Hi,
I purchased a Power Over Ethernet ESP32 (M5Unit-PoESP32) thinking I could run sensors and send the data over to either Home Assistant, Blynk or my own server. But receiving the unit I realize I have no idea how to use it even after reading all the online doc.
I purchased a USB Downloader Kit and I'm able to connect to it with my computer now and download the firmware.
-
In Arduino IDE what unit type should I select? The closest I found was "ESP32-WROOM-DA" but have never been able to see the serial output.
-
How do people use this device with the default firmware ??
-
Is there I2C pins I can use to plug sensors ?
-
In my Arduino IDE code I usually include WiFi.h. What is the replacement to have my same code work over ethernet?
#include <WiFi.h> // importing all the required libraries
#include <WiFiClient.h>
Thanks!
Frank
