TL;DR (as the kids write)- keeping a Variable for seconds of inactivity in a given room, and using a Control Page Variable Image: anybody done this?
I have been toying with room-to-room occupancy. Motion detectors are necessary, but they have limitations. Some day, I will figure out how to make a plug-in that allows devices for “rooms” in efforts to use some logic to estimate occupancy, even when motion sensors fail, or when people are very still.
In the interim, I want to have a timer/counter for each room, tracking the time since the last activity (e.g. zwave locks, doors, motion sensors, insteon button-presses, tablet use, etc).
Moreover, I want to make some icons that correspond to the time elapsed since the last room activity, with images that change similar to a heat map (e.g. red for recent activity, clear or blue for distant activity).
The implementation is do-able, albeit tedious until I figure out plugins.
My question: has anybody implemented anything similar? C4W, I recall you having an impressive amount of logic in your room occupancy detection.
Thanks!
