Hi,
I habe a Samsung Family hub fridge that I connected via the SmartThings integration.
I added some automations to notify me when the fridge is open for >2min. Quite often notifications are triggered even the door is already closed. An then it still shows status as open in the dash.
Opening and closing mostly resolves the issue. It seems that sometimes but not always something gets lost along the way because the fridge itself sees the door as closed (otherwise the internal alarm of the fridge would sound). So it’s not a hardware issue of the fridge itself.
