Make sure you have the MAC address written down, especially if you have another thermostat of the same kind it may recognize the first one instead of the second. Eventually, I was able to set up the second thermostat it may have just taken a while To recognize the new one.

I just switched to this app from the old Resideo app. First thing I notice is that any music I have playing will stop when opening this app. That is not needed when I only use this app for my thermostat. I play music with YouTube music with a subscription. I don’t see a way to change the thermostat schedule for sleep after initially setting up the schedule. This app also doesn’t integrate with Samsung SmartThings like the old Resideo app did, so my automations no longer work. Another issue is that I notice the location icon at the top of my screen will start appearing every 20 seconds. It stops when I force close the app. Checking the location every 20 seconds can’t help the battery life. Response to updated developer feedback: The video link shows how to setup a schedule initially. It does not show how to change it. Not only a useless response, but a waste of my time. Update 12/6/25 My geofencing schedule just complete disappeared. No notice or anything. Just noticed my house was cold, so I checked the thermostat and it was on a time based schedule. The app showed no auto-away schedule existed.

Apps seems to have no settings to show in Celsius, even if my thermostats are in Celsius.

This app needlessly demands location information in order to set up. It makes the questionable claim that location services are required to add a device. Gross.

FocusPro S200 time is off one hour. I live in central time, but internet pulled time shown on thermostat is ahead one hour in eastern time. Internet pulled weather (accuweather) is not local, shows weather some place else.

Really provides easy access and controllability to many home items from one app. Simple and straight froward to install, setup, and use.

Totally a case of a supplier creating an app to force an invasive relationship with its consumers. Beyond initial set up of devices, it provides zero value. There’s absolutely no reason their products should not be able to integrate directly with HomeKit or Google Home. Like many, I’m here because the excellent Nest Protect smoke detectors are reaching end of life. And First Alert provides the “replacement.” Unfortunately, users are saddled with a buggy app that is only good for setting up integrations with other services. The app itself appears incapable of remaining linked with the devices it’s supposed to manage. (No, no, you dumb app, I’m not resetting my three new devices again.) And it is absolutely catastrophic on maintaining Wi-Fi connections. Junk.
