I got some Insteon Motion sensors and am having the strangest problems.
1) After linking the first motion sensor with the ISY, I made a little test program that would be activated by the sensor. I set the Insteon -> Control(not status) so that I'd get an on trigger whenever there was motion. I disabled the jumper to do the countdown. The program was never triggered. The status of the sensor always showed on. Whenever there was motion and the red led would blink, the access point that it was next to would not also blink. However, if I pressed the set button on the back, it would blink and the status would toggle from on to off and visa versa. So it appears that the Insteon Motion sensors have a bug where they only ever send the on the first time if the disable countdown jumper is set and it never sends an on again.
2) The dusk/dawn status is blank. It doesn't show on or off ever.
3) The low battery warning status is blank. It also doesn't show on or off.
Perhaps 2 & 3 or control only? Except that a program that triggers on the control, and not status of the dusk/dawn sensor is not triggered by me putting my hand in front of the sensor to block out the light..
4) Next I disabled the test program and linked the motion sensor into a scene that only has one light in it. The motion sensor is the controller. The linking fails every time no matter how many times I try it. The sensor is right next to the AP and the AP is plugged into the same socket as the ISY. However, even though the linking failed, pressing the set button on the sensor toggles the light on and off. How strange, the ISY does not show any links in this particular light to be managed by the sensor.
Next I did a remove on the motion sensor. Got it removed and the sensor no longer shows up in the list. However pressing the set button still toggles the light on and off.
Next I did a restore of the one light that was being controlled. After it succeeded, pressing the set button on the motion sensor *still* toggles the light! The only way that I was able to get rid of the link is by factory resetting the switchlink and then doing a restore.
So it appears that Restore Device doesn't remove links that the ISY doesn't already know about. In this case, the linik was added by the ISY but since comm failed to the motion sensor for some reason, the the link that was successfully added to the switchlink does not show up on the ISYs list.
