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?

Can't you just use time as an input? That's how I control the brightness of my lights

I considered this, but I want it based on outside brightness, as it affects glare in the room. I’d like the blind to be open if at all possible, i.e. when it’s duller outside.
