Thanks. I'll see if I can dig up a resistor. Where would it go on the circuit? I'm using 12+ and sig on the controller. Would it bridge those at the controller? So, this issue isn't quite as cut and dry as I thought. I came into the kitchen this morning, the can lights turn on because of the motion sensor and the test light for the doorbell goes on with it!!!!! :o Surely mistaken, I turned the can lights off, doorbell light went off. Dimmed them up past 10% and the doorbell light would trigger a press and hold it until I turn off the cans. I turned the can lights on and off a few times just to make sure that I'm not crazy. And the doorbell test light would go on anytime the can lights were on. The doorbell test light is in a different room...not related in any way to my kitchen programming. Late last night when I wrote the reply, the cans were never on, since the motion programming turns on an 'evening' scene instead at night. My Elk & doorbell are high on a cabinet in the kitchen, about 4ft from a 75w halogen can light. The Elk has been just sitting out in the open while I get this figured out. So, I turn the can lights on, doorbell press triggers and holds. I go up to the Elk and put my hand over it to block the light (not touching) and the doorbell release event fires. Move my hand, the doorbell presses and holds again. I took a scrap piece of opaque plastic and covered the Elk and left it for now. Now it's acting correctly, can lights on or off. Could the Elk be light sensitive? Or is this setup so sensitive without a resistor that a nearby can light or halogen could trigger the contact via some sort of interference?
