I have set a schedule in the my dyson app for the the TP09. On every day at a certain time, and off by 20:45. The schedule has been switched on after adding the event in the app. However, it doesn’t turn off at the expected time? It seems to keep running, with the screen on. Does the app actually need to be running on the phone for this to work after it s set up? Where does it actually set the schedule when you do that through the app? Does the app trigger it at the required time, does it do it as a background task, does it set something on the TP09 itself so it does it.
