There we installed in our house when we bought it (new build). We love them. Easy to program and really like the WiFi connectivity so we can program them from anywhere.
When I leave the house the unit will disconnect and will not reconnect when I come back. I have to reprogram the system every time I use it on my phone. Was installed with my new home
The app took many attempts (with login to Honeywell site from desktop browser) to install on my phone. After a couple of weeks, the it disappears on my phone. I had to reconfigure/reinstall to bring it back. App is unstable!
Very poor scheduling compared to nest. No ability to change when things happen except for a couple times a day. Geofencing is awash with multiple parties in the house. Noah way home motion detector.
