@Vaughano Fantastic! Glad it’s finally working!
In regards to the required interval setting I have also experienced this problem with setting interval to 0 and really wish it worked differently. This is true not only on the OSPi but the OpenSprinkler as well. You will notice the program preview, fortunately, also accounts for this requirement.
In regards to the station status during programs this is a bug on the OSPi that I discovered the other day but blamed my odd setup. But after you have pointed it out I am certain this is an actual bug. I will let Dan know (maker of the OSPi interval program) and we will see what happens from there.
Edit: I have also noticed the OSPi interval program won’t fire master stations in program or manual mode even with them set, but again I haven’t said anything thinking it might be my setup.
