5BsvCcEv I have not used planned mode as I have not updated yet, but I generally let my little SeeStar S50 go until it either runs out of batteries or the object sets. In the morning it is always shut down with the arm down. From what I understand when the battery gets too low it does this automatically.
I do agree, however, that the plan mode should include a list of options at the end of a plan. Since the software can tell it to finish plan 1 and then go to plan 2, it could certainly tell it to fold up the arm and go to sleep, just like its owner.
