ESP32-POE-ISO and DHT22

Maybe i am asking the wrong questions or just completely out of my element.

Looking for a tutorial on building a POE temperature sensor based off the olimex ESP32-POE-ISO board with a dht22 sensor. I have cat6 drops to every point i want to take data from so no need for wifi. But i am having an issue locating a tutorial on how to set it up. Are all ESP32 boards the same setup? Program used to write ESPHome? Like i said at the start, maybe i am out of my element or not binging the right question. Thanks

You can start with some basic tutorial or instructions for esphome via wifi. When you have all set up and working, step forward for POE.
