Very Poor

Avoid. Been using this for a year and the new update resulted in no way (that I can find) to update the schedule. How can this miss on the basics.

Version 3.0.1 update

The First Alert update to Resideo Connect was smooth as silk. I only have a Honeywell Elite Pro S1200 thermostat and it looks the same after the update. Took about 60 seconds to update. The only change I see is the APP icon.

They won’t leave it alone

They keep making changes, for absolutely no reason, zero improvement and just make it a pain to use. And now, since their great new update, my thermostat shows a current temperature, and the app shows a different current temperature. Really made this thermostat worthless at this point. Everything was just fine until they decided they needed to change the name, and how everything worked. If I could give it zero stars I would.

Thumbs down

I needed to switch from the original Resideo app to Resideo Connect. It looks like you can no longer see your schedule or edit your schedule in the app. Please bring that back.

Humidity

This app keeps notifying me about high humidity and there is no way to turn it off! We do not have a humidity setting.
