Given that :

- We use I2C to track the charging status and detect a power failure - We set the AUTO UPS switch to ON

1 - We detect a power failure 2 - Battery is now used and everything is alright 3 - We decide to shut down the RPi 4 - During the shutdown phasis, the power is back

Q : What happens at 4? I think that actually, the RPi will just keep on shutting down normally but never powers ON again until a new power failure + power recovery cycle occurs. Which would be quite a problem and would defeat the purpose of this UPS device.
