The device uses Matter over Thread technology, which allows it to work with popular smart home systems such as Apple Home, Google Home and Amazon Alexa. It allows you to remotely control your heating via an app and voice commands, as well as create schedules tailored to your daily routine. The open window detection function helps reduce energy loss, heating history makes it easy to monitor costs, and automatic maintenance ensures the valve is working properly. Thanks to the M30 × 1.5 connection and 6 adapters included in the kit, the thermostat fits many popular radiator valves. \u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"A white smart thermostatic head mounted vertically on a copper pipe next to a white radiator.\" src=\"https:\/\/assets.innpro.pl\/25465\/33697\/2-1f47a9ec-3d12-4208-bf55-bb35dab1dec2.jpg\"\u003e\u003c\/p\u003e\u003ch3\u003e Smart management of matter instead of thread\u003c\/h3\u003e\u003cp\u003e The MEROSS MTS155MAT can be integrated with various smart home systems and adjust the temperature using the app or voice commands for Siri, Alexa and Google Assistant.
