KC868-A2 configure yaml for ESPhome

[juan11perez]

Good day, I have one of these units set up with esphome. I'm using the recommended yaml for ethernet connection.

My intention was to use the board to restart my router when the internet fails. So the board powers the router and at the same time is connected to the router via the ethernet port.

The problem I have is that when I power cycle the board or associated relay powering the router, the esp32 chip does not reconnect to the network.

I can see the board connected to the network with it's associated IP address, but the esp32 does not seem to connect and therefore the board is inaccessible. I cant see it in homeassitant or on the assigned ip address webui.

If I just use it to power something else and it doesn't loose Ethernet connection, then it works fine.

However, as I explained the use case was as an internet 'watchdog'.

Is there an additional setting I must add to the esphome yaml?

See below my esphome yaml for reference
