Valve Component

:description: Instructions for setting up base valves in ESPHome.

|
||
|
|
||
|
The ``valve`` component is a generic representation of valves in ESPHome. A valve can (currently) either be *closed* or
|
||
|
*open* and supports three commands: *open*, *close* and *stop*.
|
||
|
|
||
|
.. note::
|
||
|
|
||
|
To use a valve in Home Assistant requires Home Assistant 2024.5 or later.

Base Valve Configuration
|
||
|
------------------------
|
||
|
|
||
|
All valve config schemas inherit from this schema - you can set these keys for valves.
|
||
|
|
||
|
.. code-block:: yaml
|
||
|
|
||
|
valve:
|
||
|
- platform: ...
|
||
|
device_class: water
|
||
|
|
||
|
Configuration variables:
|
||
|
|
||
|
- **name** (**Required**, string): The name for the valve.
|
||
|
|
||
|
.. note::
|
||
|
|
||
|
If you have a :ref:`friendly_name <esphome-configuration_variables>` set for your device and you want the valve
|
||
|
to use that name, you can set ``name: None``.
|
||
|
|
||
|
- **device_class** (*Optional*, string): The device class for the sensor. See
|
||
|
https://www.home-assistant.io/components/valve/ for a list of available options.
|
||
|
- **icon** (*Optional*, icon): Manually set the icon to use for the valve in the frontend.
|
||
|
|
||
|
Advanced options:
|
||
|
|
||
|
- **internal** (*Optional*, boolean): Mark this component as internal. Internal components will not be exposed to the
|
||
|
frontend (like Home Assistant). Only specifying an ``id`` without a ``name`` will implicitly set this to true.
|
||
|
- **disabled_by_default** (*Optional*, boolean): If true, this entity should not be added to any client's frontend,
|
||
|
(usually Home Assistant) without the user manually enabling it (via the Home Assistant UI). Defaults to ``false``.
|
||
|
- **entity_category** (*Optional*, string): The category of the entity. See
|
||
|
https://developers.home-assistant.io/docs/core/entity/#generic-properties for a list of available options. Set to ``""`` to remove the default entity category.
|
||
|
|
||
|
MQTT options:
|
||
|
|
||
|
- **position_state_topic** (*Optional*, string): The topic to publish valve position changes to.
|
||
|
- **position_command_topic** (*Optional*, string): The topic to receive valve position commands on.
|
||
|
- All other options from :ref:`MQTT Component <config-mqtt-component>`.

``valve.toggle`` Action
|
||
|
-----------------------
|
||
|
|
||
|
This :ref:`action <config-action>` toggles the valve with the given ID when executed, cycling through the states
|
||
|
close/stop/open/stop... This allows the valve to be controlled by a single push button.
|
||
|
|

Lambdas
|
||
|
-------
|
||
|
|
||
|
From :ref:`lambdas <config-lambda>`, you can access the current state of the valve (note that these fields are
|
||
|
read-only, if you want to act on the valve, use the ``make_call()`` method as shown above).
|
||
|
|
||
|
- ``position``: Retrieve the current position of the valve, as a value between ``0.0`` (closed) and ``1.0`` (open).
|
||
|
|
||
|
.. code-block:: cpp
|
||
|
|
||
|
if (id(my_valve).position == VALVE_OPEN) {
|
||
|
// Valve is open
|
||
|
} else if (id(my_valve).position == VALVE_CLOSED) {
|
||
|
// Valve is closed
|
||
|
} else {
|
||
|
// Valve is in-between open and closed
|
||
|
}
|
||
|
|
||
|
- ``current_operation``: The operation the valve is currently performing:
|
||
|
|
||
|
.. code-block:: cpp
|
||
|
|
||
|
if (id(my_valve).current_operation == ValveOperation::VALVE_OPERATION_IDLE) {
|
||
|
// Valve is idle
|
||
|
} else if (id(my_valve).current_operation == ValveOperation::VALVE_OPERATION_OPENING) {
|
||
|
// Valve is currently opening
|
||
|
} else if (id(my_valve).current_operation == ValveOperation::VALVE_OPERATION_CLOSING) {
|
||
|
// Valve is currently closing
|
||
|
}
|
||
|
|
||
|
.. _valve-on_open_trigger:
|
||
|
|
||
|
``valve.on_open`` Trigger
|
||
|
*************************
|
||
|
|
||
|
This trigger is activated each time the valve reaches a fully open state.
|
||
|
|
||
|
.. code-block:: yaml
|
||
|
|
||
|
valve:
|
||
|
- platform: template # or any other platform
|
||
|
# ...
|
||
|
on_open:
|
||
|
- logger.log: "Valve is Open!"
|
||
|
|
||
|
.. _valve-on_closed_trigger:
|
||
|
|
||
|
``valve.on_closed`` Trigger
|
||
|
***************************
|
||
|
|
||
|
This trigger is activated each time the valve reaches a fully closed state.
|
||
|
|
||
|
.. code-block:: yaml
|
||
|
|
||
|
valve:
|
||
|
- platform: template # or any other platform
|
||
|
# ...
|
||
|
on_closed:
|
||
|
- logger.log: "Valve is Closed!"
