It's actually pretty easy to see if someone is using WiFi to monitor a building. The hard part is nailing down exactly where they are if it's not inside your building.

It’s pretty hard if they’re only listening to your wifi strength and not emitting themself.

Except for the whole drones being controlled by what's basically WiFi, they use 2.4 and 5ghz frequencies for that and it will be actively transmitting.

As I said, I’m not talking about the technology in the article. That’s an entirely different use case.
Also autonomous drones don’t need to emit wifi. But you wouldn’t fly a drone around a building to covertly monitor personnel. Drones aren’t very subtle.
