The nice thing of intrusive sensors that sense things that are not sensed by your usual senses, like this, is that it's easy to saturate them while faking innocence. I.e., set up your laptop so that it does many scans and/or associations to the local WiFi, and then some light internet activity (the usual suspects: WhatsApp, Facebook, etc). The detector triggers, the landlord shows up to check what's going on, you show it's just you and your partner. Do that a few times until the landlord is convinced that the sensor is malfunctioning; unless they are IT technicals themselves, which I guess won't happen often, they will have a hard time understanding what's really going on, even more to prove it.

what's the end goal? To convince the owner that the occupancy counter is malfunctioning for a couple days and then after that throw a big party? Maybe you can just ask if it's okay to host a party before renting..

Whose end goal? The tenant's goal might be, as you say, to convince the landlord that the device is unreliable, and cheat on the rent agreement. If you want to cheat, as I guess some people do (otherwise there wouldn't be need for a monitor), asking if it's ok to host a party isn't a good solution.

My personal end goal is speculation. Each time a technology is discussed it's pretty automatic for me to think about what are its weaknesses and strengths, and how its behavior can be subverted or the same thing can be used in unintended ways.
