Key Takeaways

Best for: Electric baseboard and wall heaters
Standout: No subscription and a 5-year warranty
Watch out: Needs 4 wires, including a neutral
Not for: 24V furnaces or central heat pumps

The Mysa Smart Thermostat LITE is a smart thermostat for 120V and 240V electric baseboard and wall heaters, which most smart thermostats cannot control. It needs no subscription and sells for about $90 to $110.

What you need before you buy

Line-voltage electric heat (baseboard, wall, convector or radiant ceiling).
Four wires at the thermostat, including a neutral or second live wire.
An electrician if local code requires it or you are not comfortable with high voltage.

How it saves energy

Schedules and geofencing turn heaters down while you are out and warm rooms before you return, which Mysa says can save up to 26% on heating.

Common Questions

Will it work with my furnace?: No. It is only for 120V or 240V line-voltage heaters such as baseboards. For a furnace or central heat pump, choose a 24V thermostat like the Google Nest Thermostat.
Do I need a neutral wire?: You need four wires, including a neutral or a second live wire. It will not work on a two-wire switch loop.
Is there a subscription?: No. Scheduling, voice control, geofencing and the monthly runtime email are all free.
