Hi,
I'm running a WittyPi mini (1st version) since a few years without any problems. Now i bought another two WittyPi 3 mini and installed it on an Raspberry Pi 3b+ and a Raspberry Pi Zero W. After installation was done, I set up the times for startup and shutdown. But nothing happens. If I check the status of wittyPi.service I got a few errors (see below), but I'm not able to solve these. Is there a fix for this available?

It says you don't have raspi-gpio installed in the system.
Maybe try these:
sudo apt update sudo apt install raspi-gpio
If your system can not have raspi-gpio installed, maybe you need to revert to older version of Raspberry Pi OS.
Just a reminder: Witty Pi 3 Mini has been discontinued (and replaced by Witty Pi 4 Mini) since year 2022, and its software has no update since then. If the old software can not fit the new system, you need to troubleshoot it by yourself, or use older system.
Hi,
I downgraded to RaspberyPi OS Bookworm. Then I have seen that the gpio command doesn't exist. So I installed wiringPi from Github and everything seems to work fine now.
Thanks for your assistance.
