I have a customer who recently purchased a house that has a Homeworks interactive system in it. He has found that his kids like to leave lights on through out the house and i was tasked with setting up some kind of timer for the lights that the kids use so that the lights will turn off automatically. I was able to get a delay set up for the rooms that have keypads, but i am having issues with three of the rooms. These rooms only have HWV-600D and HWV-1000NS in them. I was wondering if there is any way to set them up so they will automatically turn off after a set period of time? I get the feeling that it is impossible without some sort of Vacancy/Occupancy sensor, but i thought i would ask to see if anyone has any ideas. Any help would be appreciated.
