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. ## Configuration The preferred way to configure random helpers is via the user interface at **{% my helpers title="Settings > Devices & Services > Helpers" %}** and select the add button; next, select the {% my config_flow_start domain=page.ha_domain title=page.title %} option. To be able to add Helpers via the user interface, you should have `default_config:` in your `configuration.yaml`. It should already be there by default unless you removed it. If you removed `default_config:` from your configuration, you must add `random:` to your `configuration.yaml` first, then you can use the UI. ## Binary sensor The random binary sensor creates random states (`true`, 1, `on` or `false`, 0, `off`). ### YAML configuration To create 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 creates 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. ### YAML configuration To create 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 %}
