Hass.io RPi 3 B Wifi Connection - ZinkNotTheMetal/HomeAssistant GitHub Wiki

This gave me a hard time at first which is why I will include some instructions.

If you want your Raspberry Pi on Wifi (not ethernet) here are the steps that I followed.

1. Download my wifi-template from my hassio_configs

2. Remove the wifi-template from the file name AND remove the file extension. So the file should just be 'system-connections' saved on your machine

3. Edit the file (using a text editor) and change the values to the wifi that you are connecting to. I used my 2.4GHZ network, but 5GHZ should work as well.

4. Generate a UUID here and place it in the UUID field

5. Get a USB flash drive and FORMAT using FAT32 the drive with the name CONFIG (all capitals)

6. Put your version of system-connections on the newly flashed USB flash drive

7. Unplug the ethernet port from your Raspberry Pi (Raspberry Pi will default to ethernet if it it's still plugged in)

8. Reboot your Raspberry Pi and it should now be on the network with proper credentials
