The OSPi program deviated from the OpenSprinkler Arduino firmware by introducing a concept of single vs repeating programs. This concept is not understood by the app and therefore causes this issue. I have mentioned it to Dan a while back but due to other pressing issues it hasn’t been resolved.
I will take a look at it now and see if I can figure it out, thanks!
