Phyn is an American smart water company, created in 2016 as a joint venture between Belkin International and Uponor, that makes whole-home water monitoring and shutoff devices. Its products read pressure and flow on the main line, learn the home's normal water use, detect leaks and plumbing problems, and can close the supply automatically. They connect over Wi-Fi with no hub and work with Alexa, Google Assistant and IFTTT, with water use reporting by fixture in the Phyn app.
