Smart WiFi thermostat Avatto WT20R-EH-16A-W-WiFi

The WT20R-EH is designed for electric underfloor heating systems. It allows you to connect an internal and external sensor, allowing you to accurately control the temperature in the room and on the floor surface. It allows you to conveniently control the temperature in your home - manually and remotely, using the app or voice. With the programming function, precise calibration and compatibility with smart home systems, the WT20R-EH will work well in apartments, homes and offices with underfloor heating. Built-in protection prevents overheating, and adjustable backlight brightness ensures that the device will not be distracting at night.

Remote control via app

The thermostat connects to your WiFi network and works with the Tuya and Smart Life apps, so you can control the temperature from anywhere – from your smartphone or tablet. If you have multiple thermostats at home, you can group them together and control them all at once. Plus, the Family Sharing feature lets you share access to the device with the rest of your household, so everyone can control the temperature from their phone.

Voice control and smart home integration

The device works with popular voice assistants: Amazon Alexa, Google Home, Yandex Alice or SmartThings. To set the temperature or check the current settings, all you need is a simple voice command. This makes the thermostat a great choice for any smart home.

Weekly programming and modes

You can plan a schedule for 7 days a week, with up to 6 time intervals per day. This means that the temperature will automatically adjust to your daily rhythm. You can also choose between manual and program mode.

Precise temperature control

The thermostat allows you to set the temperature with an accuracy of 0.5 °C, and its measurement error is up to ±1 °C. The regulation range is from 5 to 45 °C, and the hysteresis value can be set from 0.5 to 10 °C. This avoids unnecessary switching on of the device in the event of minor temperature fluctuations.

Same summary

The Avatto WT20R-EH-16A-W-WiFi smart WiFi thermostat is suitable for users who want to control the heating in their apartment or house via an app or local interface. Its WiFi connectivity makes it easy to manage comfort, especially if you are looking for a solution that can easily connect to your existing home network. The thermostat is most useful where quick installation and the possibility of remote control are important, but may be less suitable for environments where advanced integration with smart hubs or completely local operation without a cloud connection is expected. When choosing, it is also worthwhile to check compatibility with the selected heating system, especially with underfloor heating or heat pumps.
