This wifi thermostat sits flush in the wall and shows the room temperature in large numbers, with the set temperature below it and a red flame icon while the heating is running. Walk in from the cold, tap up on the glass panel or on your phone, and the room moves toward the temperature you chose between 5 and 35 °C.
The M3H wifi thermostat is a flush wall-mounted unit with a square glass touch panel. The LCD display shows the room temperature in large numbers and the set temperature below it in smaller ones, and a red flame icon lights up while the heating is running. You set the target between 5 and 35 °C on the panel or from the phone app over Wi-Fi, and you can lock the panel keys so nobody changes the setting.
It is wired to mains 100-240 V AC 50/60 Hz through screw terminals that take 2 × 1.5 mm² or 1 × 2.5 mm² wire, and the finned rear body sits inside a wall box behind the panel. The 16 A type switches an electric floor heating load and uses an NTC 10K floor sensor cable. The 3 A type switches a gas boiler. Power consumption stays under 1.5 W.
It suits a home with electric floor heating, a water heating system or a gas boiler where you want the heating in one app and a panel on the wall.
It is not a battery unit and it is not built to sit loose on a shelf. The panel is meant to be mounted flush in a wall box and connected to mains wiring. It works with electric floor heating, water heating systems and gas boilers, and it is not made for cooling control.

The product arrived quickly. Setting up and connecting shouldn't be a problem. A major drawback is the measurement of the current temperature. The update time is about 12 seconds, but the delay in displaying the correct temperature can reach 2 minutes or more. The temperature error adjustment does not work correctly.
Very good item and installation is ready. The device with WiFi connects effortlessly with Tuya and the control is really good. One thing to note is when the device is switched off and then on it needs some time to show the right temperature. Order and delivery took around 2 weeks.
Works with floor heating and pairing with the app via Wi-Fi without any problems. I recommend it! Delivery to Warsaw in a week is very fast and efficient.
easy installation (smaller than the 503 box, needs to be adapted) aesthetically very nice, programming via app is a bit difficult
The shipment arrived quickly as scheduled, the packaging was undamaged upon opening, and the item matched the description. I recommend this seller.
It works very well and was easy to install, configure, and sync with Alexa. It is important to connect it to a 2.4GHz WiFi network.

It is wired into a wall box rather than plugged into a socket. The screw terminals take 2 × 1.5 mm² or 1 × 2.5 mm² wire on a 100-240 V AC 50/60 Hz supply, and the rear body sits inside the wall box behind the panel. If you are not comfortable with mains wiring, have an electrician connect it.
