This isn’t the first time this has happened but decided to look at the log and post about it since it is annoying. Yesterday two of us left, both with phones as presence sensors. The home monitor was left disarmed. About an hour later we arrived. According to the log, the following all happened with the few same seconds. The classic app was used to open the garage, our phones “arrived” and the home monitor armed itself to away (after garage door showed open). So, when I opened the door to the house, it triggered the alarm.
I know I have nothing setup to arm or disarm the home monitor and have already double checked that fact. Does anyone else occasionally have this problem or suggestions?
