This is a bit embarrassingly long-winded, but by way of disclaimer: all of the players are willing participants so it's not like this is a police state up in here.
Presence in my HASS scheme is based on the Unifi controller integration, some camera motion detection and Passive Infrared (PIR) presence detectors. I intend to get into some ESP32-based 1mm radar sensors because they have better human presence detection, and are better at sensing micro-motions that indicate that 'blob' is still actually a human.
For the living room where I do have the switch on a conditional sensor, I have a Zoos 4-in-1 PIR, and a camera on the front door. Given a Human present from a PIR ping or a camera motion detect, and if the sun is below 2.5°, the lights trip on for 30 minutes. They are also on a time schedule of 6:23pm to 11:32pm localtime, because we have pets and it feels like they get depressed if the people aren't around. That same schedule turns on the radio for 45 minutes if nobody is home (based on the Unifi integration).

You did ask.
So am I...
