Emerson Sensi

Emerson's $130 Sensi Wi-Fi Programmable Thermostat costs less than many other smart-home models, its button interface and app are thoughtfully arranged and it works with Amazon's Alexa.

The Sensi doesn't come with algorithmic learning, remote sensors or geofencing capabilities; the thermostat hardware is on the plain side of the spectrum.

The Sensi is a solid option if you're looking for a smart thermostat upgrade that still manages to keep things simple.

Stylish design, with a bright touchscreen ; Lots of programming flexibility ; Effective use of geofencing

A little pricey compared to the direct competition ; Run-of-the-mill app ; No algorithms that can learn your occupancy patterns

Excellent and exacting temperature controls ; Battery back up ; Highly customizable temperature scheduling

Entirely reliant on user scheduling ; Boring industrial design ; No motion sensor

From the perspective of upgrading an old thermostat to something new but not overly expensive, the Sensi is a solid choice. For a around the same price, you can admittedly get the more high-tech LUX/GEO, but the Sensi offers much finer temperature...

The Emerson Sensi has an excellent mobile app and Amazon Echo support.

It doesn’t have an automatic scheduling feature.

The Emerson Sensi's three-year warranty and impressive mobile app help make it the best value for your money.
