I am just getting started with Indigo and Insteon. I have two LED table lamps, one controlled with an OutletLinc and one controlled with a LampLinc. Everything is setup and I can turn then on and off from Indigo but, when they are off, they flash on briefly every 2-3 seconds. The flash is very short, probably would't be noticeable if they were incandescent lamps.

Any idea how I can stop the flashing?

I figured it out. Looks like the load of the lamps was too low for the switches. Adding a wall wart from an unused something seems to provide enough extra load to help the lights stay off properly when off. The instructions had said something about problems with small loads, but who would have thought flashing would be the result.

Otherwise, very pleased with how easy it is to get up and running with Indigo and Infateon.

Yep, the very low current draw of some LED loads can cause issues like this, unfortunately.
