How to Use Bluetooth Low Energy Devices to Detect Presence

I really loved Stargate growing up as a kid, and I always loved Stargate Atlantis when they would go through the Stargate. And I sort of emulated that with home assistant. So I have Z-Wave motion sensors all over the house, and I have one sitting on my desk here at the office. As soon as I walk into a room, like the bedroom or the kitchen, the lights just turn on. That's a whole other level of nerdy right there.
