Template Sensor
|
|
|
|
|
===============
|
|
|
|
|
|
|
|
|
|
The ``template`` sensor platform allows you to create a sensor with templated values
|
|
|
|
|
using :ref:`lambdas <config-lambda>`.
|
|
|
|
|
|
|
|
|
|
.. code:: yaml
|

# Example configuration entry
|
|
|
|
|
sensor:
|
|
|
|
|
- platform: template
|
|
|
|
|
name: "Template Sensor"
|
|
|
|
|
lambda: >-
|
|
|
|
|
if (id(some_binary_sensor).value) {
|
|
|
|
|
return 42.0;
|
|
|
|
|
} else {
|
|
|
|
|
return 0.0;
|
|
|
|
|
}
|
|
|
|
|
update_interval: 15s
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Possible return values for the lambda:
|
|
|
|
|
|
|
|
|
|
- ``return <FLOATING_POINT_NUMBER>;`` the new value for the sensor.
|
|
|
|
|
- ``return NAN;`` if the state should be considered invalid to indicate an error (advanced).
|
|
|
|
|
- ``return {};`` if you don't want to publish a new state (advanced).
|

|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~

|
|
|
- **name** (**Required**, string): The name of the binary sensor.
|
|
|
|
|
- **lambda** (*Optional*, :ref:`lambda <config-lambda>`):
|
|
|
|
|
Lambda to be evaluated every update interval to get the new value of the sensor
|
|
|
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
|

|
|
|
- **id** (*Optional*,:ref:`config-id`): Manually specify the ID used for code generation.
|
