Aqara announced on 19 November 2025 that its Radiator Thermostat W600 is now available to buy, having first been shown at IFA 20251. The valve is sold through Aqara's own website, authorised retailers and Amazon in France, Germany, Italy, the Netherlands, Poland, Spain and the UK1.
The W600 is a smart TRV that replaces the existing head on a radiator. Aqara says it supports up to seven temperature periods per day per room, and can adjust heating using occupancy and geofencing triggers, so a room can be warmed before someone returns home or left unheated when empty1. Paired with contact sensors, it can pause a radiator when a window is open1. Temperature is set in increments of 0.5°C, and multiple radiators can be grouped for synchronised control1. Aqara states the unit runs below 30 dB and gives up to two years from two AA batteries, which it says is double the life of the previous model1. That battery figure is calculated on roughly eight months of active operation a year in Thread mode, and Aqara notes actual life varies with use1.
Connectivity is the main change. The W600 carries both Thread and Zigbee1. In its default Thread mode Aqara says it is natively compatible with Matter, so it can be used with Alexa, Apple Home, Google Home, Home Assistant, Homey and SmartThings without a proprietary hub1. Switching to Zigbee mode requires an Aqara Zigbee hub and unlocks features in the Aqara Home app, including smart schedules, multi-device grouping, remote control with a paired Aqara device and heating regulation based on a paired Aqara temperature sensor1. Aqara says the valve fits M30 x 1.5mm threads and ships with adapters for RA, RAV, RAVL, Caleffi, Giacomini and M28 x 1.5mm valves1. It has a flippable LED display and can be mounted horizontally or vertically1.
"With the Radiator Thermostat W600, Floor Heating Thermostat W500, and Climate Sensor W100, each supporting Thread/Zigbee dual protocol, Aqara has introduced a next-gen HVAC control lineup for the European market, seamlessly integrating with various heating systems and smart home platforms."
Aqara also says the W600 can be paired with an external temperature sensor such as the Climate Sensor W100 or Presence Multi-Sensor FP300, because the built-in sensor can be affected by its proximity to the radiator1. Remote control through a paired Panel Hub S1 Plus may not be available at launch, the company notes1. No UK price is given in the announcement1.
Why it matters for households
A smart TRV shifts control from one thermostat for the whole house to per-room scheduling, which is the mechanism by which a household stops paying to heat rooms it is not using. For a home's energy independence, the practical effect is narrower than a boiler change: it reduces demand rather than changing where energy comes from, and it works with the radiators already installed. Whether that translates into lower bills depends on the heating system, the tariff and how the house is occupied, and Aqara's announcement does not include measured savings figures1. Households weighing whether smart heating controls actually save money will find the claim here is about avoided heating in unoccupied areas rather than a stated percentage1.
Two details matter for buyers. First, the choice between Thread and Zigbee is not cosmetic: Matter over Thread works without an Aqara hub, while the advanced Aqara Home features need one1. Second, valve compatibility decides whether the unit fits at all, and Aqara lists the adapters supplied1. The Aqara heating controls range sits alongside other heating control manufacturers offering Matter-compatible valves.
What happens next
Aqara has not reported a date for Panel Hub S1 Plus remote control support, saying only that it may not be available at launch1. No UK pricing or wider availability dates beyond the seven named markets have been reported1.
