ESP32-POE-IND Rev.M

[PK]

Hi,

I am not experienced on ESP32. However, I intend to use Olimex ESP32-POE-IND Rev.M for measuring distance, with e.g. HC-SR04.

Is there anyone, that could walk me through the process of making this happen? I have for instance ESPHome, running on docker. It would be great to have this device adopted into home assistant

It should be doable.

There is a lot of info online about ESPHome and HC-SR04, for ESP32-POE-IND use the ESP32-POE config:

ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk:
    pin: GPIO17
    mode: CLK_OUT
  phy_addr: 0
  power_pin: GPIO12

Better check in the ESPHome forums for software help. They know their software better.
