Something you might want to test in the lab. I scheduled a few zones to run manually for a minute each. I then stopped the first one while it was running, and the following jobs in the queue didn’t start. I had to stop them all and resubmit. Running OSPi unified latest. Let me know if you need more details. Thanks!
If you notice, the queued stations will show a scheduled start time. When you stop a station, the queue does not get moved up and therefore the next station will start at its scheduled time (which is after the first station turns off regardless if it is actually on or off).
