The Aqara W500 is a smart floor heating thermostat designed to manage your home's warmth through a variety of connectivity options, including Bluetooth, Thread, and Zigbee. It integrates seamlessly with major ecosystems like Apple Home, Google Home, Amazon Alexa, and SmartThings, allowing you to adjust temperatures via physical buttons, a mobile app, or voice commands. This device supports both electric floor heating with live and neutral wires and hydronic systems using 2-wire 230V normally closed actuators, making it versatile for different installation types. With a maximum power capacity of 3600W and a 16A current rating, the thermostat handles resistive loads efficiently while providing detailed power metering to help you track energy use. You can create smart schedules with up to seven intervals per day and customize the temperature swing range between 0.5 and 3°C to maintain a consistent climate. The unit includes a built-in temperature and humidity sensor and supports an external NTC floor sensor for more precise readings. Measuring 86 x 86 x 45 mm, the device fits into standard 86mm or EU round wall boxes and weighs 244 g. For safety and reliability, it features anti-freeze protection and safeguards against overload, as well as overheating for both the floor and the device itself. A power-off memory function ensures your settings are preserved after an electrical interruption, which is helpful for maintaining your preferred comfort levels without manual reconfiguration.
