I've wired a Shelly 1 (with the jumper switched to DC) sit between LED strips and the LED driver in order to on control my kitchen undercabinet leds. It functions fine but causes the LED driver to buzz audibly when the LEDs are off (but presumably the Shelly is still drawing some power). The drivers have always hummed a bit, but it is quite loud now.
I don't know much about electrics, but I do wonder if the Shelly is drawing beneath the LED driver minimum load
The driver is rated for 30W and outputs 12V. The LEDs are non-dimmable strips at approx 15W.
Is this expected behaviour. Any ideas what I can do about this?
