Hi there....

Can we please get the changes you made to the source code so we can compile later versions.....? Do the changes support ethernet ?

Sorry that was NOT my question.  Can you please supply the changes you made to the userconfig file in the tasmota source code so I can compile my own software....

Thankyou

Hi Kincony

Thankyou....I wasnt sure if you had to do more.  I found the ethernet enabled in ESP32 and enabled the PCF8574 in tasmota....AS my board hasnt arrived so I cant test.

Appreciate your fast response :-)

yes, i think when you have a board, debug it will be better, just enable or disable comments on source code config.

Hi @admin

I have flashed attached firmware and performed configuration described above.
On the first start I have connected it to my Access Point(set my wifi/password to connect).

Now I would like to connect the board via ethernet, but can't configure it.
Do you have any recommendation on how I can set Eth configuration?

Thank you.

wifi and ethernet can't work at the same time, disable your wifi, just use ethernet.
