Thanks for all the ideas about intermediate board between pine64 and relay. However i still don't follow why would it prevent triggering relay on power on, that intermediate board that controls relay will be powered on at some point as well and it will trigger that relay once it is powered on, right ?
I noticed that on power on, it is really a fraction of second when the relay gets power (blip), so i wonder if there is
an inexpensive electronic component that will only pass signal if powered more than a ( 1 or 1/2) second, because on boot it is just the matter pf fraction of second when the relay gets power blip, if only i can skip/ignore that blip then the rest will just work.
another option comes to mind, using battery powered pine64 all the time, and keep charging battery whenever wire power present (most of the time) that should help to avoid blips.
