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.

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

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

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

Configuration variables:

- **entity_id** (*Required*): The entity to monitor. Only [sensors](/components/sensor/) 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`.
