I’m looking at a setup that includes a number of LED lighting strips, all powered by +5V or +12V. I am thinking the easiest way to turn them on and off would be through the GPIO pins of a Raspberry Pi. I have Home Assistant already running on a Pi, so this switcher would be a separate Pi, elsewhere in the building.
What’s the easiest way to send signals to a program on the remote Pi from Home Assistant so I can turn switches on and off?
Is there a device designed to do this already that would work with Home Assistant and be easier to use?
