Keep in mind that often motion sensing isn't what someone wants... great for hallways, doorways, and transitional space where someone is expected to be moving, but not great if you're going to be sitting for a bit. Presence sensing is a little more expensive but has gotten a lot better (millimeter wave stuff), great for something like a bathroom or kitchen where you might be sitting for a while but still want the lights on.

MmWave is getting cheaper but it can still be cheaper to use a regular motion sensor combined with a door sensor. This won't work for the living room, but I've found the bee in box setup to work perfectly for the bathroom. You trigger lights on when you enter and lights off when you re open the door instead of waiting for the motion sensor cool down.
