ESPHome provides built-in support for the BME680 sensor with a fully open-source implementation; however, it is not compatible with all the sensor’s features. The project also includes Bosch’s proprietary BSEC v1 and v2 software libraries that support different ESP boards. Learn how to set up and configure your sensors in this post with examples for the ESP32 S2 and C3 boards.

During my search for a small and cheap ESP32 board to use with ESPHome IoT projects, I stumbled upon the amazing ESP32-S2 Mini. This board is the compact and low budget option I was looking for, and while it is available on AliExpress from various sellers, there are a few details to consider.
