What do you mean with “I pulled the ic off”? All you need for flashing is a simple USB-TTL cable.
All markings match my board, including the WT32-S1 mark on the ESP’s shielding.
I ended up buying a usb ttl and was able to flash it

I have one device running just this. It doesn’t really do anything. I have another which uses the Dallas 1-wire library to read temperature from a DS18B20 sensor.
Hi cubert.
I am planing to use the wt32-eth01 for windows and doors sensors. I adapted the binary sensor part of your code. i have some issues with my board it keep resetting.
Before i buy a new on, I just wonder if you use this code in your house and how reliable it is?
thanks for your help
One comment: I had trouble get it running with my USB programmer. Only after supplying real external 5V the WT32-ETH01 powered up correctly. (Programming went with USB-5V)
Hello,
I’m trying to install esphome in this esp32 but lan doesn’t seem to work. I notice my esp is esp32-eth01 v1.4. It’s different from wt32?
I put some images of connection too. the led seems to be always in red and doesn’t blink when i put some code.
my code:
esphome:

friendly_name: ethergloop

board: esp32dev
ethernet:

clk_mode: GPIO0_IN
phy_addr: 1
power_pin: GPIO16 # Power control for Ethernet PHY

# Enable logging for debug info

Hi Ricardo,
I seem to have bought the same type of boards.
I’m equally unable to get them to run, with identical errors as you have listed.
Tried multiple combinations of board & framework type & ethernet config, none seem to work.
cfr: When using wt32-eth01 as board and esp-idf as framework type, ethernet is not working on a WT32-ETH01 · Issue #5644 · esphome/issues · GitHub
cfr: esp32-eth01 lan problem · esphome/esphome · Discussion #4207 · GitHub
cfr: Ethernet Component — ESPHome
Also tried to delay boot, cfr
But that did nothing either.
I’m ordering new board from Aliexpress.
Now I’m going to make sure the text on the board reads WT32-ETH01 instead of ESP32-ETH01. Hopefully the text reflects a meaningful difference.
I have another similar board that I got working and I noticed that the wifi&BT module on the working board (i.e. the iron container with ESP32-WROOM-32 etched into it) also has a QR code etched in it.
The board that does not work does not have that.
Hopefully I can re-use the non working eth boards for wifi.
Let me know if you got cabled ethernet working after all. Thx.
br,
Ruben
