Has anything been done to address this? The suggested solution in that thread is definitely not a solution. Maybe I could write something in rule machine to fix this? I need the motion in my garage to run on a delay so we can disarm the alarm when we get home.
Honestly this is a fairly niche use case. Generally when motion sensors are used for security they are monitoring a internal space and as such would be immediately triggered since the perimeter has been breached. I would suggest using a door sensor on the garage door instead.
@mavrrick58's suggestion makes the most sense. However, if there is some odd reason that doesn't work for you, a quick and dirty solution might be to create a virtual contact sensor and write a really quick and easy RM rule that opens or closes it based on the motion sensor becoming active or going inactive,
You can set up the delays I have mine set for both armed at home and armed away. Scroll all the way to the bottom of your HSM app and you will see configure arming / disarming/cancel options and you will find it in there
