Good to know.
The stuff I've read about recently tracking movements using wifi - would this need more powerful radio waves than most people use or no?
You need more power than what regular people use. You would need the signal to go through walls into your home, and then read whatever comes back out through the same walls, so it’s a lot more attenuation than you typically expect.
