With everything going in the direction of all things "smart", this has to be one of the best smart options out there. I had a very nice Honeywell 7-Day Programmable Touchscreen thermostat which worked just fine; however, there were times when I found myself away from home unexpectedly only to have my programmable thermostat heating and cooling as it was scheduled to do. Granted in the fall and early spring it's wasn't such a big deal since the unit won't cycle on as often if at all but the winter and summer months were a different issue.
Now with my new Wi-Fi Enabled Thermostat whatever comes up is handled a swipe on my mobile. My RTH9580 would be a 5-star device but there is something going on with the firmware which keeps knocking out it's ability to read the outdoor temp through the 3rd party, AccuWeather I believe and it will continue to show "Waiting for Update". Once the unit is removed from the faceplate it will reset itself but that was a one time chore for me. According to Customer Service they are in the process of correcting this issue but in the grand scheme of things it's not a big deal but it is a feature I enjoy.
Now for the pretty stuff, the slim design is very slick and the option to change or even customize the background color is over the top. I really like that I can still see the display even when in power saving mode. However, one of my favorite features is its "timer like" ability. When you change the temp, it allows you to set it to hold that temp for X amount of time or until your schedule kicks in and this feature is also available through the app. Another great feature, No More Batteries. Although I needed my electrician for the install it was well worth it.

Rated 1.0 out of 5.0 by kit151 Defective unit - no refund
Worked well for heat during winter but unable to get the air conditioner to work now. A different thermostat was installed and all works fine. Honeywell is refusing to refund my defective unit that is 5 months old. Honeywell says they will replace but I have to have a technicians report to show that. I don't need it replaced as I had to buy a new one to get the ac working, I need a refund. Not sure where to go from here. Out over $200 from what I thought was a respectable company (Honeywell)

had this thermostat for almost 2 years. It did work fine, now I'm starting to get bad readings on indoor humidity and temperature causing some problems with run times on my a/c unit.

Rated 2.0 out of 5.0 by Honeywellwifithermostat Too much $ for the quality...
Called tech support several times to resolve the issue with the thermostat not reading outside temp and humidity. Keep getting a display saying waiting for update. Did all the troubleshooting and still having the same problems.

this one does not have adjustable fan speeds like my old one. Also after 2weeks & being hooked to internet the "outside weather" still does not show. Keep getting error message that it is searching.

Does anyone have trouble with setting the temperature above 20 degrees celsisus? I try to put it above 22 and it will not go??
Other than that, I like the look, the ability to access when I am away from home! But if I can't get it to go above 22, I may need to return it!
I am saying until the bugs are worked out- I wouldn't recommend to buy.
