Automation based on brightness (discuss.tchncs.de)

So, I want the following to happen, does anyone have any advice the best way to make the conditions in HA?

If it’s bright outside, close the blind and turn on the light If it’s dark outside, close the blind and turn on the light If it’s anywhere in between, keep the blind open - if it’s ‘dark enough’ turn on the light as well.

I haven’t bought any lux sensors yet. I do believe it’s a lux sensor I need. Can I make this automation with 1 (pointing outside and using that value to control both the light and blind) or would I need to have 2? (I assume, one pointing outside controlling the blind, the other in the room controlling the light?

Yeah, this is what I was thinking, though I didn’t consider that the sensor facing outwards might get a different lux value if blinds are up or down with the same cloud state. I thought they’d literally be directional, having not had one before. Thanks!
