I would like to have a constant alert sound through a ring chime when ever a specific door is open.  Open the door, the alert starts, close the door it stops.  So when ever the door is open you can hear the alert.  I already have the ring alarm and all the sensors, I just want to know when a specific door is open.  Not just once when it opens, but the whole time it is open.  Since it is just software I could see some people want only if the door was left open for 5 minutes, or what ever.  You could make this quite flexible for most needs.
