Amazon offers the Emerson Sensi Wi-Fi Smart Programmable Thermostat (Pro Version) for $85.42 with free shipping. That’s nearly $75 below list, about $25 less than the typical going rate and the best price we’ve ever seen. It features wireless connectivity, iOS/Android mobile app support, custom 7 day scheduling, Amazon Echo compatibility and do-it-yourself installation. This thermostat is just about as smart as Nest, but costs a heck of a lot less. Rated 4.4 out of 5 stars from 1,281 Amazon reviewers.

When we set out to design a Wi-Fi solution, compatibility was our top priority. We think you’ll agree, a Wi-Fi thermostat that does not require a common wire and uses 2 standard AA batteries is a solution you can install with complete confidence. That’s why we designed the Sensi thermostat to work with the existing wiring on gas, oil, geothermal, heat pump and radiant heat systems – up to 4 stages of heating and 2 stages of cooling. A common wire is only required on 2-wire heat-only or AC-only systems.
