|
The `random` integration simply creates random values or state. This can be useful if you want to test automation rules or run an interactive demo. It generates a new state every time it is polled.
|
|
|
|
## Binary Sensor
|
|
|
|
The `random` binary sensor platform is creating random states (`true`, 1, `on` or `false`, 0, `off`).
|
|
|
|
### Configuration
|
|
|
|
To enable the random binary sensor, add the following lines to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
binary_sensor:
|
|
- platform: random
|
|
```
|
|
|
|
{% configuration %}
|
|
name:
|
|
description: Name to use in the frontend.
|
|
required: false
|
|
type: string
|
|
default: Random Binary Sensor
|
|
{% endconfiguration %}
|
|
|
|
## Sensor
|
|
|
|
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.
|
|
|
|
### 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:
|
|
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: integer
|
|
default: 20
|
|
unit_of_measurement:
|
|
description: Defines the units of measurement of the sensor, if any.
|
|
required: false
|
|
type: string
|
|
{% endconfiguration %}
