I can't find the wifi conf file

Hi All,

I flashed a SD card with the hass.io image. I did that a few weeks ago. When I want to see the conf files to adjust my wifi (ssid & pass), I can’t find.
I only see the following files:
F:>dir /a
Unit Volume F is hassos-boot

Have you run the machine yet to carry out the actual installation?

Sorry… which installation do you mean? I flashed the SD card in a friends house, with his PC and the RP was working. Now, I am at home and I want just to change the wifi conf to connect to my wifi network.

Sorry, my mistake

You should create a file named wpa_supplicant.conf in the root partition of the card. Look around the web for examples from the Pi Zero W. Also, create a blank file named ‘ssh’ in the root directory, so you can login using SSH if there are any issues.

I don’t think that is a thing in hass.io.

Check here:

3. Optional - set up the WiFi or static IP. There are two possible places for that:

* On a blank USB stick with Fat32 partition (partition label: “CONFIG”), while in / directory, create  `network/my-network`  file

If you want to recongure the wifi, you should follow the same step.
Whenever HassIO find ans UB stick with partition label CONFIG (!important!) with on it a folder network and within tht a file my-network, it will releoad the setting in there.

What should be in there can be found here (see wifi section):
