I have one Switchlinc 2477D dimmer, an ISY994i, and a PLM. My bedroom is right next to the bathroom. Both the rooms have their own switches. The dimmer 2477D controls the bedroom lights; a regular dimmer switch (Lutron) controls the bathroom lights . When I turn on or off the 2477D, the bedroom lights work as expected - however, the *bathroom* lights flicker significantly. The flickering occurs if irrespective of whether I use the ISY994i or the 2477D switch directly. Any theories on why this happens? Before the installation of 2477D, there were no flicker issues. I don't have any other Insteon devices in the house - just the one 2477D.
