Hi,

Is there a way to update the wifi key on an already running home assistant on a pi zero w ?

Thanks !

It’s surely must be a test/dev system, just nuke it and start over.

If it’s running Raspbian, you can always place a new wifi configuration file into the /boot directory, and it will overwrite the wifi configurations at startup.

# 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]
