Change ssid hassio

Hi.
I have configured hassio with eth0.
What file do I have to modify to add to connect via wifi?
Do I have to connect via ssh?
Thank you

See the how-to.

Thanks!!!

Are you using HassOS? After you have created the my-network file and placed on a properly formatted and named USB drive, you can connect the USB drive to your raspberry Pi or other SBC and reboot, or go to Hass.io >> System tab of the UI and click on ‘Import from USB’. I think that works…

perfect. I will try it. Thank you
