Duty Time
=========
.. seo::
:description: Instructions for setting up a sensor that tracks the duty time of the some object.
:image: timer-play-outline.svg
The ``duty_time`` sensor allows you to track the total duty time of the some object, for example, a light bulb, in seconds.
Able to calculate the last turn-on time when an optional sensor ``last_time`` is included in the configuration.
Supports boolean signal sources: ``binary_sensor`` or ``lambda`` that returns a boolean state of tracked object.
As an alternative to controlling a component in automations, may be used the ``sensor.duty_time.start`` and ``sensor.duty_time.stop`` actions.
.. code-block:: yaml
# Example configuration entry
sensor:
- platform: duty_time
id: my_climate_work_time
name: My Climate Work Time
# Support logical sources (optional): 'binary_sensor'
sensor: my_binary_sensor
# ... EOR 'lambda'
lambda: "return id(my_climate).mode != CLIMATE_MODE_OFF;"
# Restore (optional, default: False)
restore: false
# Sensor for last turn-on time (optional)
last_time:
name: My Climate Last Turn-On Time
Configuration variables:
------------------------
- **sensor** (*Optional*, :ref:`config-id`): The ID of the ``binary_sensor`` to track the duty time. *May not be
used with* ``lambda``.
- **lambda** (*Optional*, :ref:`lambda <config-lambda>`): Lambda that will be called in a loop to get the current
state of the tracked object. *May not be used with* ``sensor``.
- **last_time** (*Optional*): Information of the last switch-on time sensor.
All options from :ref:`Sensor <config-sensor>`.
- **restore** (*Optional*, boolean): Whether to store the intermediate result on the device so that the value can be
restored upon power cycle or reboot.
Warning: this option can wear out your flash. Defaults to ``false``.
- **update_interval** (*Optional*, :ref:`config-time`): The update interval. Defaults to ``60s``.
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
- All other options from :ref:`Sensor <config-sensor>`.
Automations
-----------
In addition to all basic :ref:`sensor automations <sensor-automations>`, the component supports the automations below.
.. _sensor-duty_time-start_action:
``sensor.duty_time.start`` Action
*********************************
This action starts/resume time tracking. In lambdas, you may use the ``start()`` method.
.. code-block:: yaml
on_...:
then:
- sensor.duty_time.start: my_climate_work_time
.. _sensor-duty_time-stop_action:
``sensor.duty_time.stop`` Action
********************************
This action suspends time tracking. Causes the sensor to be updated, including the ``last_time`` sensor. In lambdas, you may use the ``stop()`` method.
.. code-block:: yaml
on_...:
then:
- sensor.duty_time.stop: my_climate_work_time
.. _sensor-duty_time-reset_action:
``sensor.duty_time.reset`` Action
*********************************
This action resets the duty time counter. Causes a sensor update. Does not affect the ``last_time`` sensor. In lambdas, you may use the ``reset()`` method.
.. code-block:: yaml
on_...:
then:
- sensor.duty_time.reset: my_climate_work_time
.. _sensor-duty_time-is_running_action:
.. _sensor-duty_time-is_not_running_action:
``sensor.duty_time.is_running`` / ``sensor.duty_time.is_not_running`` Condition
*******************************************************************************
This :ref:`Condition <config-condition>` checks if the ``duty_time`` counter is currently running (or suspended). In lambdas, you may use the ``is_running()`` method.
.. code-block:: yaml
# In some trigger:
on_...:
if:
condition:
# Same syntax for 'is_not_running'
sensor.duty_time.is_running: my_climate_work_time
