Push when Garage reopens after closing

Hello,
my Garage sometimes opens immidiatly after i closed it (due to malfunction…). I know via an ESP and an reedcontact, when its closed. So: Id like to get a push, when its closed for about one second and reopens again. Anyone an idea? (i’m new to HA…)
Thanks a lot.

You can create an Automation via the GUI that will execute a push notification based on your criteria.
