Yes I did read the docs several times. And I'm not doubting you since you
have been right every time I've asked a question haha...but I still don't
see it. From the documentation the prototype when scheduling a task is:
scheduler.queue_task(
function,
pargs=[],
pvars={},
start_time=now, #datetime
stop_time = None, #datetime
timeout = 60, #seconds
prevent_drift=False,
period=60, #seconds
immediate=False,
repeats = 1
)
I don't see anywhere a mention on how you set the group_names parameter.
