    Very Pleased!

    Works just as well as my upstairs controller that cost 5 times as much. No issues whatsoever. It was easy to install and works like it should.

    Excellent choice. Awesome connectivity and qualifies for rebates, too.

    Modern looking and intuitive setup

    I finally got a chance to replace the last classic not-so-smart thermostat in the house with this Emerson Sensi Touch Wi-Fi Programmable Thermostat that also integrates well with Alexa which I have in almost every room. I also tested it with one Google Assistant and with the Samsung SmartThings on my Galaxy S21 Ultra phone. But I’m getting ahead of myself a bit. The installation instructions are detailed and easy to follow and execute. All you need is a screwdriver and a smartphone. Once you get the Sensi app installed and create an account, you’re ready to perform the physical install. Make sure you take note of the wires connected to your old thermostat and label them before you disconnect them. If your system does not have a C-wire, you’ll have to purchase an additional kit that will provide 24V common power to the Sensi Touch Thermostat. Once it’s installed and powered on, you’ll be able to connect to your home Wi-Fi network using the App. The Sensi Touch thermostat has a large rectangular touch display that almost looks like a smart phone in landscape mode. The temperature is displayed in very large font sizes, so you can easily see it from a fair distance. The backlit color is orange when in heating mode and a cool blue when the air conditioning is on. It offers flexible programming ranges that will satisfy everyone’s preference such as 24 hour, 7-days, 5-1-1 day, 5-2 day. Additionally, the App can track usage statistics, HVAC maintenance monitoring, alerts and reminders which will help you save money on your energy bills. Aside from all the similar features, tf you prefer the rectangular, big display look over the more round look of the competition, and if you don't need remote temp sensors in other rooms, then the Emerson Sensi Touch Smart Thermostat is a more affordable option that works well for less.
