Will not accept “hold until” setting

UPDATE: Thanks to the T5 Thermostat losing connection, and after getting it reconnected, I see the problem. If HomeKit is enabled, it will not keep the “hold until” settings. I have experimented with this numerous times today & the results are the same. If HomeKit is enabled, IT WILL NOT HOLD the new time, remove HomeKit and it works fine.
I have called Honeywell to update this & was told the thermostat is defective & to exchange it at the place of purchase. I’m sorry, but that’s a lot of trouble for something that won’t fix the issue anyway...this is an app issue, not a hardware issue. If it is a hardware issue, Honeywell has a lot of defective products out there based on the app reviews left here.
I’ve changed the rating to 1 star due to tech support telling me to go through the hassle of removing the thermostat to exchange it vs admitting there’s a problem with the app.

Original review: Everything’s seems to work (so far) except when I make a change to the temp and want to set it to hold to a specific time, or even permanently. The app will show the new time briefly, then revert back to the next scheduled setting. Sure, I can change it on the thermostat itself where it does keep the setting, but not when I’m away from home. Let me stress again, the issue is only happening when using the app (iPhone & iPad).

Great when it works

I’ve had this for probably six months now. My only complaint is that sometimes it doesn’t recognize that my wife is home. I set it to give me an alert and I keep having to turn the geofencing feature off until I get home. Aside from that quirk it is terrific.

Second complaint is data logging, or the lack thereof. It’s not a comfort issue or anything like that but I find it amazing that there’s no way to see how many hours it’s operated or in what mode and what the temperature was say every hour for at least a day or a week. At one point I set the modes too close and believe that it would heat up the house then turn on the A/C to cool it back down. With a data log feature I’d have seen that sooner.

My wife is disabled and we don’t leave the house at regular times each day so the competition’s device that “learns” your schedule was of no use to us. In theory this is a much better option however Honeywell needs to build in a data logger and definitely needs to fix the Geofencing reliability. At the very least give us a button to override the home/away and/or refreshing the search when we know for a fact that someone is home.

Terrible in all aspects!!

This thermostat was installed when we bought a new a/c about 3 months ago. On the colder nights we normally turn our heater on so that if the house temp drops to 75 or below the heater kicks on to maintain the 75 degree setting. EVERY time my husband or I do this we wake up in the middle of the night sweating!! The temperature turns up to 83!!! EVERY SINGLE TIME! The manual is useless unless you speak robot. My husband called the a/c company who installed it and they told him some directions on how to fix it, which didnt work because we couldn’t even find the buttons they told us to push on the thermostat. I downloaded the app thinking in may shed some light on the problem I am having. So I register my account, confirm my email. The app wants me to register my device by pushing the temperature on the middle of my thermostat screen for 5 seconds!! Of course this didn’t work because the thermostat is not a touch screen. I felt like a complete dolt for standing in front of the thermostat touching a screen over and over that literally did nothing.
It was like touching a computer screen from the 90’s and expecting it to actually respond!! So frustrated!!! All I want is for my children to be warm in their beds at night and Honeywell sure can’t seem to make this happen. Very frustrated!!!
