    Lights Blinking

    Hello All, we have a large installation of QS and are experiencing some weird randomness that we haven't been able to solve. A number of lights in the residence will "blink" from low to high once or multiple times (completely random). The homeowner has reported lights turning off then back on, though we have yet to witness this. The blinking is preceded by a loud buzzing - sounds like it's coming from fixtures/filaments. We have spent many hours with the GC, electricians, etc. but so far can't come up with anything. All panels have been checked for loose neutrals, all LV and communication wires have been checked, etc. This problem doesn't seem to be affecting any other systems in the house except the lighting.

    I'm hoping someone may have some ideas or experienced something similar...we're at a bit of a loss and our customer is starting to get frustrated. Thanks, Dave

    Same issue... mine is only occurring in a group of 3 light switches all 3 flash at the same rate briefly and randomly. No noise coming from the lights or switches while flashing. Lights are halogen led and incandescent. The LEDs are dimmable

    Dear silvamarin,

    Thank you for the information.

    Do you know if these lights are sharing neutrals with another circuit?
    Do these halogen lamps use a low voltage transformer?
    Have the outputs of the RPMs been swapped to see if it follows the RPM or stays with the load?
