    Hi guys,

    as in the subject, is there an easy way to check if LEDS are in use?
    I'm thinking about adding a relay that would switch off my power supply when LEDS are not used.

    This relay would be controlled by RPi GPIO by a python script, that would be checking whether there is any "action" on LEDS for more than 5 seconds. If not then switch off PSU.

    Is this even possible?

    Right now when there is low power consumption, my PSU generates noticeable noise which sometimes is quite annoying :/
