using several public services like Buienradar, Knmi, and a few, I decided to make my local weather station the single truth...
documentation Template - Home Assistant
however, the challenge starts with the first required option, for condition... how to make a condition outputting only those required values based on the entities my Ecowitt weather station provides.
Also, since I dont have a cloud_coverage entity nor a visibility entity, I had to find a way to template those out of my available entities on the station.
I did allow myself to add a local lux sensor (Hue outdoor) and of course the sun entity to help in day/night calculations..
Im sharing my below template, hoping you could have a look, and maybe suggest optimizations to any computation, or other thoughts you might have

I did add the buienradar forecast at first (Ive left it in comments) but decided I have those already on the actual weather.buienradar, and, since this is fully local entity, I left that out. resulting in this
