The threshold binary sensor platform observes the state of another sensor. If the value is below (lower) or higher (upper) than the given threshold then state of the threshold sensor is changed. It support also a range if lower and upper are given.
If the sensor is configured with no hysteresis and the sensor value is equal to the threshold, the sensor is turned off since it is not lower or upper with respect to the threshold.
It's an alternative to the template binary sensor's value_template: to get the abnormal/too high/too low states.

To enable the threshold sensor, add the following lines to your configuration.yaml:
# Example configuration.yaml entry
binary_sensor:
- platform: threshold
entity_id: sensor.random
lower: 20
{% configuration %} entity_id: description: "The entity to monitor. Only sensors are supported." required: true type: entity_id lower: description: The lower threshold which the observed value is compared against. required: false type: float upper: description: The upper threshold which the observed value is compared against. required: false type: float hysteresis: description: The distance the observed value must be from the threshold before the state is changed. required: false type: float default: 0.0 name: description: Name of the sensor to use in the frontend. required: false type: string default: Threshold {% endconfiguration %}
