It always struck me as strange that AirBnB never went in the direction of providing a simple base station with a CO/CO2 detector, noise sensor, Wifi AP (for IoT locks, lights, etc). I know the whole “hardware is hard” thing but you can surely find a vendor already selling something like this that’s most of the way there and can be white labeled.
I suppose on the flip side, rental gig economics is often predicated on the fact that corporate provides as little as legally or even ethically possible.
