I recently had a low battery on one of my sensors that was triggering Trouble Beeps. Similar to Edgar in the following linked post (GC2 Trouble alerts), I do not have the option in the Alarm.com app to clear the trouble beeps despite my equipment supposedly having the capability (2GIG GC2 Firmware v1.19.1). The only option I have is to silence it at night like Edgar showed.
Per this post (2gig Malfunction beep disable) it sounds like since my firmware is newer than v1.17.03 I should have this function.
