I hate those. They always turn off when I'm in the room. Then I'm waving my arms around every 15 minutes and it's more of a pain than just switching on the lights as I enter a room.

That's also used at offices to encourage workers to leave at night. Why are you here at 8pm? Let's switch off the lights every 5 min unless you get up and wave your hands.

These days you can get mmwave presence sensors which don't have the same issues motion sensors do.

  Mmwave stuff is really expensive still, I'm waiting for them to come down to sane prices first. Top 2 would be bedroom presence (don't do stuff if someone is in the bedroom, but sleeping, can't do that with IR) and living room presence (If I'm on the couch, don't turn off stuff, I might need it).

    Not sure of the quality but I am seeing Chinese-made mmWave presence sensors for sale for 30-45$/unit.
