Description
Just a simple blueprint to control a Light’s on/off state by a Door’s open/closed state. It also contains a parameter to set a minimum on time for the light for the Door closing to turn the light back off. Some examples of how/why you would set this are included below.

Examples
The blueprint contains a parameter called Light On Time, which is the time the light must be on before a door closed event will turn the light back off.
With a Light On Time of zero, you can use this to just turn on and off a light in sync with the door, which is useful for rooms like a Closet or Laundry Room. A Light On Time of around 30 seconds or greater will turn the light on when the door opens, but when the door closes it will only turn the light off if the light has been on for more than 30 seconds (or whatever Light On Time is set too). This is useful for rooms that will be occupied with one open/close of the door and unoccupied by another open/close, such a Bathroom or a Basement.
Technically, the Turn On Time only needs to be set for a few seconds (the time needed to enter a room and close the door) but higher times can prevent the automation from fighting you in unique edge cases, like entering and exiting a room quickly because you forgot something.
