Smart thermostats are usually the first home automation device people purchase because they help save money on utility bills. The ROI for a smart thermostat is only a couple of years and utilities often provide rebates that shortens that period.
Most home HVAC systems work with 24-volt (low voltage) thermostats, like the Nest, Ecobee, and Honeywell.
Electric baseboard and some radiant flooring systems require line voltage (120V) thermostats.
We’ve spent a lot of time reading about and testing the various smart thermostats on the market. We recommend that most people consider the Nest or Ecobee thermostats.
If you need a line voltage thermostat, we recommend the Mysa or Stelpro thermostats.
