Getting started with Hass.io and Pi Zero W

Meestor_X · December 2, 2019, 12:08am

I realize the Zero is not the best device for running Hass.io, but it’s what I have currently.
I’ve also made this as hard as possible by not having a USB to Ethernet adapter so I can SSH into the Zero.

So…

I have a Zero W, Burned a micro-SD with Hass.IO on it, connected the zero to a monitor and keyboard, and booted it up,
It boots fine, but I cannot figure out how to configure the WiFi on the Zero to log into my local network. I’ve done lots of searching, but I must be missing something.
I can login into the host system on the Pi, using my keyboard and monitor, but what file do I edit to tell the OS what SSID and password to use so it will auto-logon to my WiFi network?

Thanks in advance for anyone’s help!

# Network

## Configure Network
HassOS uses NetworkManager to control the host network. In future releases, you will be able to set up the configuration using the API/UI. Currently only a manual configuration using NetworkManager connection files is supported. Without a configuration file, the device will use DHCP by default. These network connection files can be placed on a USB drive and imported to the host as described in [Configuration][configuration-usb].

## Configuration Examples

You can read the [Official Manual][keyfile] or find many configuration examples across the internet. The system is read-only, if you don't want the IP address to change on every boot, you should set the UUID property with a generic [UUID4][uuid]. Inside `\CONFIG\network\` on the USB or SD, create a file called `my-network` and add the appropriate contents below:

### Default

We have a preinstalled connection profile:

```ini
[connection]
id=my-network
uuid=f62bf7c2-e565-49ff-bbfc-a4cf791e6add
type=802-3-ethernet

[ipv4]

Where do I create the folder /CONFIG/network?
I tried going to the root folder but I get:
mkdir: can’t create directory ‘CONFIG’: Read-only file system

# Configuration

## Automatic

You can use an USB drive with HassOS to configure network options, SSH access to the host and to install updates.
Format a USB stick with FAT32/EXT4/NTFS and name it `CONFIG` (in all capitals). Alternative you can create a `CONFIG` folder inside boot partition. Use the following directory structure within the USB drive:

```text
network/
modules/
modprobe/
udev/
authorized_keys
timesyncd.conf
hassos-xy.raucb
```

- The `network` folder can contain any kind of NetworkManager connection files. For more information see [Network][network.md].
- The `modules` folder is for modules-load configuration files.
- The `modprobe` folder is for modules configuration files (/etc/modprobe.d)

I’d like to create the folder on my micro-SD card if possible.

Just not sure how to do that since the file system seems to be read-only?

To set up the network you have to put it on a USB stick as per directions in the second link. I’ve never seen it done it any other way (for Hass.io). If there is another way maybe someone else will see this and pipe up.

USB stick definitely easiest. You don’t need to keep it in the drive once it has booted up once and been set up.

Gotcha. Appreciate the help!

That did the trick. Luckily I had a USBOTG cable. Without that I’m not sure I would have been able to connect the USB key.

Thanks again!

Hi,
Are you able ti run hassio on pi-zero, if yes, can please shed light on the performance

cpu utilization,
is it laggy or any limitations…

Thanks in advance
