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`.
