Customer Ratings & Reviews

Thermostat could not accurately tell indoor temperature and would fluctuate +/- 5 degrees in 5 minutes. This would cause my emergency heat to cycle on when it was not needd. House temperature was 72 and the thermostat would read 72. A few seconds later the thermostat would read 68 and would cycle on emergency heat. After a few more seconds the indoor temp would read 73 (which was higher that the set point). I put my original thermostat back in and had no problems the indoor temperature was maintained and my heat pump system worked as expected.

It worked good on the summer but now is turning on and off now that is on Heat !! Pretty irritating and I don’t know what to do .

Not as good as the previous model. Glitchy. It gets stuck for about 10 to 15 seconds going between different settings.

This item popped up when i filtered works with Apple home kit this device however is not homekit compatible now i have to go exchange it at the last minute

The tatical response is very slow. Have to press on the same button 3 times to get a response

I wanted to upgrade but would not work with my system after 6 hoours.

Easy installation and love the compact size. Offers color customization and has a nightlight effect.

It was easy to adapt to an older system. The responsiveness of the touch screen is not great.

not easy to connect wire, very little room. they could have design it better and bigger screen, the touch screen stop working smoothly after a month or so, thank good I had square guard insurance.

Goes for long periods of time where it can't seem to connect to servers for remote functionality. Internet tests are fine and the router can communicate with the thermostat fine so it's clearly on the backend. Honeywell knows this is an issue but gives generic responses. I quick look at the reviews on the internet says this isn't isolated. If you want remote access get a different brand. Should have returned it when i had the chance.

I have bought two RTH9585s in the last couple of days. The thermometer on the first one drifted up to 78 degrees although the actual room temperature remained around 69. Then I bought another and swapped the thermostat units. On the second one, the thermometer temperature drifted down to 58 while the room remained around 69. I can only conclude that the thermometers in these thermostats are unreliable. I'm going to return both and buy something else. I'm very disappointed. Search the internet for this thermostat and you'll find that others have had bad thermometers in their units as well.

So easy to instal and download. Like the laziness it has turned me in to. Highly recommend.

DO NOT BUY! Unreal, I have paid TWO separate electricians to try and install this piece of garbage. Neither could get it to control the heat. I am actually so happy that it did not work because once it was on my wall I knew how cheap and horrible it was. The touch screen is a joke requiring one to press down as hard as they can to get it to react. Oh yes for some reason it comes with preset holds and schedule's that we were unable to clear. I honestly thought this would be a good choice rather than the NEST. Get a non smart thermostat, these things are a joke!

Honeywell used to make great products. This thermostat now runs on an iPhone app that has no functionality. The last Honeywell I had was on another app and worked great. It’s like they have let some cheap manufacturers market under Honeywell name. Would avoid it unless your certain will not be using total comfort control app

did my research and bought this. i have been using it now for a few months and love it.

Does the job. Can remotely change settings from the app. This is not a smart thermostat and will not learn your patterns.

My old thermostat had two wires, this one needed three. Returned for a refund.

It’s seems to be a good item but it’s not compatible with every kind of system

The smart thermostat is actually not smart , its just that it is connected to wifi. Looks like at the same price google nest provides much better capability. Not happy with the purchase and I was not aware that this is so basic

The specs show that the unit is 7.25 inches wide, Height is 9 inches, and Product Depth 3 inches. In reality, it is approximately 4.5 inches wide, and 3.5 inches high. I rated it one star to hopefully get someone's attention to correct the specs, but the unit is truly 5 stars. Had Geek squad install it, took 1/2 hour. Works GREAT!
