A complete automation to control and manage the swimming pool.
The automation for a swimming-pool is something reserved to top-of-the-range systems. Here you can find an affordable, simple but powerful automation-system that you can build by yourself with a little time and effort.
Not only home things can be automated. Indeed, a swimming-pool is something where automation reports incomparable benefits in time, money and ecology.
The main objective is to build a modular system that allows controlling the peripherals as simple (and cheap) as possible, transferring all intelligence to a ESP32 controling all what happens in the pool (and outside).
Basically, you need a bypass PVC tube with the sensors, peristaltic pumps to inject liquids to regulate chemical parameters, and a box with a ESP32, that runs all the code of the project, responsible of all automation, monitoring and control.
As you can see the bill of material is not long. To increase reliability and maintainability, I chose standard components that can be assembled together instead of creating a PCB and solding individual components.

(TO DO)
This project has been develop using PlatformIO + VSCode.
If you begin with this environment, follow the excelent article: Getting Started with VS Code and PlatformIO IDE for ESP32 and ESP8266 (Windows, Mac OS X, Linux Ubuntu).
This article is proposed by the Random Nerd Tutorials site. This site is the Reference for everyone who develop with an ESP32. You'll find a lot of tutorials and examples.
Once your environment is ready, you can setup your project. (TODO)
To customize and configure the Pool Manager application, consult the dedicated README.
