The threshold binary sensor platform is consuming the state from another sensor. If the value is below (lower) or higher (upper) than the given threshold then state of this sensor change..

It's an alternative to the template binary sensor's value_template: to get the abnormal/too high/too low states.

{% raw %}{{ states.sensor.furnace.state > 2.5 }}{% endraw %}

To enable the threshold sensor, add the following lines to your configuration.yaml:

# Example configuration.yaml entry
sensor:
  - platform: threshold
    threshold: 15
    type: lower
    entity_id: sensor.random

Configuration variables:

• entity_id (Required): The entity to monitor. Only sensors are supported.
• threshold (Required): The value which is the threshold.
• type (Required): lower if the value needs to be below the threshold or upper if higher.
• name (Optional): Name of the sensor to use in the frontend. Defaults to Stats.
