Fridge / Frezer Door Alarm

[free30]

I'd like to use an inexpensive door sensor to work as a 'Fridge Door Alarm'.

Is there anyway to have an event trigged if a device is 'On' of a set amount of time?

Maybe I need more than one event and a pro account.......
The doors opens and sends an on signal,
than that triggers a dummy device to turn on with a delay.
The the dummy device could trigger an event with the condition of the first switch still being open (on).

Is there an easier way?
I can't pay long turn for a pro account so another way, even if it means buying hardware now would be great.

Was this time delay trigger ever solved?
I would like a alarm to go off if the front door is left open for more than 5 mins if the outside temp is below -5!

I'm doing the same with a Nexa LMST-606 magnet switch.

I can set it up to trigger if the door is open for sometime, but can't think how to cancel the event if the door is closed before the on trigger.

hmmm...
