I previously had the Honeywell app for my previous unit and then upgraded system which forced me to get an Observer thermostat.

I feel like I transported 15 years in technology between the Honeywell app and the observer app. Just wishing there was a cooler app for this product.

Product works with the thermostat well though and does what it is suppose to do.

Works pretty well

It mimics the thermostat interface. Works just fine. I do wish it updated the display a little more often, as it sometimes seems to go a few minutes without updating what I change at the wall thermostat, or the actual ac unit takes a few minutes to engage whatever change I put into the app interface. Not always, but sometimes. It really does usually work pretty well. I haven’t had any bug issues others reported.

Worst app I have EVER used

Junk interface, only updates every few days so it is worthless to use to monitor your thermostat remotely. If I try to go to the desktop site, it won’t work and tells me to use the app. Maybe it is a setting on my end but “app support” is a phone number that is only good from 8-5 MF while I am at work. Not going to help. I am considering returning the thermostat and getting a Nest I am so unhappy with it.
