Currently I have my openHAB running on an RPi4, and as I’m using some legacy 1.x bindings, I have to use another one for those in parallel.
I also have some Pis running for other purposes (multiroom audio, etc.), so I was wondering if there is some decent enough powersource to power all those devices? I searched up and down, and I came only across some 2.4A USB hubs or power cables - but noone offers more than one 3A+ USB-Port for loading…
Am I just blind? or do I have to use a bunch of single-3A power sources (which should have significant lower efficiency as one “big” one?), I imagine?
Someone out there also using a cluster of Pis with a good power solution for that?
