This is an extension of the included motion sensor blueprint from Home Assistant. I added another sensor for brightness to only turn on lights if is actually dark. This level can be controlled via another input. If you are looking for more details I described it in my blog post.

I am using this with Aqara motion sensors which include a brightness (lux) sensor. This blueprint also includes a condition to turn the lights on during the night (after sunset, before sunrise) regardless of the brightness but you can simply remove that if you want to. The sensors used are connected via ZHA but it should work with any other sensor too.
