Smart thermostats begin saving you money the moment you hook it up to your home. Three of the most popular smart thermostats are the Ecobee, Nest and Sensi. These three products allow you to control your homes temperature from your smart phone, pair with virtual assistants like Amazon Echo, and can even learn your patterns and preferences. Each of these thermostats have some key advantages over the others, but the Ecobee smart thermostat has the best features and has a seriously easy set up so anyone can hook it into their home’s HVAC system. Plus, Ecobee’s “Follow Me” feature is one of the coolest things we’ve seen from a smart thermostat, and it sets it over the top as the best smart thermostat you can buy.
