Nest Thermostat E

A solid alternative to the Nest Learning Thermostat is the more budget-friendly Nest Thermostat E. The plastic frame (versus metal) is a clear hint you’re in some cheaper territory, but the Nest Thermostat E retains a lot of what we’ve come to expect from a higher end smart thermostat. It doesn’t have the remote sensing or many of the HVAC components you’ll find in the Learning Thermostat, but it also doesn’t have the price tag. Buy it for $169 today.
