Inspired by Scott Hanselmans wall mounted Family Calendar I installed a monitor with an attached Raspberry Pi Zero W 2 years back and been experimenting with various technical approaches to host the web page for this family board. Currently it is Blazor WebAssembly. This app occasionally breaks or has to recover from a wireless connection loss. Surely I will invest some time in the future to get down to the actual root cause of the problem, but until then I wanted to have a more or less intelligent way of refreshing when the kiosk app breaks. Based on this StackOverflow post I created this Python script evalimage. As my family board has a black background I assume when the most present color is not black, it is broken. When assumed broken it exits with error level 1. Not to forget that the growing log file needs to be kept in check. You may use and extend these scripts from my repo by just cloning it to your pi users home.
