Esphome Ethernet module (w5500)

Vish2024 · May 31, 2025, 5:30pm

Hey everyone,

So 2 months ago, I bought this waveshare 6 channel relay and was using it along with a w5500 ethernet module over ethernet and mqtt. I had this setup running for about a week (worked flawlessly) before turning it off. Fast forward 2 months - yesterday when I turned it on again, it wouldn’t show up online on my HA. I flashed the code again, restarted the thing, I even bought another waveshare 6 channel relay board+w5500 ethernet module - still nothing.

Here’s my esphome yaml:

Any idea why this might be happening? I don’t have access to my router’s admin page and so I have no clue if the device is actually connecting to my network.

Could it be updates related? My HA is updated to April 2025 (and so are all integrations, add-ons, etc.). Really seems bizarre. Thanks a lot for your help.

Hi

What are saying logs if you stay connected in USB to the ESP after flashing ?

Thanks for the reply Vincen. I’m uploading the code through web.esphome.io. I pressed the reset button a few times. Here are the logs:

Thanks for the log that confirms something I didn’t notice at first in your sketch ! It’s missing the network configuration itself:

manual_ip:
    static_ip: 10.0.0.42
    gateway: 10.0.0.1
    subnet: 255.255.255.0

and second if you use an external network module it’s known to fail quite a lot ! The Ethernet mode works only with boards that have Ethernet on it aside the ESP (I use it with some Kincony boxes and it works since years without problems).

Vish2024 · May 31, 2025, 6:59pm

I thought the manual_ip config. was optional? I did not have to set ip manually the last time. Anyways, the logs I shared was when I connected the board (with the ethernet module attached) to the my pc via usb without the ethernet cable attached. I’ll check logs again with the ethernet cable connected this time - I’ll posts results soon. Thanks a lot for your help.

Yeah ideally I’d love to use those esp boards with ethernet inbuilt. Costs are what’s keeping me from using them (those boards are expensive here).

swedude · May 31, 2025, 7:53pm

try a few different clock speeds

ethernet:
  type: W5500
  clk_pin: GPIO22 #GPIO18
  mosi_pin: GPIO02 #GPIO23
  miso_pin: GPIO23 #GPIO19
  cs_pin: GPIO21 #GPIO5
  interrupt_pin: GPIO03 #GPIO22
  reset_pin: GPIO19 #GPIO16
  clock_speed: 30Mhz ##<<<<<<<<<<

the defaults did not work for me on esp32c6

And short cables, or even better solder it to a PCB, i made a bt proxy with c6 and w5500 after i soldered it all together its super stable not a single fail in 60+days now

From logs I just posted above it looks like it’s able to connect to internet but not to my mqtt broker on HA

Yep your MQTT server uses TLS no ? It’s not supported so far on ESP32 with Arduino environment → MQTT Client Component — ESPHome
You need to either deactivate TLS on your MQTT server or tries to use the esp-idf instead of Arduino !
Why do you use MQTT instead of the native API to connect at HA ? It’s a lot easier and works like a charm
