Generic ESP32

All ESP32-based devices are supported by esphomeyaml. Simply select ESP32 when the esphomeyaml wizard asks you for your platform and choose a board type from this link when the wizard asks you for the board type.

# Example configuration entry
esphomeyaml:
  name: livingroom
  platform: ESP32
  board: <BOARD_TYPE>

The ESP32 boards often use the internal GPIO pin numbering on the board, this means that you don’t have to worry about other kinds of pin numberings, yay!

Some notes about the pins on the ESP32:

  • GPIO0 is used to determine the boot mode on startup. It should therefore not be pulled LOW on startup to avoid booting into flash mode. You can, however, still use this as an output pin.
  • GPIO34-GPIO39 can not be used as outputs (even though GPIO stands for “general purpose input output”…)
  • GPIO32-GPIO39: These pins can be used with the Analog To Digital Sensor to measure voltages.
  • GPIO2: This pin is connected to the blue LED on the board as seen in above picture. It also supports the touch pad binary sensor like some other pins.
