> I am not sure what you mean by “Due to the lack of being able to to this in the OSPI firmware,” — if you assign a zone to the parallel group, it can run at the same time with any other zone. So if you assign all 7 zones to the Parallel group, they can all run at the same time
I think we already discussed this in another thread some time ago (EDIT: found it: https://opensprinkler.com/forums/topic/parallel-grouping-of-stations-with-2-2-0-ospi-firmware/) . The problem is that I have many other zones (sprinklers not driplines). And I need to always run the sprinkler zones not in parallel with anything else (not enough water otherwise). So, ideally I would need/wish to have a group zone where all its group valves run in parallel, but at the same time this group must be sequential with regards to all other groups/zones.
For example I want to schedule the Group of 7 to run first (all paralell), then afterwards a Group of 2 very long driplines (again all parallel), then a sprinkler zone etc. – these 3 things should run one after another.
That does not seem to be possible. So the only way I can think of is hardwiring unfortunately.
