So many options to “automate”. What do you want them to do? It seems simple, but you already started with one thing not everyone does, “read in bed”.
What else do you want to happen? I work with robots at my day job, and they can make you toast and coffee if you want, but you have to program them to do so. You have to specify your requirements.
I don’t automate my bedroom lights yet, because it is one of the more random rooms in the house. To begin, a pressure sensor for the bed, and multiple motions would be required at least I think. I have also considered using the light switches themselves as automation to know when we were going to sleep, because I don’t think any sensor can figure that out without strapping an accelerometer to the occupants, one of which I don’t think would accept. She’s tolerant, even supportive of my hobby, but there are limits.
