Nest is one of the best Wifi thermostat products on the market. It continuously learns about your heating and cooling preferences, so you don’t have to worry about adjusting the thermostat multiple times throughout the day. After one to two weeks of use, the thermostat will remember your habits and begin to set the temperature automatically. You also have the ability to make changes from the Nest app, so if you want to make any adjustments when you’re away from home, you can. Read the rest of our Nest learning thermostat review to see if it’s a good fit for your household.
