home monitor security

Instead it says alarm has been triggered and the security center has been notified. I was waiting for someone to contact me but it never happened. So I logged onto the app and found out it's a communication failure triggered by one of the sensors. I tried to disarm or reset
using the app, it wouldn't let me and kept getting message
that says cannot be reset due to the communication failure. I figured out how to reset it but I have to be home to do it using the console. Then open and close the door or window that triggered the error.
