The `random` sensor platform is creating random sensor values (integers) out of a given range. This can be useful if you want to test automation rules. It generates a new value every time it is polled.

To enable the random sensor, add the following lines to your `configuration.yaml`:

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

Configuration variables:

- **name** (*Optional*): Name of the sensor to use in the frontend. Defaults to `Random Sensor`.
- **minimum** (*Optional*): Lower limit for the values. Defaults to `0`.
- **maximum** (*Optional*): Upper limit for the values. Defaults to `20`.
- **unit_of_measurement** (*Optional*): Defines the units of measurement of the sensor, if any.

See the [entity component options][entity-docs] to control how often the main component polls the random sensor. The default is 30 seconds.
