, Google Home, Alexa or Home Assistant and want to seamlessly integrate thermostats.
- For users looking for a simple solution to automatically control heating times or to save energy in absence or "window open" situations.
Conclusion
The Aqara W600 radiator thermostat impresses with its wide range of features: It combines smart control, convenient functions such as window detection and geofencing, and modern wireless protocols in a compact device. For those who already operate or plan to install a smart home system and have radiators with compatible valves, this is an excellent solution for increasing both comfort and energy efficiency.

FAQs – Answers to frequently asked questions
How quiet is the Aqara W600?
The engine operates with below 30 dB. This is roughly equivalent to a quiet whisper or a quiet apartment – ideal for bedrooms or studies.
Does the W600 detect open windows?
Yes. The thermostat detects a rapid temperature drop (approx. 3 °C) and then automatically switches off the heating for about 30 minutes to save energy.
Can I use external sensors?
Yes, the W600 can be paired with external Aqara temperature sensors to regulate the room temperature even more precisely.
What type of batteries does the W600 require and how long do they last?
The thermostat uses 2 × AA batteries.
The battery life – depending on usage – is typically… 1 to 2 years.
Can the W600 also work without internet?
Yes. Schedules and basic automations are running. locally further, even if the internet connection is interrupted.
Can I operate the W600 manually?
Yes. The device has a rotary and push-button dial as well as a display, which allows the temperature and modes to be controlled directly on the thermostat.
Is the W600 suitable for renters?
Yes. Since the installation can be reversed without leaving any residue and only the valve is replaced, the W600 is generally also suitable for rented apartments.
