Don't thank me too soon 😀

It turns out, it doesn't work reliable!?

I'm calling it with the following python code

v = subprocess.run(["/usr/bin/bash", "witty_voltage.sh"], capture_output=True, text=True).stdout.strip()
voltage = v + " Volt"
return voltage

Sometimes it returns "0 Volt" sometimes " Volt" sometimes "13.11 Volt".
Maybe someone can help me out!?

Got it working. And added a "read scheduled startup" script too 🙂
