I have a Minut sensor in each of my 3 Airbnb’s. I got them for noise levels and to be a good neighbor by being alerted as soon as noise levels become unacceptable (which has yet to happen, I must be very lucky in guests). But when a washer hose broke in an unoccupied property, the Minut humidity level sensor alerted me. Family and friends were so impressed, they all have purchased one for their private homes. I use mine to get a sense of what my guests are up to without being intrusive or infringing on their privacy. My Minut sensors increase my peace of mind when guests are in my personal and investment properties. And they paid for themselves by alerting me to a potential whole property flood.
