I’ve had a Honeywell thermostat for three years, and until this week I’ve suffered through MULTIPLE issues that arise CONSTANTLY. If you’re looking for a WiFi thermostat stay as far away from Honeywell as possible. Customer service hours are very limited, which when you’re thermostat is out at 3AM, for the third time this month and it’s 18 degreees out, know that there will be no one to help you, period. But also know that you’ll regularly lose the connection between app and thermostat, and you have to set it up again as if it’s a new thermostat, which takes close to 10 minutes, and sometimes it won’t connect without reaching out to customer service and getting help with a hard reset. I can’t tell you all what a mess this thermostat, app, and company customer service is in a reasonable amount of time, but I can say I have another house with a competitor thermostat and in the three years I’ve also had that one I’ve NEVER had one issue! My Honeywell has issues on a monthly basis. BUYER BEWARE!!!!!!! UPDATE: the app will now just not work. I have been using it with continued random issues, but now when the app opens it just gets stuck on the page with the Honeywell opening screen (hallway table and backpack with the name) and won’t do anything, deleting and reinstalling doesn’t help. I’ve literally never come across such a bad performing app and system.

TL;DR: Keep the old app, Total Connect. Too much of a delay; massive headache. iPhone 13 Pro: Compared to the Total Connect app, this is a huge downgrade. Weather takes forever to update on the main page but my biggest gripe with the app is that it is VERY slow to update and respond to thermostat changes. For example, when I open the app, it will be stuck on the last known settings (mode, temp, etc) - even if the settings are outdated (e.g., I changed the temp on the screen since I last used the app or someone else changed them on the app). If I change the settings at that point and then close the app, no changes will be registered (even thought the app temporarily reflects the change). Instead, I have to open the app, click into one of the thermostats, go back to home, minimize the app and continuously navigate back to the app until I see the settings update. At that point I can finally make a change and it's a >50% chance that the change will successfully apply. It's a guessing game if I don't know what the current settings are. Instead, I went back to the TC app which updates immediately and shows the settings in real time. Hopefully, they don't fully retire the TC app. Otherwise, there are plenty of other smart home devices to choose from.

The app is fine, when it actually works. However, it is constantly disconnecting from the WiFi (multiple times a day). It only seems to remain connected to the WiFi when my phone is connected to the same WiFi. Now imagine if you have an upstairs and downstairs thermostat, with corresponding WiFi’s. Even if you try to access the system from home, one of them will always show as offline because you can’t be on two WiFi’s at once. Do I need to get into accessing it remotely, if I can’t even access it from home?? In addition, it has so many bugs. I will go in and change a temperature setting and the app reverts right back to where it was. For example: My thermostat is off, I will go in and turn the heat on via the app. The screen will allow me to change it and then seconds later, reverse it back to off, as if I never turned it on. Lastly, it will sometimes completely drop one or both of the thermostats from the app. The whole point of this app was the be able to control the thermostat remotely. If I have to be at home on the WiFi to access it, there’s no point. If I have to go directly to the thermostat to update it because the app is undoing my selections, again there is no point to this. It feels like such a waste of time and money. I regret this purchase.
