I'm trying to "abuse" my event screen for showing sports live results with a small pythonscript using lxml and dbus. The script parses every 5 minutes the information and updates the notification, if its already there, otherwise adds a new notification. Then the script sleeps for another 5 minutes and so on.
As long as the screen is on, it's fully functional but if the screen is off the script won't update. It seems that the jolla goes into some kind of sleep state, because when I turn the screen on, the script updates after some time.

Is it a known bug (couldn't find anything on together.jolla.com) or is there anything more to do, if I want to use dbus, when screen is off?
