@bdraco strikes again and fixed the following problems:
- If the system is loaded, we miss events because the time has already passed.
- If the doorbell is rung at the same time as motion, we don't see the ring event because the motion event obscures it.
- If the hass clock and unifi clock are out of sync, we see the wrong events. (Still recommend to ensure that unifi and hass clocks are synchronized.)
- The Doorbell is now correctly mapped as DEVICE_CLASS_OCCUPANCY.
