ESPHome
With ESPHome you can build your own smart home devices without writing a single line of C++: you describe sensors and actuators in a short YAML file, ESPHome creates the firmware for the ESP32 and integrates the device locally into Home Assistant, with no cloud at all.
Here you will find everything ESPHome officially supports: ESP32 boards, sensors, relays, displays and LED strips. If you'd rather not solder, start with the Plug & Play Devices that come with ESPHome already installed.
