# Home Assistant Community Add-on: UniFi Controller

This add-on runs Ubiquiti Networks' UniFi Controller software, which allows
you to manage your UniFi network via the web browser. The add-on provides a
single-click installation and run solution for Home Assistant, allowing users
to get their network up, running, and updated, easily.

This add-on supports all Home Assistant supported architectures, including the
Raspberry Pi.

## Installation

The installation of this add-on is pretty straightforward and not different in
comparison to installing any other Home Assistant add-on.

1. Search for the "UniFi Controller" add-on in the Supervisor add-on store
   and install it.
1. Start the "UniFi Controller" add-on.
1. Check the logs of the "UniFi Controller" to see if everything went well.
1. Click the "OPEN WEB UI" button, and follow the initial wizard.
1. After completing the wizard, log in with the credentials just created.
1. Go to the settings (gears icon in the bottom left) -> Controller (tab).
1. Change the `Controller Hostname/IP` to match the IP or hostname of
   the device running Home Assistant.
1. Check the box `Override inform host with controller hostname/IP`.
1. Hit the "Apply Changes" button to activate the settings.
1. Ready to go!

## Configuration

**Note**: _Remember to restart the add-on when the configuration is changed._

Example add-on configuration, with all available options:

```yaml
log_level: info
ssl: true
certfile: fullchain.pem
keyfile: privkey.pem
memory_max: 2048
memory_init: 512
```

**Note**: _This is just an example, don't copy and paste it! Create your own!_

### Option: `log_level`

The `log_level` option controls the level of log output by the addon and can
be changed to be more or less verbose, which might be useful when you are
dealing with an unknown issue. Possible values are:

- `trace`: Show every detail, like all called internal functions.
- `debug`: Shows detailed debug information.
- `info`: Normal (usually) interesting events.
- `warning`: Exceptional occurrences that are not errors.
- `error`:  Runtime errors that do not require immediate action.
- `fatal`: Something went terribly wrong. Add-on becomes unusable.

Please note that each level automatically includes log messages from a
more severe level, e.g., `debug` also shows `info` messages. By default,
the `log_level` is set to `info`, which is the recommended setting unless
you are troubleshooting.

### Option: `ssl`

Enables/Disables the use of a custom SSL (HTTPS) certificate with the in UniFi
web interface. Set it `true` to enable it, `false` otherwise.

**Note**: _When leaving this option disabled, UniFi will use a
custom/self-signed SSL certificate._

### Option: `certfile`

The certificate file to use for SSL.

**Note**: _The file MUST be stored in `/ssl/`, which is the default_

### Option: `keyfile`

The private key file to use for SSL.

**Note**: _The file MUST be stored in `/ssl/`, which is the default_

### Option: `memory_max`

This option allows you to change the amount of memory the UniFi Controller
is allowed to consume. By default, this is limited to 1 GB. You might want
to increase this, in order to reduce CPU load or reduce this, in order
to optimize your system for lower memory usage.

This option takes the number of Megabyte, for example, the default is 1024.

### Option: `memory_init`

This option allows you to change the amount of memory the UniFi Controller
will initially reserve/consume when starting. By default, this is limited to
512M.

This option takes the number of Megabyte, for example, the default is 512.

## Automated backups

The UniFi Controller ships with an automated backup feature. This feature works
but has been adjusted to put the created backups in a different location.

Backups are created in `/backup/unifi`. You can access this folder using
the normal Home Assistant methods (e.g., using Samba, Terminal, SSH).

## Migrating from an existing controller

If you want to migrate from an existing controller to the controller provided
by this addon, Ubiquiti has an excellent tutorial on this:

<https://help.ubnt.com/hc/en-us/articles/115002869188>

This article explains in detail how to use the UniFi Site Export Wizard
to quickly and easily export sites from one Controller
(including configuration and devices) to another (e.g., this add-on).

## Manually adopting a device

Alternatively to setting up a custom inform address (installation steps 7-9)
you can manually adopt a device by following these steps:

- SSH into the device using `ubnt` as username and `ubnt` as password
- `$ mca-cli`
- `$ set-inform http://<IP of Hassio>:<controller port (default:8080)>/inform`
  - for example `$ set-inform http://192.168.1.14:8080/inform`

## Known issues and limitations

- The AP seems stuck in "adopting" state: Please read the installation
  instructions carefully. You need to change some controller settings
  in order for this add-on to work properly. Using the Ubiquiti Discovery
  Tool, or SSH'ing into the AP and setting the INFORM after adopting
  will resolve this. (see: *Manually adopting a device*)
- This add-on does support ARM-based devices, nevertheless, they must
  at least be an ARMv7 device. (Raspberry Pi 1 and Zero is not supported).
- When using SSL, the following warning is shown in the add-on logs:
  `Warning: The JKS keystore uses a proprietary format.`. This warning can
  be safely ignored. There is nothing wrong and your add-on will function
  normally.
- The following error can show up in the log, but can be safely ignored:
  `INFO: I/O exception (java.net.ConnectException) caught when
  processing request: Connection refused (Connection refused)`.
  This is a known issue, however, the add-on functions normally.
- Due limitation, renewed SSL certificates are not picked up automatically.
  You'd have to restart the add-on in order for UniFi to pick up the change.
- Due to security policies in the UniFi Controller software, it is currently
  impossible to add the UniFI web interface to your Home Assistant frontend
  using a `panel_iframe`.
- The broadcast feature of the EDU type APs are currently not working with
  this add-on. Due to a limitation in Home Assistant, is it currently impossible
  to open the required "range" of ports needed for this feature to work.
- This add-on cannot support Ingress due to technical limitations of the
  UniFi software.
