Okay, but Needs a Little Work

I replaced another brand of wi-fi thermostat with this one after the original failed. I bought the Honeywell partly because of the reviews and partly because of the company reputation. It works, but I am a little disappointed at this point. The thermostat does not update the indoor temp properly or often enough so it gets cold in the house before it turns the furnace on and then it overruns the set temperature so it gets too hot inside before the furnace turns off. I thought it was a problem with the unit so I returned it and got another. No difference. I called the support number and got someone overseas who had no idea how to understand the problem or tell me how to fix it. In addition, the unit does not have a function to give me daily unit run times. On the plus side, it is easy to set up and the display is easy to read. I would give this unit 5 stars if it would work correctly and give me some idea of how much the furnace runs on a given day.

Update, one year later. The unit has settled in as far as holding temp goes, and I like the feature where it anticipates the heat time needed to meet the temp setting at a given time. Especially useful given that we reduce the house temp to 60 degrees overnight in winter. The unit senses temp drop during the night apparently and calculates the time needed to meet the warm up time in the morning. I would give it 5 stars but there is still no function to view actual run times.

Large Two Story Home

Last year I had to replace the entire first floor HVAC system. The company providing the new HVAC system also removed my old Honeywell programmable thermostat and replaced it with another brand name thermostat. I didn’t think much about it at the time as I thought I was getting an updated thermostat. It was a horrible mistake! With two different manufactures of smart thermostats trying to adjust temperatures in the house, in short, was not working! I finally got mad and replaced both of them with these new Honeywell units. I really like the iPhone interface with both units. It is extremely easy to program and very versatile. My home is maintaining a much better comfort level while not having two HVAC units fighting for control or one not running at all. I am a little disappointed that Honeywell will not provide a common interface between the two thermostats. Ie. Both HVAC units should be running at same time so that one unit is not carrying the entire load of the home. If one unit is on, the other will not since a need to operate (at least for a little while). But, I’m not an HVAC engineer and there may be other issues here, such as a confused homeowner. Regardless, these two thermostats seem to balance my home much more effectively and efficiently than my previous set up. And the two HVAC units seem to get along with each other now. So, 5-star because they are working better than I expected!

Good functionality but still needs work

The good: I can control the thermostat remotely. It's been reliable over a couple years of use. The "air circulate" mode is very useful and helps inhibit mold and stale air. This mode circulates air about 8 hours per day even if the heat or a/c isn't on. I like that I can see system status remotely - in other words, in addition to turning it on or off, I can see if the system is actively operating at the moment.

The mediocre: The "air circulate" setting can't be customized. Also, it's not intuitive. The app interface makes it seem like I have to leave the system in heating mode (but set to 55 degrees) in the summer time if I want to use the air circulate. The app should have a dedicated setting for "air circulate" that doesn't have an apparent requirement for the system to be left in heating mode. I can't see the status of my system fan in the app when in "air circulate" mode.

The bad: There is a "marketplace" icon on the main screen which I don't need or want. This replaced the equally useless "contractor" icon which the app used to have. Now, each and every time I adjust the heat, Honeywell wants to present me an upsell. This "marketplace" should be buried in a submenu somewhere. Voice control is not implemented well and I'd prefer not to have it at all. There should be a way to disable voice control.
