Template light limit maximum and minimum brightness of light

unfortunately, I’m not capable…
Thanks for all explanations

wrote one of my own, if it helps

Your Blueprint doesn’t work in my installation. No errors, but also no action. No matter how low I dim, the light stays low (too) dimmed… . Can you help? Maybe a problem of a new HA version?

I’m on the latest version of HA and it still works for me.
