Imagine you are living in a townhome complex where expenses like water, landscaping and parking lots are managed by the Homeowners Association (HOA). All is well in the world until one day, the HOA instructs you to get rid of your hot tub because they have found that the meter you share with your neighbor is consuming significantly more water than any other townhome in the complex and they suspect because you have a hot tub, it must be your fault! If this sounds a little too specific to be a consequence (or a particularly nasty case of hot tub jealousy), that is because this nightmarish situation was exactly what my friend Sadie faced in 2017. Sadie fought the good fight and persevered to where she ultimately kept her hot tub after proving her neighbor had not one, but TWO leaking toilets that had been gradually getting worse and worse (for YEARS). Upon hearing of this -- as an unabashed data nerd -- I was of course thinking, "how could data from Sadie's meter have been used to detect and prevent this!?"
