Thanks for the note. That’s good info to help configuring the Kraken as part of a system.
Because there are no user-accessible controls on the Kraken or the Pi, I wanted to be able to tuck the two devices out of sight and power them up/down remotely. Knowing this, now I just need a switch. Misunderstanding the initial advice, I was thinking that I’d need some sort of time-delay relay to turn things on in sequence.
Thanks for clarifying (and simplifying) things.
