I want someone to open a direct (no hops between us) channel to me in lightning (she will be the funder, I'll be the fundee). How can I get the QR code of my node in my eclair wallet to show to the funder? I don't find the UI/setting for it.

Click the three dots in the top right corner, tap "Network Info".

Eclair channels screen with burger menu open

Your NodeId is visible on this screen

Eclair Network Info screen

Now, go to the URL ip.tyk.nu to find your IP address.

Now, in a Linux prompt (or WSL), install the PyPI qrcode package. On Ubuntu, it is available in the python3-qrcode package.

Now, execute this command (substitute the values you just learnt):

echo -n "<nodeID>@<IPaddress>:9735" | qr

The QR code is now visible in your terminal. If you want a real image, you can use zbarimg from the package zbar-tools.
