I’m still interested in getting a slightly smaller image if possible.
However, otherwise I’ve done some work to tweak the weather station dashboard use case image out of the Raspian.
Here’s what I did to get a setup that will keep the clock synced when online, always start and keep HDMI output on (1080p50 fixed).
Comments starting with hashtag describe metalevel, those without are terminal commands or lines of code to insert in a settings file. You could automate much of this. I will clone this image for my personal projects, but have to shrink it first.
