Support for Esp32 Ethernet Boards?

[andreasm123]

This project works for me as well seamlessly - great work!

However i would prefer a non wifi version - are there any plans to adopt this great project to other Esp32 boards such as e.g. Waveshare ESP32-P4 POE ETH or ESP32-S3-POE-ETH?

Hello, it wouldn't be a problem, but I don't have an esp ethernet board right now. I'll put it in my notes. Thanks.

I would be interested in this aswell.
The birdfeeder is out of the wifi reception, but I can provide PoE to the location.
I can cover the charges for the hardware if you want to add support.

I (or Claude AI) managed to get this working on a Olimex ESP32-POE-ISO with ICS-43434.
BIrdNET-Go receives an RTSP-stream and the WebUI works just fine.

Are anyone interessted in the code, just ask.

[andreasm123]

I would be interested. Also which one of the boards on https://www.olimex.com/Products/IoT/ESP32/ESP32-POE-ISO/open-source-hardware did you use?

[mjorud]

I use Olimex ESP32-POE-ISO-IND. I went for IND because I use it up in the mountains with temperatures below -30 C.

[andreasm123]

thanks - is your Code (incl. wiring for the ICS-43434) somehwere available?

[mjorud]

I'm not a programmer and I have only used Claude AI to make it work.

The Arduiono IDE project attached:
esp32_rtsp_mic_birdnetgo.zip

[mjorud]

I forgot to mention the wiring.

ICS-43434 - Olimex
SEL - GND
LRCL - GPIO4
DOUT - GPIO32
BCLK - GPIO33
GND - GND
3V - 3V3

@mjorud
did compile your sketch today using the ESP32-POE-ISO and the Adafruit ICS-43434. Also ordered the BOX-ESP32-POE-ISO case to mount it outside. Works all like a charm. Thanks for sharing !

@Sukecz
Maybe worth to include in the docu as an option.

[mjorud]

I'm glad it worked for you.

@andreasm123 How does your audio "look like"?

I have this constant noise, both indoors and outdoors.

@mjorud

did capture a bird detection today (see image) - i've zero floornoise. My mic is connected via a small piggyback 'dev pcb' on top of the Olimex. The case is derived from the original Olimex STL which i adapted to my needs (closed some holes, added ventiltation holes and standoffs for better airflow as the Olimex POE parts get pretty hot). I'm powering my device via a Unifi USW Lite 16 PoE switch. In case pictures are wanted pls. let me know.

No noisefloor is impresive! Do you think the typical noisefloor is related to the WiFi on the standard ESP32s?

@andreasm123

I have updated the code for Olimex ESP32-POE. You can find it here: #42

[andreasm123]

Thanks for that. In case i'll find some time i'll give it a try. For now your first version works pretty well for me.
