- YAYDrip – An open source water meter that detects leaks2023 · hackaday.io · ▲20
Hi HN, I'm developing an open-source water meter for Home Assistant and thought the HN community might be interested. I've been using some version of it after a few costly toilet leaks that my city meter missed. Recently, I decided to polish it up so others could use it.
