How I installed ESPHome on the wt32-eth01

shoeshineman · December 13, 2023, 7:59pm

Two remarks:

Use this at the beginning of your Yaml config:

esphome:
  name: 'XxXxXxX'
  platformio_options:
    upload_speed: 115200

esp32:
  board: 'wt32-eth01'

Second, after flashing the firmware using 3.3v, use 5v to power it up for operational use.

A “Copy & Paste” config to get started:

esphome:
  name: 'WT32ETH01'
  platformio_options:
    upload_speed: 115200

esp32:
  board: 'wt32-eth01'

Thank you! I had no clue on how to make connection. This helped me a lot!

johnsnow · December 20, 2023, 1:47am

how do you power these after flashing, the ones I see on aliexpress do not look to have usb port for power?

I assume use the 5v and ground pins?

andyboeh · December 20, 2023, 7:09am

Exactly. Or 3.3V and GND - check the manual.

johnsnow · December 20, 2023, 9:09pm

never gotten a manual before.

andyboeh · December 20, 2023, 9:23pm

Then I suggest you use your favorite search engine and type the words “wt32-eth01 manual”. You will be surprised how easy it is to locate the user manual.

Not sure if this will help anyone else, but I noticed that OTA’s can fail silently when you are using GPIO 12. Instead, the OTA update says it has succeeded, but on boot you will see the last compiled datetime has not changed. You will also notice that the upload takes less time (e.g. <1s vs ~3s). There will be no errors.

As per the docs, GPIO 12 is used during boot to determine the Flash voltage. That may be a red herring.

I have noted an issue about silent OTA failures with ESPHome, so please go comment if you are affected too:

Man… I still can’t get it to work.
I’m able to flash and when starting up the ESP32, there is activity on the LAN port.

No sign of the device on my router though.

The device is still powered through the USB to TTL by the %V and GND. Is this not correct?

Here’s my ESPHome config, just in case

esphome:
  name: ethergloop
  friendly_name: ethergloop    
  platformio_options:
    upload_speed: 115200

esp32:
  board: 'wt32-eth01'

# Enable logging
logger:
  level: 'DEBUG'

ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO0_IN
  phy_addr: 1
  power_pin: GPIO16  

web_server:
  port: 80

Can anyone think of anything I’m doing wrong?

Thanks

Depends on the current it can supply. Are you using 3.3V oder 5V? The 3.3V regulators on the TTL converters that I use do not provide enough power to run the board. Usually, I attach a USB breakout board to the 5V and GND pins and power it via a cell phone charger.

Guillaume_Corgnet · January 26, 2024, 6:14pm

Thanks for your reply. I’m using the 5V pin of the USB to TLL adapter to power it.
I have a micro USB to dupont adapter coming in the mail at some point.
I’ll try off a cellphone charger then.

Then I added a device, chose to skip the wifi step and edited the .yaml to this:

How do you skip the wifi step ? All I see is this

andyboeh · February 6, 2024, 3:51pm

The post refers to the ESPHome Dashboard, not to Home Assistant. You are trying to connect to an existing ESPHome node from Home Assistant, it doesn’t matter whether it’s WiFi or LAN in this screen.

~~You have to type IP address that router’s DHCP has given to the module. You can find it in the router’s menu, in the address reservation page.~~
My mistake. I should have read the message and the picture better.

pyto00 · March 19, 2024, 10:58am

Just to update you all.
There is a next generation of this WT32-ETH01 available which has a POE hat.
You can find it here

Bought a couple of wt32-eth01 on aliexpress and I keep getting this error:
A fatal error occurred: This chip is ESP32-C3 not ESP32. Wrong --chip argument?
Is it possible these are knockoffs? They are definitely not the new WT32-ETH01-EVO so I’m not really sure where to go from here… I can’t enable ethernet on the esp32-c3 stack because I get pin out of range errors on config validation… any ideas?

andyboeh · March 21, 2024, 4:02am

Which PCB markings are there? The eth01 has a version number printed. Or maybe you could post a picture of the board?

gaz99 · March 22, 2024, 2:28am

There is a ESP32-C3 based version called the ETH01-EVO that has a DM9051NP SPI ethernet chip. There is also a POE module for this board.

At this time there is no ESPHome support but there is a feature request so maybe add an I want this too.

benkrejci · March 23, 2024, 2:27am

Sorry, here’s a pic:

It looks identical to the ones I see online—hence thinking it’s not the EVO (and there’s no evidence of POE on this board)

One more piece of info is that I’m programming it using an old Arduino (I pulled the ic off). I don’t think that makes a difference, especially since it does flash c3 images just fine.
