I´m totally new to Node Red.
I´m trying to make a flow that unlocks my door when I arrive to my house based on my location.
It works really good but now I´m trying to add other family members to the flow.
The unlock part calls some cloud APIs to unlock the door. My problem is I don´t want the flow to start sending multiple API requests if more then one family member arrives at the same time.
What function can I use to block the flow from countinuing if it´s already triggered/running from other family member?
Hope it´s understandable
