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?
There is a US gov weather API that I believe tells the time for sunrise and sunset, so conceivably it could be done based on time that is adjusted based on the API call. Could also take into account weather conditions. I think a light sensor would help the best although I think two sensors would be ideal (one inside) because perceived brightness can be different even when illuminance is the same outside vs inside, but maybe not enough to matter in this case.
