I have a 2420M motion sensor that I use outdoors to monitor motion on my back patio. It works great, but I'd like to extend it use by having it sense low light situations, such as dark clouds that may make it look like dust hours before it's dusk. My goal is to have motion enable the back patio lights to turn on if it's after dusk or somewhat dark during the day.
My question is, I have created a trigger that should activate on sensing a "Group 2" from the motion detector. However, the 2420M never seems to send an Insteon command "Group 2" saying it's detected "dark". I know there is a jumper to set it to only activate at night, but that's not what I want it to do. I am trying to make the 2420M into a day/night sensor as well as a motion detector.
Am I asking too much of this device? If so, that's OK. I just want to know how much I can expect.
