I bought this to replace a dumb Honeywell “Pro Series” thermostat that came with my house. It uses the same mounting system so it was as easy as turning off power, popping off the old unit and putting this one on. No switching backplates or patching holes in the drywall. Setup could have gone more smoothly, there were delays in receiving the email confirmation to set up my account. Eventually I was able to create it and get the thermostat connected. So far it is working well and is connected to Google Home. I do wish it showed both the current temperature and the settlement temperature when the unit is “asleep” but a quick tap displays all of the information. Not as fancy as some other units with color displays but the ease of installation in my situation meant this was an easy choice.

Update — I changed my rating from 3 to 5 stars. With the latest updates it’s working really well. I’d still like to have more flexibility setting schedules and hope that’ll be included in a future update.The positives:- Very easy to install. All three connected to my router with none of the issues described in many other reviews.- No problem using them with both Siri/Apple Home and Alexa/Echo.- Intuitive user interface- The iPhone app is generally reliable and intuitive (but not entirely…)Negatives:- There is only one set of four time periods per day that cover both heating and cooling. Because of variable electricity rates where the rate change happens at different times by season, we use different times for heating and cooling settings. This thermostat does not support that. I’m hoping for a software upgrade that allows the addition of more time periods.- There are occasional dropouts of connectivity with WiFi. So far they’ve re-connected on their own reasonably quickly.- The server the iPhone app connects to is occasionally unavailable and the app fails. This happens more frequently than seems reasonable.- The iPhone app does not refresh very quickly and there seems to be no way to manually refresh (by pulling down and releasing for instance). It’s hard to tell it hasn’t refreshed because it seems to behave normally. The only way I’ve found to force it to refresh is to kill and restart the app.- Occasionally I make a change on the app and it seems to accept it, but then it reverses to the original setting. There is no indication that a commanded change has or has not been accepted by the device.

It works good, especially for the price. It’s easy to read from a distance as far as the temp. It looks good on the wall.I’m pleased enough that I have ordered another to replaced my other thermostat.Hook up is a breeze but I had to resolve the C-Wire issue. I have an older system, had the C-Wire in the wall, but not connected. Had to have the HVAC guys out to connect it at the 2 units.Problems I had. Had trouble getting the app program to work. When setting up I used a custom label: Living Room and Kitchen. The App would not complete the install and no error.Fix was a simple name: LRoom. Setup was complete.Next problem was the Thermostat would constantly drop off the WiFi.The fix was changing my security settings in my wireless router. Security was set as WPA-PSK [TKIP] + WPA2-PSK [AES] changed it to WPA2-PSK [AES] problem is solved. I have no more technical issues.Took one star off because with Alexa, you can’t control the fan, and resume the program schedule. You can control the fan with Alexa if you use a 3rd party android app, IFTTT, but still not resume the program schedule.The Honeywell app will control everything.The thermostat keeps the temp constant, I would personally like an option to widen the the temp range a degree or two. Currently using heat, I have it set to 67 and the temp will not drop to 66 before it cycles. Mine seems to have a range of cycle less than a degree.

Fully satisfied
Not only is the scale accurate to the ounce but attractive and lightweight.

Best thermostat
People complain about the setup but are usually technologically illiterate. Setup was fast and easy. Longevity wise it hadn’t disconnect from the wifi by itself at all. The mobile app itself is a little buggy. If you were to change the temperature In app sometimes it changes back to what the schedule was set at by itself. Other than that, it works flawlessly with both wifi and Apple HomeKit.

Funciona con HomeKit, fácil instalación
Excelente producto, funciona muy bien e increíble relación calidad-precio, tiene muchas funcionalidades como uso con Siri, que otros productos (incluso de la misma marca) no tienen. La instalación es super fácil, si ya tienes cableado con otro termostato hay que asegurarse que tenga el cable C.Yo instale el termostato desde la calefacción y solo necesite comprar cable eléctrico que tenía 6 cables de colores dentro. Muy muy fácil de instalar.La programación también es muy fácil. Si eres de México hay que poner en país a EUA para que te permita configurarlo pero al terminar la configuración, cambiar el país a México y ya te permite poner tu dirección para que veas la temperatura exterior.Excelente compra.

Not secure, unreliable!
This product is rubbish. The wifi constantly disconnects making the device disappear from the app and from homekit. The worst problem is that the device will not accept wifi keys with special characters in it. Difficult to set up, unreliable networking. Keep clear of this guys!
