As a dedicated Home Assistant user for years now, I came to write an ebook covering all the important topics around home automation and tinkering your own Esp32 based sensors and actuators.
Home Assistant is Open Source, written in Python and a lively community maintains over 3000 custom made components that allow you to control nearly everything in your home.
For everything else there is the cheap and handy Esp32 or ESP8266 microcontroller that comes with builtin wireless network support and the capability to control any hardware you can think of.
Soldering your own ESP8266 based sensors is really fun and allows you to add a lot of flexibility to your home automation. With a very low price tag of 5$ the ESP8266 microcontroller is a practical basis for all your custom made sensors and actuators.
