How can I make Homey send a message to my phone if a door stays open for 5 minutes?
If door is open.
And wait for 5 minutes
And if door is still open
Then push note
But maybe it is better to do it with a counter.
If door is open.
Then start counter ‘door open’
If door is closed
Then stop counter
If counter is empty and door is still open
Then push note

The nice thing about this card is that you have the option to repeat the flow/message every x minutes until the door is closed:
