Aqara smart radiator head discounted below a thousand! Connects to Matter even without an Aqara hub

Heat up the bedroom before the alarm and preheat the living room before returning from work. This is what the smart thermostatic head Aqara W600 promises, which you can get on Alza for 952 Kč with code ALZADNY25. Without the code, it costs 1 269 Kč.

More interesting than the scheduling itself is that the head doesn’t tie you to a single ecosystem. It supports both Thread and Zigbee, so you can connect it directly to Matter, or connect it to an Aqara hub to use additional features.

Quick summary:
✅ Makes sense if: you want to control radiators from Apple Home, Google Home, or Home Assistant via Matter and don’t want to buy an Aqara hub for it.
⚠️ Consider: the rating of 2.9 out of 5 from 17 customers and the type of valve on your radiator. Alza lists RA, RAV, and M30 valves, and there are six adapters in the package.
💡 Code ALZADNY25 saves 317 Kč compared to the current public price. However, the head is currently in transit, not in stock.

Thread for Matter, Zigbee for Aqara features

The W600 has two modes, and you can switch between them. In Thread mode, the head connects to other manufacturers’ systems via Matter and, according to the description, does not require an Aqara hub for this. Zigbee mode is useful if you already have a classic Aqara hub at home. Then you also get features that Aqara doesn’t offer elsewhere.

The head does not connect to the network independently. The specifications state operation via a central unit or bridge. The description does not specify what particular device must be running in your home in Thread mode.

You can control it by turning it directly on the radiator, from the Aqara Home app, which is also in Czech, or by voice. The temperature is set from 5 to 30 °C in half-degree increments.

It can measure temperature by the bed, not by the radiator

The radiator head measures temperature directly at the heat source. Aqara therefore offers connection with the W100 climate sensor. The head then regulates according to the temperature measured by a sensor placed elsewhere in the room, and the manufacturer promises more accurate measurement.

If you have multiple radiators in a room, you can group the heads to maintain the same temperature together. Geofencing 2.0, in turn, starts heating according to a preset temperature range when you approach home. Additionally, there’s open window detection, child lock, and frost protection.

Check the valve before ordering

Alza states compatibility with RA, RAV, and M30 valves. In the box, you will find six adapters, including for RAVL, Caleffi, Giacomini, and M28 × 1.5 thread. The head itself measures ⌀57 × 90 mm, which is worth measuring for radiators close to a wall or furniture.

It is powered by two AA batteries, which are included in the package. According to the manufacturer, they last up to two years. The stated noise level is below 30 dB, and the LED display can be rotated 180°, so you can read it even if the head is on the valve from the other side.

A rating of 2.9 out of 5 is a warning sign

The features and connectivity are strong on paper. However, Alza customers have so far rated the head only 2.9 out of 5 stars from 17 reviews.

The most frequent complaints about the Aqara W600 concern the temperature regulation itself. Some owners describe rooms being overheated, while others report situations where the head does not start heating even though the temperature is significantly below the set value. There are also complaints about not adhering to the schedule. A recurring problem is cooperation with an external temperature sensor – according to some reviewers, it connects in the application, but the head continues to rely on its own measurement for regulation. One customer also points out difficult calibration and selecting the correct pin when mounting with a 28mm adapter; for them, the difference between the desired and actual room temperature reached up to 4–6 °C.

However, experiences are not uniform. One buyer stated in March that the update to firmware 0.0.0_2745 resolved the issues. However, another significantly negative experience with regulation also appeared in October, albeit without mentioning the firmware version. Therefore, it cannot be concluded from the reviews that the update eliminated problems for everyone. On the other hand, multiple customers agree on its very quiet operation.

Do you control your radiators with smart heads, or do you still turn the dial manually?
