If you decide to make climate control in the house more convenient, you need to know about the automatic system. these systems are divided into Programmable and Smart WiFi.

Programmable – allows you to control heating and cooling. For the system to work, you just need to make a schedule. Restrictions vary by model.
Smart WiFi is smart thermostat with WiFi function. This is a more modern system. It allows you to use a smartphone, tablet or computer to control your settings. These devices include Ecobee thermostats.

If you have not used smart thermostats before, then at first it will be unusual for you to work with it. But the use of such a thermostat will open for you many useful functions.

First of all, these are zone sensors. This is a good purchase for a multi-level house with an open architecture. Ecobee room sensors allow the thermostat to read the temperature and occupancy locally.

The second useful feature is the control of the heating, ventilation and air conditioning system from a smartphone. Thanks to its wireless connection, you can control the system from wherever you are.

Also with the Ecobee Switch+ you can do the voice control of the thermostat. To do this, you must have a device that supports integration with Alexa.
