[SOLVED] How to set battery icon values

I’m not sure what you’re trying to do now.

You already had a working Number Item, approx 2 to 3 value.
You just need to make another Number Item.
Then a rule that runs when your source Item changes, does whatever maths you want (presumably convertin to 0-100%), and posts the result to your new Item.
Put the new Item on your sitemap and ignore the source Item.

If transform profiles worked with Numbers you could do it that way instead -but they don’t, yet.

Where did you do this? Which file or which code do I have to alter? Thanks for your help.
