Switchlinc dimmer causes flicker

[AFHA]

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.

The flicker issue has been reported by others.

Some had Lutron dimmers. Though Lutron was not the only one reported.

The Insteon power line signals are interfering with the Lutrons electronics.

I believe some users have added a filter to the power feed to the effected Lutron device. To keep the power line signals out of its electronics.
