120v to DC 24v LED lights. PIR sensor cause buzz

[Toolfreaky]

I changed to undercabiner lights to DC 24v with a DC24v dimmable controller, and also added a PIR sensor Everything works great but after adding the PIR, the PIR will buzz when I dim the lights. It does not buzz if no PIR is used or if not dimmed at the light switch. Light switch is also for LED dimming. Anyone have any solutions?

Seems to me the PIR is not compatible with the dimmer.

You can pick one or the other or get an 120V PIR and place it before the dimmer and power supply.
