Your neighbors WIFI signals are too weak to matter in this case. Even if they were strong enough, this is a receiver-transmitter setup, so it would still be impossible to do unless you connect to their network. Even then, they’d have to assume you’re the only person present between the transmitter and the receiver.

Presence detection through WIFI was already garbage enough, this one is plain unusable.

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.
