The OnOff SHIM by Pimoroni is a convenient power switch for the Raspberry Pi. The official guide suggests to install a daemon that initiates a clean shutdown on button press. A much simpler solution is to use device tree overlays and avoid 3rd-party tools.

The Raspberry Pi features a built-in hardware watchdog timer that automatically resets the system if it becomes unresponsive or freezes. This can be handy when used as an audio player like Volumio - especially if the hardware is not easy to access.
