Cost Savings Through Spatial Intelligence: Connects with Aqara presence and temperature-humidity sensors in automations to reduce energy costs by managing each room independently. Heating automatically switches off in unoccupied spaces and maintains the perfect temperature in rooms that are in use. With intelligent scheduling①, you can tailor heating to your family’s lifestyle—such as warming the bedroom before you wake up in winter or preheating the living room before arriving home from work. This ensures every room is comfortable when needed and energy-efficient when not. And with upgraded Geofencing 2.0②, heating can now start automatically as you head home, based on your preset temperature range, while supporting multiple users with no hidden fees.
-
Thread/Zigbee Support: The device features dual protocol support. In Thread mode, no Aqara hub is required to connect to third-party Matter ecosystems③, while Zigbee mode④unlocks exclusive Aqara features and ensures backward compatibility with the classic Aqara Zigbee hubs without compromising Matter support. The flexible protocol switching lets users enjoy Matter integration or Aqara's advanced functionalities based on their preference.
-
Precise Temperature Control: With 0.5 °C adjustment increments and temperature calibration⑤, the Radiator Thermostat W600 allows for precise control tailored to your comfort. It not only improves home comfort but also provides an optimal health environment for sensitive people. Furthermore, the Radiator Thermostat W600 can be connected to additional sensors, such as the Aqara Climate Sensor W100, allowing the device to directly read the temperature based on the linked external sensor, making temperature detection more accurate.
-
Extended Battery Life: With up to 2 years of battery life⑥, the W600 provides reliable temperature control without the worry of frequent maintenance. This long battery life means you can enjoy consistent comfort while minimizing the environmental impact of frequent battery changes.
-
Control with Ease: The Radiator Thermostat W600 offers flexible control features to suit any lifestyle. In addition to voice, app, and manual control, the device can also connect to the Aqara Climate Sensor W100 for instant control via the W100's physical buttons⑦. For rooms with multiple radiators, the Multi-Device Grouping feature lets multiple units work together to maintain a consistent temperature, ensuring simple and efficient heating management.
-
Worry Free Living: The device is designed to make your life easier and more comfortable. Its LED display rotates 180° for easy reading from any angle, so you always know the exact temperature. Ultra-quiet operation (below 30 dB) ensures restful sleep even at night. Built-in Frost Protection⑧ prevents freezing in cold weather, keeping your home safe and your heating system protected—giving you peace of mind all year round.
