The `nut` sensor platform allows you to monitor a UPS (battery backup) by using data from a [NUT](http://networkupstools.org/) (Network UPS Tools) server.

To use this sensor platform, you need to add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  - platform: nut
    resources:
      - ups.load
      - ups.realpower.nominal
      - input.voltage
      - battery.runtime
```

{% configuration %}
  name:
    description: Name prefix for defined sensors.
    required: false
    default: 'NUT UPS'
    type: string
  host:
    description: The host name or IP address of the device that is running NUT.
    required: false
    default: localhost
    type: string
  port:
    description: The port number.
    required: false
    default: 3493
    type: int
  alias:
    description: Name of the ups on the NUT server.
    required: false
    default: Will default to the first UPS name listed.
    type: string
  username:
    description: Username to login to the NUT server.
    required: false
    default: none
    type: string
  password:
    description: Password to login to the NUT server.
    required: false
    default: none
    type: string
  resources:
    description: Contains all entries to display.
    required: true
    type: list
{% endconfiguration %}

### {% linkable_title Example  %}

Given the following example output from NUT (your variables may differ):

```yaml
'ups.timer.reboot': '0'
'battery.voltage': '27.0'
'ups.firmware.aux': 'L3 -P '
'ups.mfr': 'American Power Conversion'
'battery.runtime.low': '120'
'ups.delay.shutdown': '20'
'ups.load': '19'
'ups.realpower.nominal': '600'
'battery.charge.warning': '50'
'battery.charge.low': '10'
'ups.vendorid': '051d'
'ups.timer.shutdown': '-1'
'ups.test.result': 'No test initiated'
'ups.firmware': '868.L3 -P.D'
'battery.mfr.date': '2015/05/08'
'ups.serial': '3B1519X19994  '
'ups.productid': '0002'
'battery.runtime': '2552'
'battery.date': '2001/09/25'
'battery.voltage.nominal': '24.0'
'battery.type': 'PbAc'
'ups.mfr.date': '2015/05/08'
'ups.status': 'OL'
'ups.model': 'Back-UPS RS1000G'
'ups.beeper.status': 'disabled'
'battery.charge': '100'
'input.sensitivity': 'medium'
'input.transfer.low': '88'
'input.transfer.high': '147'
'input.voltage': '121.0'
'input.voltage.nominal': '120'
'input.transfer.reason': 'input voltage out of range'
```

Use the values from the left hand column. Support is included for most values with 'ups', 'battery', and 'input' prefixes.

```yaml
sensor:
  - platform: nut
    name: UPS Name
    host: 192.168.11.5
    port: 3493
    alias: ups_name
    username: user
    password: pass
    resources:
      - ups.load
      - ups.realpower.nominal
      - input.voltage
      - battery.runtime
```

### {% linkable_title UPS Status - human-readable version %}

An additional virtual sensor type `ups.status.display` is available translating the UPS status value retrieved from `ups.status` into a human-readable version.

```yaml
sensor:
  - platform: nut
    resources:
      - ups.status.display
```
