Oh that’s great news Ray! Cheers for that. I just bought a couple of OSPi boards last week, so I’m really looking forward to getting them setup. I’m yet to buy the RPis, however I went ahead and bought a couple of 24vac 1.87amp transformers. So they should do the job of powering the RPi (if I go with a 3 or 4) and a number of valves simultaneously.
