I have the same problem. Bought another ISY, same problem. Plugged them BOTH in, and the first one fails, and whatever one I plug in second, boots OK. Weird.

The new "Pro" sensor tags have an incredible radio. I have one inside my all metal mailbox, and I can talk to it from the basestation in the house. There are a number of 1/2" holes in the bottom of the mailbox, so perhaps the signal is escaping from there?

Since there will be no load, it shouldn't matter then. It's only used for monitoring the state of the light. I don't plan on connecting the load to anything. Only the sense wire, and line in, and the common.

I was looking at this same problem. Why can't I just get a micro module (any type) and connect sense wire 1 of the micro module to the alarm light bulb (it's 120vac). Power for the micro module is readily available from the line in to the septic controller. I suspect that the sense wires draw little to no power, so this should work. I suppose I could connect the sense wire to the buzzer circuit, which would certainly have enough oompf to drive the sensor wire of the micro module. Once connected, I can just monitor the state of the module with the ISY. Since the Insteon modules are dual band, it should work even inside a metal enclosure. No batteries and no relay required.
