The random sensor platform is creating random sensor values (integers) out of a given range. 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:
# Example configuration.yaml entry
sensor:
- platform: random
Configuration variables:
- name (Optional): Name of the sensor to use in the frontend. Defaults to
Random Sensor. - minimum (Optional): Lower limit for the values. Defaults to
0. - maximum (Optional): Upper limit for the values. Defaults to
20. - unit_of_measurement (Optional): Defines the units of measurement of the sensor, if any.
See the entity component options to control how often the main component polls the random sensor. The default is 30 seconds.
