Got the ospi 1.4 today – have the ospi up and running. But I still wasn’t getting my valves to turn on – still no 24 volt output on those connections. The Pi-driven web page indicated that they were on…

So. I had swapped out the Raspberry Pi itself a bit ago because it seemed to just go away occasionally – I’d have to reboot it to get it running again. Not real good for a utility sort of a thing.

But that means I still have the older Raspberry Pi. So plugged the older Raspberry Pi into the ospi board and now I’ve got water.

But I have even less idea of what to look at on the Raspberry Pi than I did on the OSPi.

Oh well.
