  3. A set of functions. It is the most important component of any highly intelligent device. Here, pay special attention to the possibility of connecting additional sensors to the thermostat, establishing remote communication with it, the number and complexity of the operating scenarios that it supports.

  5. Manufacturer. When buying a smart thermostat, give preference to the companies that have proven themselves in the smart equipment market.
