Integration Sensor

:description: Instructions for setting up sensors that integrate values over time.
|

|
|
|
|
The ``integration`` sensor is a helper sensor that can integrate values from other sensors over
|
|
time. This can for example be useful to integrate the values of a water flow sensor (in m^3/s) over
|
|
time (result is in m^3).
|
|
|
|
This component can be considered a more-generic version of the :doc:`total_daily_energy`.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
sensor:
|
|
- platform: integration
|
|
name: "Total Daily Energy"
|
|
sensor: my_flow_meter
|
|
time_unit: min
|
|
|
|
# The sensor to integrate, can be any power sensor
|
|
- platform: pulse_counter
|
|
# ...
|
|
id: my_flow_meter
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **sensor** (**Required**, :ref:`config-id`): The ID of the sensor to integrate over time.
|
|
- **name** (**Required**, string): The name of the integration sensor.
|
|
- **time_unit** (**Required**, string): The time unit to integrate with, one of
|
|
``ms``, ``s``, ``min``, ``h`` or ``d``.
|
|
- **integration_method** (*Optional*, string): The integration method to use. One of
|
|
``trapezoid``, ``left`` or ``right``. Defaults to ``trapezoid``.
|
|
- **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``.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **min_save_interval** (*Optional*, :ref:`config-time`): The minimum time span between saving updated values to storage. This is to keep wearout of memory low. Defaults to ``0s``.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
.. _sensor-integration-reset_action:
|
|
|
|
``sensor.integration.reset`` Action
|
|
-----------------------------------
|
|
|
|
This :ref:`Action <config-action>` allows you to reset the value of the integration sensor
|
|
to zero. For example this can be used to reset the integration sensor to zero at midnight with
|
|
a time-based automation.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_...:
|
|
- sensor.integration.reset: my_integration_sensor
