To enable Template Binary Sensors in your installation, add the following to

friendly_name (Optional): Name to use in the Frontend.
-
device_class (Optional): The type/class of the sensor to set the icon in the frontend.
-
value_template (Optional): Defines a template to extract a value from the payload.
-
entity_id (Optional): Add a list of entity IDs so the sensor only reacts to state changes of these entities. This will reduce the number of times the sensor will try to update it’s state.
-
on_delay (Optional): The amount of time the template state must be met before this sensor will switch to on.
-
off_delay (Optional): The amount of time the template state must be not met before this sensor will switch to off.

Considerations
+
If you are using the state of a platform that takes extra time to load, the
+Template Binary Sensor may get an unknown state during startup. This results
+in error messages in your log file until that platform has completed loading.
+If you use is_state() function in your template, you can avoid this situation.
+For example, you would replace
+{{states.switch.source.state=='on'}}
+with this equivalent that returns true/false and never gives an unknown
+result:
+{{is_state('switch.source','on')}}
Examples
In this section you find some real life examples of how to use this sensor.
-
Sensor threshold
-
This example indicates true if a sensor is above a given threshold. Assuming a sensor of furnace that provides a current reading for the fan motor, we can determine if the furnace is running by checking that it is over some threshold:

Some movement sensors and door/window sensors will appear as a switch. By using a template binary sensor, the switch can be displayed as a binary sensors. The original switch can then be hidden by customizing.

Switch as Sensor

+a Template Binary Sensor, the switch can be displayed as a binary sensors. The
+original switch can then be hidden by
+customizing.
This example combines multiple CO sensors into a single overall
status. When using templates with binary sensors, you need to return
-True or False explicitly. entity_id is used to limit which
+true or false explicitly. entity_id is used to limit which
sensors are being monitored to update the state, making computing this
sensor far more efficient.
This example creates a washing machine “load running” sensor by monitoring an energy meter connected to the washer. During the washer’s operation, the energy meter will fluctuate wildly, hitting zero frequently even before the load is finished. By utilizing off_delay, we can have this sensor only turn off if there has been no washer activity for 5 minutes.
