    Easy set up if your hvac wires are in order, specially the C wire. If not, it may take some time to figure out what goes where. I have the blue C wire, but it wasn't properly connect and it took me a few hours to figure out where to connect it for power. Other than that, pretty straight forward. Had a little issue adding device to home. When setting up in app, make sure you choose only the wires that's connected. App is fairly simple to use. Only problem I had was the auto setting is a bit confusing. There's no one temperature to set at, There's a range between heating and cooling you have to set and it doesn't keep a constant temperature. It fluctuates a few degrees. When installing, decide if you want to use the back plate or not before you connect the wires. Otherwise, you'll have to disconnect them to add the plate. Annoying at first to connect, but works as it design to. Now, you can control your thermostat from anywhere. Not a fan of the oval shape, but already had a few Cync device and app. Suppoort respond fairly quickly, but hand you from one tech to the next that doesn't seem to understand your specific issue before giving an answer. You'd be better of figuring it out yourself.

    Configuration without wifi is the only reason for 4 star review. Initially I had no internet when installing this thermostat and the paperwork with the thermostat did not mention the setup menu from what I could find. I really like the functionality and even bought a second thermostat for my other unit. The app makes setup simple and under normal circumstances would be outstanding. Thermostat is a small frame so expect some touchup paint around the thermostat

    Need More Quality Control

    I loved this thermostat, but unfortunately I’m getting my refund on this as soon as I get a replacement. Setup was easy and it runs great, but after two days the screen started falling off and won’t stay on. No one else has this in stock and I don’t have a week to go without a thermostat when it’s 95 degrees here everyday. They need to improve their quality control.

    Smart thermostat with some dumb logic

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    As smart thermostats go, this one does well enough, but requires learning some of its quirks. I chose this one mainly because I also have Cync lights and a Savant system in the house, so I wanted to keep with the ecosystem, but that not being a factor I'd have probably chosen something else. Some of the quirks include that you can't set a specific "heat" and "cool" temperature, you have to choose a range for heat and cool to kick on (ex. a 4 degree range between 69 and 73, but if you drop the cool to 72, the heat will drop to 68). I imagine this is done to prevent the range from being too tight to prevent AC/heating from kick on back and forth, but there's better ways to implement that prevention. It also has a 1 degree "buffer" that can't be turned off, so if you're set to cool at 73 but the temperature is reading 74, the AC won't actually kick on until 75. This is probably my biggest complaint as it makes the AC work harder trying to get it back down 2 degrees vs 1, makes the house hotter than I actually want, and if I want to manually kick the AC on I have to turn it down lower than I actually want. The scheduling in the Cync app is also frustratingly confusion in how to set. I eventually got it, but again, just needlessly poor UX design.

    Had a Best Buy third party service provider intall this thermostat (1of2) and so far I’ve been toying around getting use to it and the app as this is the very first one I’ve ever bought and I can tell you that it’s been phenomenal especially with the heatwave that’s going on. It’s easy to use plus I love the fact I can change the temperature of my house away from home. I do recommend this product

    Main reason I decided to purchase this thermostat over the other ones was that it included the trim plate. Plate is a little oversized which is perfect to cover the outline of my old one. There is 2 things I didn't like, "didn't like that I have to use the app to set the schedules". Don't like that it doesn't display the time like my previous thermostat. Besides that it's a nice thermostat.
