The `synologydsm` sensor platform allows getting various statistics from your [Synology NAS](https://www.synology.com).

## Configuration

To use the `synologydsm` sensor in your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  - platform: synologydsm
    host: IP_ADDRESS_OF_SYNOLOGY_NAS

    password: YOUR_PASSWORD
    monitored_conditions:
      - cpu_total_load
      - memory_real_usage
      - network_up
```

<div class='note'>
After booting Home Assistant it can take up to 15 minutes for the sensors to show up. This is due to the fact that sensors are created after Home Assistant has fully been initialized.
</div>

<div class='note warning'>
This sensor will wake up your Synology NAS if it's in hibernation mode.
</div>

<div class='note warning'>

  If you set `ssl:` to `False`, you *have* to also explicitly set `port:` to **5000**.

## Separate User Configuration

Due to the nature of the Synology DSM API it is required to grant the user admin rights. This is related to the fact that utilization information is stored in the core module.

When creating the user it is possible to deny access to all locations and applications. By doing this the user will not be able to login to the web interface or view any of the files on the Synology NAS. It is still able to read the utilization and storage information using the API.
