# Example configuration.yaml entry
sensor:
  - platform: uptime
```

Configuration variables:

- **name** (*Optional*): Name of the sensor. Defaults to `Uptime`.
- **unit_of_measurement** (*Optional*): Units for uptime measurement in either `days`, `hours`, or `minutes`.  Defaults to `days`.

```yaml
# Example with configuration variables
sensor:
  - platform: uptime
    name: Time Online
    unit_of_measurement: hours
````
