I have the myQ Garage Door app and it displays the status of the garage door (open/closed) and the number of minutes/hours the door has been open or closed.
I would like to have something similar in Hubitat, for all of my doors. At a glance I want to know how long a door has been open or closed. What would be the easiest way to do this? If it's complex to display the length of time (elapsed time) since a door was opened or closed, I would settle for just having the time of day since the door was last open or closed.
