Son/off remote wifi switching

I was looking to eliminate as much noise as I could in my shack. Besides the usual noisy wall warts I found a lot of noise on 10m and 6m coming from a 4 channel Son/off remote wifi switch. I tried using ferrite to eliminate it and no luck, I tried a stand alone 12volt battery still no luck. I thought just for the heck of it I would power it up using the120vac input. Success. No more noise. Thought you guys might be interested to know that. Maybe mine is just an odd unit with a noisy internal supply.

    I use many Sonoff devices around the house and shack with no RFI issues. They are all powered by 120VAC.

    All of my switches are now powered by 120vac except one that is using 12vdc. It is the two relay model and makes no noise.
