I setup an automation in #HomeAssistant yesterday that when you pause or turn off the TV, and the lights in the room are off, it'll turn one on so you can see in the dark room.
My wife, upon seeing it run (I didn't tell her I'd set it up), looked at me and said "I knew I was marrying a geek, but you're trying to outdo yourself".
I'm taking this as a challenge.
@slace Nice! I've had a similar setup where I dim the living room lights and turn off the kitchen/dining lights when something starts playing on the TV. It turns them all on again when I pause to get something from the fridge.
I also have a helper switch set up called "Theatre mode" that enabled/disables this behaviour for the times we don't want it. This is linked to the google minis/assistant so you can just tell it to turn on/off.
