:keywords: pump, peristaltic, atlas, ezo
|
|
|
|
The ``ezo_pmp`` component allows you to use an Atlas Scientific Peristaltic Pump with ESPHome.
|
|
Both the EZO-PMP (`datasheet <https://files.atlas-scientific.com/EZO_PMP_Datasheet.pdf>`__)
|
|
and EZO-PMP-L (`datasheet <https://files.atlas-scientific.com/EZO_PMP_L_Datasheet.pdf>`__) are supported.
|
|
The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this sensor to work.
|
|
|
|
.. note::
|
|
|
|
This component will not be directly controllable in the Home Assistant front-end automatically because
|
|
Home Assistant doesn't have support for pumps. In order to control the pump from the frontend you will need to use
|
|
templates to offer access to the actions you need. Please see :ref:`ezo-pmp-ha-config`.

ezo_pmp:
|
|
id: ezo_pmp
|
|
address: 103 # Default Address for the EZO-PMP.
|
|
update_interval: 60s
|
|
|
|
Configuration variables:
|
|
|
|
- **id** (**Required**, :ref:`config-id`): Specify the ID of the pump so that you can control it.
|
|
- **address** (*Optional*, int): Specify the I²C address of the sensor. Defaults to 103.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
|
|
sensor. Defaults to ``60s``.
|
|
|
|
Sensors
|
|
-----------------------------
|
|
|
|
Since the EZO-PMP offers a large number of sensors and each sensor needs to be polled individually, the code has been
|
|
optimized not to update a sensor that is not defined in the config. If you need very quick updates from the pump (under 3 seconds)
|
|
only enable the sensors that you actually need.
|
|
|
|
.. _ezo_pmp-current_volume_dosed_sensor:
|
|
|
|
``current_volume_dosed``
|
|
-----------------------------
|
|
|
|
This sensor indicates the volume (in milliliters) that has been dosed in the currently running or last ran dosing command.
|
|
|
|
.. code-block:: yaml
|
|
|
|
sensor:
|

|
|
|
|
Configuration variables:
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
.. _ezo_pmp-total_volume_dosed_sensor:
|
|
|
|
``total_volume_dosed``
|
|
-----------------------------
|
|
|
|
This sensor indicates total volume (in milliliters) that has been dosed since the last time the pump was turned on. Could be a
|
|
negative number if the pump has been run in reverse.
|
|
|
|
.. code-block:: yaml

|
|
|
|
``absolute_total_volume_dosed``
|
|
-------------------------------
|
|
|
|
This sensor indicates the absolute total volume (in milliliters) that has been dosed since the last time the pump was turned on.
|
|
|
|

|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
.. _ezo_pmp-last_volume_requested_sensor:
|
|
|
|
``last_volume_requested``
|
|
-----------------------------
|
|
|
|
Indicates the total volume (in milliliters) that is being dosed (or was if the pump has already finished) by a dose Action. When
|
|
using dosing actions that have a duration, the sensor will have the right calculation for total volume.
|
|
|

|
.. _ezo_pmp-max_flow_rate_sensor:
|
|
|
|
``max_flow_rate``
|
|
-----------------------------
|
|
|
|
The pump provides its own calculation of the maximum flow rate it can provide (in ml/minute). Dosing requests that exceed this rate
|
|
will fail. When using the :ref:`Dose Continuously <ezo_pmp-dose_continuously_action>` Action, this is the volume the pump will
|
|
dose every minute. This value will get updated after the pump is calibrated (see :ref:`ezo_pmp-set_calibration_volume_action`).

the calibration status by using the :ref:`Calibration Status<ezo_pmp-calibration_status_text_sensor>` sensor. For the procedure on calibrating the pump

Home Assistant Configuration
|
|
----------------------------
|
|
|
|
In order to provide control of the pump from the home assistant frontend it is important to expose the actions
|
|
as components that have UI rendering. This could be done using templates in ESPHome. Here is an example using a
|
|
`Template Button` and `Template Number` to dose a certain volume over time.

From :ref:`lambdas <config-lambda>`, you can also access the actions on the peristaltic pump to do some
|
|
advanced stuff (see the full API Reference for more info). The name of the functions is the same as the name
|
|
of the actions in YAML config.
