Theme files are uncompressed zip files. I added shutter themes to the tutorial a second ago, sorry for the delay...
How to make a theme?
For a binary theme called
sensor.theme, you need to create two files with the same dimensions:
and zip those into sensor.theme (disable compression!).
Make sure you don't put a directory inside zip file!
How it works?
For any channel value, it chooses image with matching range. If current value is larger than largest end, the last item is used instead.
For lights etc we typically create 5 images, for example inside
light.theme you will found:
Code: Alles auswählen
light_0_0.png
light_1_29.png
light_30_59.png
light_60_89.png
light_90_100.png
We kind of forgot to put that into documentation, it will be fixed soon.
