Hi Community,

I need your help.  
I have a door contact (open = 1, closed = 0).

I would like to generate a message when the door is open for 30 minutes. If the door is closed again within 30 minutes, nothing should happen.

I've tried something with Delay and Trigger Node, but somehow it doesn't work.

Has someone an idea for me?

Greetings

Set a trigger node to send nothing, wait 30 mins then send your open msg. And reset it if it sees a 0
