Meross electric heating thermostat 16 A

For electric underfloor heating you want to manage around your daily routine, this Meross thermostat combines touchscreen controls with app-based scheduling and voice control. It supports Matter and is listed as compatible with Apple HomeKit, Home Assistant, Alexa and Google. The practical appeal is being able to set a timetable or adjust the temperature without relying on voice commands, the main catch is that it needs specific Wi-Fi and wiring conditions, so it won’t suit every installation.

Quick overview

This is a 16 A thermostat intended for electric underfloor heating. Its temperature range is 5°C to 35°C, with stated accuracy of ±0.5°C, and the touch display lets you change settings at the wall. Five operating modes are listed: manual, auto, heating, cooling and absence. The product is designed for underfloor heating, though, so the inclusion of a cooling mode shouldn’t be taken as evidence that it can operate a separate cooling system.

In the Meross app, you can set up to eight time periods and use a weekly schedule to match heating to your routine. For example, you could schedule the floor to warm up before you get home, rather than leaving it running at the same setting all day. Window-open detection is also listed: after a sudden temperature drop, the thermostat stops heating for 30 minutes and sends a notification. That behaviour may be useful, but the description doesn’t explain how the drop is detected or how the feature is configured.

How to use it

Use the touchscreen for direct temperature adjustments, or set a schedule in the app and use a compatible voice assistant for hands-free changes. The controls are said to work without a network connection, while app access and remote operation depend on a 2.4 GHz Wi-Fi network. Matter support may help it fit into a compatible smart-home setup, but it doesn’t remove the thermostat’s physical installation requirements.

Keep in mind that it requires a flush-mounted box suitable for 86 mm or 67 mm fittings, plus both live and neutral conductors. It is specified for electric underfloor heating only. If your existing thermostat uses different wiring, or you’re unsure what’s behind the wall, check the installation requirements before choosing it rather than assuming it’s a straightforward swap.

Practical tips

Plan the schedule around when the floor needs to feel warm, not just when a room is occupied. A bathroom, for instance, may benefit from a morning heating period, while a room used occasionally could be better suited to manual or absence mode. The child lock and LCD backlight are useful details for a wall-mounted control, and optional external sensors are supported for more specific temperature measurement, including in bathrooms, saunas and on sensitive floors. The description doesn’t say whether a sensor is included.

It may suit you if you want app scheduling, voice control and Matter compatibility for an electric underfloor heating setup. It may not be the best fit if you need a thermostat for a different heating type or don’t have the required Wi-Fi and wiring. Compared with a basic wall controller, this adds connected controls and scheduling, a simpler unit may make more sense if you only need to adjust the temperature at the wall.

Three specific questions

Does it need Wi-Fi for every adjustment? The touchscreen is stated to work without a network connection. App access and remote control require 2.4 GHz Wi-Fi.

Can it control gas or hydronic heating? It is described as being for electric underfloor heating only, so the listing doesn’t establish support for those systems.

Can it pause heating if a window is opened? Window-open detection is listed. Following a sudden temperature drop, it pauses heating for 30 minutes and sends a notification.

In your case

Choose this Meross model if your system is electric underfloor heating, the flush-mounted box and live-and-neutral wiring match, and you’ll use its schedules or smart-home controls. If any of those conditions don’t apply, a basic controller suited to your existing installation—or a thermostat made for your heating type—is the more sensible direction.
