Buying Guide: Smart Thermostats

Control Your Home Comfort
The Sensi thermostat lets you control heating and cooling from anywhere using the app. Its traditional design covers 90% of existing thermostat on-wall footprints, so measure your current wall space before you order.

Wiring and Smart Home Setup
The thermostat offers popular smart home platform integrations. A C-wire is only required when using HomeKit, so check your wiring before you choose that option. Have a qualified technician help if you are unsure about your system's wiring.
