I have installed four Lutron MACL-153M-WH Maestro 150-Watt Multi-Location CFL/LED Digital Dimmer with companion dimmers around the house. Three of them are on one circuit (#2) and the forth on another (#18). If any of the lights are turned "on" for circuit #2, and I turn the light "on" or "off" circuit #18 from the master or any companion dimmers; the lights on circuit #2 blink "off/on" once. I noticed the master dimmer switch LED indicator powers down on the indicator lights and immediately back up to the preset dim level.
The lights on #2 are all LED. The light on #18 are CFL.
What would be causing lights on different circuits to do this? Everything works fine on the individual circuits and there are no other observable issues with the dimmers/lights.
