The `random` sensor platform is creating random sensor values (integers) out of a given range. Returned values form a [discrete uniform distribution](https://en.wikipedia.org/wiki/Discrete_uniform_distribution), meaning that each integer value in the range configured is equally likely to be drawn. This can be useful if you want to test automation rules. It generates a new value every time it is polled.

## {% linkable_title Configuration %}

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

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

{% configuration %}
name:
  description: Name to use in the frontend.
  required: false
  type: string
  default: Random Sensor
minimum:
  description: Lower limit for the values.
  required: false
  type: string
  default: 0
maximum:
  description: Upper limit for the values.
  required: false
  type: int
  default: 20
unit_of_measurement:
  description: Defines the units of measurement of the sensor, if any.
  required: false
  type: string
{% endconfiguration %}

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