2 gig, ion plunger low battery issues

I have a low battery warning on Ion plunger. Replace battery twice and
reset panel . Still low light warning. Switch is working, I get notification opening door.

Happy to help!

I don’t see any low batteries listed for any of your door sensors currently.

There is however a low battery listed for a Z-wave door lock labeled “Patio Door” Is that the device you are seeing notifications for?
