This is just to share a completed hardware+software project for monitoring my swimming pool water level and reporting to Home Assistant. The main pump got smoked last season, and some kind of warning system was needed. This project was not particularly complicated, but I always appreciate the examples in the community for new ideas and expanding my knowledge.
A deeper description is available at my blog with links to code and models. The core microcontroller code is my own C++ library used for all the ESP8266 devices I’ve deployed. For those of you looking to have full customization of your environment.
