Horrible

Always goes offline. No clue why? Says it’s connected to the internet,
But for some reason it says it’s offline.

This sucks

This is harassment!!!
I don’t need this!!! I am horses to take it. Heads up I am calling my Attorney on this. Who is relative. So it won’t cost me cent!!!!

Short term rental, not ideal

I was excited to see that the ElitePro S900 had a partial lock feature thinking that this would allow us to lock certain settings from our rental guests. However it only allows access to adjusting the temperature to the next scheduled time and nothing more AND locks us out on the app, only being able to remove the partial lock from the unit at the property. So we have had to leave the lock off giving our guests the ability to remove heating limits, switch the furnace off and even disable WiFi if they so wished. Very disappointing

Unusable

Like others, I got forced to use this new app and had to setup yet another account and then the new app that I just downloaded from the App Store tells me it needs an update, but you click update and there is no update. Thankfully I have my thermostat setup in Home Assistant since this is unusable.

Terrible app and now locked out

Old app on my iPhone worked just fine. New First Alert app is wasting a lot of time. Customer service after about 40 minutes seemed to fix it so I could access the thermostat on my iPhone when we finished up on October 11, 2026.

This morning the first alert app wants a 4 digit Resideo App passcode number - which was never mentioned with the help person yesterday, let along set up. So now the Resideo app is locked/ There is a message behind the locked screen that states that “you have successfully completed a migration to the First Alert app” and the rest is behind the LOCKED OUT message, so I seem to be stuck. AND I can not log out.
