Ordered this "used like new" for under 40 bucks yesterday and and installed it today. Installation and wifi connection took less than15 minutes. However, I did install the app in my phone before I even bought the thing to look at the installation instructions, so I knew what I was getting into. Highly recommend doing that- it asks which wires you have and will tell you if the thing is compatible with your system. I have A/C, and gas heat, and no C-wire. Common issues I see in the bad reviews seem avoidable. You may need to put your Wi-Fi router into temporary 2.4GHz mode to connect, just like you have to do with other smart devices. Once it's connected the app will say it's offline for a minute or 2 but the wifi icon on the thermostat is still visible- I think it's just a lag while your info is uploading to their server. I closed out of the app and reopened it a minute later and was good to go. Easily connected to Google home assistant and Alexa. Alexa doesn't have control features in the Alexa app like Google does I the Home app. But you can say "set the A/C to 72" and it works instantly on both. In the app it shows current indoor temp, and basic current weather condition outdoors as well as indoor humidity which was a nice surprise- I don't have a hygrometer so that's great. There are settings for the stuff people complained about here โ a setting to set a temp differential since the unit does seem to be warmer than the air, a setting to slow down or (speed up) cycling if the room temp isn't stable. There's a setting to turn off the backlight so it isn't bright at night. The thermostat interface is very basic for better or for worse. There are just 3 spots to touch on the thermostat itself, right of the display. Up and down, to set the temp, and the third, between the arrows, is the "mode" (unlabeled) signified by with three dots. Touch once to see what temp it's currently set to. Touch again and the mode will switch from heat to a/c or back. I'd just prefer to be able to touch again to go back to the current temp but instead you have to wait a moment for it to go back to default display to see that touching it again will switch modes. Minor annoyance is that you can't turn the fan on from there, which is also an inconvenience for people in the home without the app. And of course any scheduling needs to be done in the app, which is fine with me. Anyway this is long but I hope that helps someone. I'll update if it all goes to schitt lol
