Hi
I am using Witty Pi 4 together with Raspberry Pi4 in a project in order to power it down in a controlled manner. At the moment I am not using any of the scheduling possibilities but the RTC functions are useful as the PI gathers data and put it into an Influx database.
My question is:
Is it possible to add a delay when the user pushes the power button to turn the device off? So that the user does not turn it off by accident, but has to push and hold the button for 3 seconds before the unit shuts down?
Would be great if anyone could put me in the right direction 🙂

You will need to modify the software (and maybe also the firmware) to achieve this.
Some customers already tried this on Witty Pi 3: https://github.com/uugear/Witty-Pi-3/pull/7
You can do the same on Witty Pi 4. However it is better to also modify the firmware accordingly, because when the button is clicked, the firmware already mark the state as "turning off" immediately, I am not sure if that will cause some unexpected behavior if Raspberry Pi doesn't shutdown and continue to work.

Thanks for the quick response to my question. We will have a look and check if we can use this approach.
