You just described Scenes. You can have a bunch of preset Scenes, and use a button to pick one. Granted you can't individually adjust a particular bulb with scenes, but they are a great starting point for things like this.
- You can have a TV scene that turns on and dims certain lights when the TV comes on by watching TV power consumption or via one of the apps for TV or Roku or whatever.
- You could have a Scene that sets a bunch of lights one way when it is cloudy, and another Scene when it is sunny.
- I have a scene that turns on the garage lights, outdoor lights, front hall light, at various levels when the garage door opens.
There are dozens of other ways to use Scenes, some could be automatically triggered like my garage door, and others you could use a button, phone, Alexa, press of a light switch, or whatever to activate it.
I don't use the phone often, but it can be helpful when you don't want to be shouting to Alexa, or you aren't near your button device. I don't carry buttons around the house, they stay on their table or mounted to the walls.
You shouldn't leave your phone dead like that, you never know when you may need it. It could be a health emergency, fire, or because the spose got into a car accident.
Love dystopia. Some of my favorites are Solyent Green, 1984, Blade Runner, Logans Run, THX1138, 2001/2010, Terminator, Alien, and so on. I am sure I am missing a bunch there...
I do have an Alexa, but I use it sparingly. And I never talk about stuff near those devices that prying ears shouldn't hear.
