I came home. I unlocked the door (which disables the alarm), opened the door. I had my hands and I was placing items on the table, so I happened to be standing 1 foot away from the alarm panel (and not having left that area) when the monitoring station called me about a buglar alarm. Here's the history:
I checked that the alarm panel showed disarmed when I entered. At no time did the alarm panel make a grace time countdown. However, the monitoring service received a burglar alarm even though my node saw no alarm and the history shows no alarm.
I'd like to investigate this and see if I can figure out what happened. If you don't mind, can you please DM your hub ID and I can check into it? Thanks!
I have the same rule set up and I tell my kiddo to make sure the keypay tri-beeps before you open the front door because just unlocking it and then opening has set off the alarm and notifed the monitoring station for me a couple times. Maybe waiting until the panel reacts would help ensure the rule is processed out.
