The rules that have a time limit appear under Active rules until the displayed timer runs out, or until you confirm them. If you don't confirm them, they will appear under Pending rules once the timer runs out, and the firewall will revert to the previously defined settings. If you conf...
LVGL requires an Event Loop to re-draw the screen, handle user input etc. The default Event Loop is implement in lv_utils.py which uses MicroPython Timer to schedule calls to LVGL. It also supports running the Event Loop in uasyncio if needed. Some drivers start the event loop automatically...
