After you select the “Choose schedule script” option, it will list all schedule scripts in the
“schedules” folder. You can choose one, and then Witty Pi 3 will take care of the rest.
If you want to confirm what the script is doing, you can check the “schedule.log” file in the
“~/wittypi” directory, when your Raspberry Pi is on.
If you want to create your own schedule script, please read the “
” chapter.

Set low voltage threshold
If you are powering your Witty Pi 3 from the XH2.54 connector, and the input voltage is lower than
the low voltage threshold, Witty Pi 3 will shutdown your Raspberry Pi. Here you can specify the low
voltage from 2.0V to 25.0V. If you want to disable the low voltage threshold, just set it to 0.
8.
Set recovery voltage threshold
If you are powering your Witty Pi 3 from the XH2.54 connector, and the input voltage is higher than
the recovery voltage threshold, Witty Pi 3 will turn on your Raspberry Pi if it was previously shut
down due to too low input voltage. Here you can specify the recovery voltage from 2.0V to 25.0V. If
you want to disable the recovery voltage threshold, just set it to 0.
Remarks:
the low voltage threshold and recovery voltage threshold can be set individually and their
combinations will make Witty Pi 3 work differently.

Witty Pi 3 doesn’t care about the input voltage changing.
Set
Not Set
Witty Pi 3 will shutdown your Raspberry Pi if input voltage is too low. It will not turn on
Raspberry Pi unless you tap the button, or the scheduled startup comes (given input
voltage is higher than low voltage threshold).
Set
Set
Witty Pi 3 will shutdown your Raspberry Pi if input voltage is too low. Once this happens,
Witty Pi 3 will monitor the input voltage during the sleep and will turn on your Raspberry
Pi when input voltage gets higher than recovery voltage threshold.
Not Set
Set
Witty Pi 3 will wake up your Raspberry Pi when input voltage is higher than recovery
voltage threshold. Please mind that if input voltage is always higher than recovery voltage
threshold, you will not be able to turn off your Raspberry Pi with these settings, because it
always turn on Raspberry Pi again just after shutting it down.
