HMS Alarm went on with no trigger

At 9:16 am the alarm started the beeping count down and lucky I was home and awake to disarm the system. I checked every device I have and there were no events on any of them. Even in the home monitoring events it showed the alarm was started but it doesn’t show a triggering device.

This is unnerving because I don’t really want to deal with the police because of a false alarm and if I was sleeping I don’t think the alarm is loud enough anymore to wake me.

Well got in touch with support. I sent them logs and 3 screenshots. One possibility they said was maybe a bad battery in the hub but I am not sure why that would trigger a false alarm. Anyway I hope that doesn’t happen again
