Terrible
The app is finicky, most of the time it doesnt work, and no notification to tell you when it is working and when not. If controlling your alarm system remotely is important to you, this is not the product to buy. I have tried now for 4 years to sort this out. The company does not respond to your query, even the installer is complaining as there is very little support for them.
