I have been using Insteon products for some time, but this is a first home with extensive use and first time with an ISY. I have ended up using 3 of the micro dimmers to control lights where it was the only option. Everything is working, however the lights that are connected to the micro dimmers flicker when there is Insteon Traffic. This can be another room turning a light on/off, or programming scenes on the ISY. The more the light is dimmed, the more noticeable the flicker is. For troubleshooting we have turned off all other breakers in the house and the problem is still exhibited. They do not flicker if no other insteon device is touched.
