App needs more QA

As several others have mentioned, if you have multiple zones, the UII will spontaneously jump back to the first thermostat in your list.

The + and - temp buttons on all secondary zones don’t work. Instead it displays 0 as the new desired temp.

You are forced to carefully use an analog simulated wheel to make the temp change and if you don’t perfectly select the wheel, the ui will panic and scroll back all the way to the first thermostat.

There’s also the caching problem, where it lies to you. Sometimes, you can make changes and it throws them away. So, be sure to go back and check a few minutes later.

Somewhat related to the caching problem, the system will not allow you to leave the fan running all the time. Well the UI will tell you that it’s set to on, but as soon as your next scheduled event occurs, it takes over the fan again and sets it to auto.

So, if you want to follow the guidance of your HVAC installer and leave the fan running 24/7, you can’t use schedules.

There’s no way any executive at the company uses this app. I wonder whose HVAC system they use, I should switch to one that works.

Just how do you get help? I can run the thermostat if I log into safari on my phone but I can’t log into the app! Called the number to talk to someone, they had to give me another number. That person had no idea how to help me. Don’t you have a software tech? I was told to call my installer. Are you kidding? It’s your app. And don’t tell me to uninstall the app. The app already has all my info from when I registered. You can’t permanently uninstall an app. When you install it again it brings back all the previous information. I have tried it a dozen times. I have tried changing my password a dozen times or more. Who can help me???

Poorly Designed & Maintained App

The app is just about useless. Trying to get into settings for any thermostat other than the first one listed is impossible, the app just cycles back to the first unit listed and there is no way to change the order of thermostats. Second the app is just not responsive to anything you put in. Developers need to get it working or replace our thermostats with something that works and quit selling homeowners on a product that does not work.
