How much can smart home devices save on energy?

A comprehensive setup—thermostat, smart plugs, LED lighting—can reduce energy bills by 20 to 30 percent. The thermostat alone typically saves 10 to 20 percent on heating and cooling.

Do smart plugs use energy themselves?

Smart plugs use about 1 watt each, costing roughly one dollar per year. They save far more than they consume by eliminating standby power.
