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.
|
|
|
|
To enable the random sensor, add the following lines to your `configuration.yaml`:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
sensor:
|
|
- platform: random
|
|
```
|
|
|
|
{% configuration %}
|
|
name:
|

|

|
|
type: string
|
|
default: Random Sensor
|
|

|
|

|
|
default: 0
|
|
maximum:

|
description: Upper limit for the values.
|
|
required: false
|
|
type: int
|
|
default: 20
|
|
unit_of_measurement:

|
|
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.
