    5.0 out of 5 stars Easy Install
    Reviewed in Canada 🇨🇦 on October 4, 2021
    I installed this today by myself. I took a pic of my old thermostat configuration to show you all. Took maybe 15 mins for everything except the WiFi. I followed the instructions on the app which was a very helpful tool. I can't say enough good things about that bc whenever I install a new thermostat I am puzzled when the letters don't matchy matchy. This app took that guesswork out for me. Thank you Emerson. The wifi I was stumped on for a but bc it said my password didn't work. I figured out either me or the app was adding a space at the end of the password... So just be aware of that. This thing works amazing. If it blows up or stops working down the road, I'll update my post but so far, so good. Both the touch screen on the device and the app work great. I love that you can lock the touch screen so your kids can't increase the temperature.

    Installed my second one in the house where I only had R W G wires. Followed tutorial on changing G to C wire and I got it up and running. Wasn't a problem. Added 10 mins onto the job. Easy peasy.

    5.0 out of 5 stars User Friendly and Intuitive
    Reviewed in Canada 🇨🇦 on November 9, 2020
    I converted from an oil to propane furnace. The oil unit used a 2 wire heating system so had to upgrade the old thermostat to a 5 wire system and a new thermostat. After initially trying the Lyric 5 and being frustrated for a week with it's lack of connectivity, i returned and picked up the Sensi. I had to find the wiring diagram online (specific for a 5 wire system) but once connected everything else was a breeze. User friendly options include customizing the heating schedule suitable for you on your smartphone, keeps connectivity, easy to navigate user controls on your smartphone. I liked that the system keeps track of the energy usage and how long the heating system was in use per day.
    I'm not a tech person, but was able to use the unit with Google Assistant. Unit blends in well with the overall aesthetic of the home.
    Would buy again
