At the absolute worse time, 12:30 AM, the sound of the siren woke me up. I walked through the house and there was nothing that triggered the alarm. Actually, the alarm was not even enabled. Trying to stop the Siren through the SmartThings app did nothing. When I went to the board panel I heard a loud hissing noise and the red light on the board was on. I disconnected the power and plugged back in, and the same happened after a few seconds. I had to leave it disconnected. Any advice or action, has anyone seen this before?
