Got my OSPi yesterday and it’s already running in place of the old sprinkler controller. Next step is to pick up some reed/contact switches and connect them to the RPi and test the code. Hopefully I’ll have that hammered out in the next couple of days. These will be initally connected to the RPi’s GPIO pins for simplicity and to avoid soldering for now.
Final step will be to add the relays – I’m considering using the RPi’s GPIO pins here too instead of the OS since I’ve used up all my stations and would need to order the OS zone expansion kit (need at least two more stations for my garage doors). However, I think it would ultimately be better to to use the OS expansion board since the software already supports controlling the doors (through HTTP commands) and the connections are easier. And that should translate to more people buying expansion boards from Ray.
