Hello,
I have two Witty Pi 4 to be used as wide input power supplies for remote Raspberry Pi 3B+, one a
My need is that they power up automatically when power is applied at the input.
To do so, as in the past, I tried to install the wittyPi application, but:
- on Bullseye lite it has issues with WiringPi 3.2 (I modified the script to 3.14) and flit (which it doesn't find)
- on Stretch i2c-tools weren't found, please see the attached file.
I have two options: find a way to get wittyPi to work or find another way to change the powerup behaviour.
Any ideas?
Thank you in advance,
Mathias

Why do you need "flit" here? As I remember Witty Pi's software doesn't use flit.
As for WiringPi 3.2 on Bullseye, the installation script installs it liket this:
wget https://github.com/WiringPi/WiringPi/releases/download/3.2/wiringpi_3.2-bullseye_armhf.deb -O wiringpi.deb
apt install -y ./wiringpi.deb
And we have tested that on Bullseye. Which issue did you referred to?
We unfortunately can not help with package missing issues. I would suggest to use Bullseye or Bookworm, Stretch may be kind of too old.

Ok, in the end I succeeded, but I would like you to know the following:
- booting a Pi 3B+ with Bullseye, powered with a Witty Pi 4 before installing the wittypi software doesn't work, the boot terminates very soon, switching off the supply. With Stretch it boots correctly, even without the wittypi software.
- therefore I booted the Pi 3B+ with Bullseye and another type of supply, installed wiringpi (which isn't mentioned on the manual). After installing wiringpi, installing wittypi worked without any problem.
- I could now set it to start automatically at power up
- ... and switch back to the Stretch SD.
I hope this is useful.
Thank you for the support.
Best regards,
Mathias
