I'm using my pi to power several relays. A total of ~20 relays (a 8-relay board and three 4-relay boards)
I'm also running home-assistant
Yesterday i noticed that when i try to power them all up, some don't work. If i switch some off, then switch others on they work.
I am powering all the relay boards out of one 5v pin. Could that be the issue?
Mainly the question is, are the two 5v pin on the same rail? should i switch some relays over to the other 5v pin to balance them out or is something else the issue?
