If I could take away stars, I would. But I cant, so you get a 1. When you go to connect the thermostat to a network it only shows the first result, which is almost never your network. It's 100% unusable garbage and why Johnson Controls thinks they have any business making thermostats or software is beyond me. This is on a Pixel 6 Pro so if it doesn't work on my phone it doesn't work on anyone's phone. Google needs to remove this garbage from it's store, it does not meet standards.

11/30/23... Why isn't the issue getting fixed?????????????????Still Disconnecting where batteries have to be reinstalled. Worst app! Please fix the issue !!!!!! Just installed new batteries in the thermostat after many more disconnecting issues. Works for a very short time before disconnecting again. Still disconnects even after uninstalling and re installing app. Reoccurring problem way to often for no good reason. I have to keep taking batteries out and resetting.

This is probably the worst mobile software application I've ever used. The scheduling interface DOES NOT WORK. It does not save the settings and there is no place in the app to tell it to set Schedule to ON. The whole user interface is horrible and confusing. The previous app was bad but this new version is effectively unusable. Please, please just release a simple app allowing customers to set a schedule in an easy way. It's the only essential thing a "smart" thermostat needs to do.
