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` file:
```yaml
# Example configuration.yaml entry
sensor:
- platform: random
```
{% configuration %}
name:

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: integer
default: 20
unit_of_measurement:
description: Defines the units of measurement of the sensor, if any.
required: false
type: string
{% endconfiguration %}
