The full story
The household kept forgetting the slow reverse osmosis tap and letting it overflow. The maker added an ESP32 linked to Home Assistant with a relay and water valve, so the valve only stays open for a set time.
The code was written with Claude. It works from a dashboard and physical buttons, and the maker says it works great.
