App is useful if you

The app is great! I did learn the hard way, it has to have a signal to communicate with the panel but due to placement of keypad and the old 2G signal plus interference. I added a panel inside of my garage and it eliminated the issue. That was 2 years ago. As of today the panel was upgraded to 4g free of charge by our Alarm company for better signal and future compatibility.
