This sounds like a good idea. We would love to share this in more detail with the other users as an example with the EZIO2X4 if you would be willing to share how it worked when you are done. Let us know how things work for you.
1. Is the logic on the EZIO2X4 correct to do this? There is an example with a magnetic contact that suggests it is but the description of the inputs seems to contradict that and suggest that the light will go off when the detector alarms and on when it clears. Can someone tell me for sure which way the inputs work?
The logic on the EZIO2X4 will work. The way it works is a logic low will set the input status to ON, a logic high the input status is OFF. You can then use our utility to map an Insteon command (say to turn on a light) to an input state. So, you can map Input State of OFF to an Insteon command of Cmd1 11 Cmd2 FF, turning on a light.
2. The EZIO2X4 has a programmable OFF delay which is nice but it is not clear if it resets if the input goes back to ON before it times out. I assume if the motion trigger was activitated again before the timeout that the light would just stay on but was wondering if anybody can confirm that?
Each time the input is set, the timer is reset on each transition. If it was activated again during the delay period, the delay period will reset.
