The ``ufire_ec`` sensor platform allows you to use your uFire Isolated EC sensor
2022-10-18 21:01:57 +02:00
with ESPHome. The :ref:`I²C Bus <i2c>` is required to be set up in your
configuration for this sensor to work. It requires also to have a temperature
sensor in the liquid tank; this can be on the same board or an external sensor
linked to the uFire EC configuration.

- platform: ufire_ec
id: ufire_ec_board
temperature:
id: temperature_liquit
name: Temperature

name: EC
Configuration variables:
------------------------
2023-01-24 18:56:46 +01:00
- **address** (*Optional*, int): Specify the I²C address of the sensor. Defaults to ``0x3C``.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
sensor. Defaults to ``60s``.
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
- **temperature_sensor** (*Optional*, :ref:`config-id`): Set the ID of the temperature
sensor. Only needed if the onboard temperature sensor is not used.
- **ec** (*Optional*, :ref:`Sensor <config-sensor>`): Set the EC sensor configuration. All options from :ref:`Sensor <config-sensor>`.
- **temperature** (*Optional*, :ref:`Sensor <config-sensor>`): Set the onboard temperature sensor configuration. All options from :ref:`Sensor <config-sensor>`.
- **temperature_compensation** (*Optional*, float): Set the temperature compensation for the EC
sensor. Defaults to ``21.0``.
- **temperature_coefficient** (*Optional*, float): Set the temperature coefficient for the EC
sensor. Defaults to ``0.019``.
.. _sensor-ufire_ec-calibrate_probe_action:
2023-01-24 18:56:46 +01:00
``ufire_ec.calibrate_probe`` Action
-----------------------------------
The EC probe have to be calibrated. For this you need know the EC reference value and temperature
of the calibration solution.
.. code-block:: yaml
# Example configuration entry
sensor:
- platform: ufire_ec
id: ufire_ec_board
# ...
# in some trigger
on_...:
- sensor.ufire_ec_board.calibrate_probe:
id: ufire_ec_board
solution: 0.146
temperature: !lambda "return id(temperature_liquit).state;"
Configuration options:
- **id** (**Required**, :ref:`config-id`): The ID of the ufire EC sensor.
- **solution** (**Required**, float): Solution reference EC value.
- **temperature** (**Required**, float): Solution current temperature.
.. _sensor-ufire_ec-reset_action:
2023-01-24 18:56:46 +01:00
``ufire_ec.reset`` Action
-------------------------
Reset the current calibration on the sensor.
.. code-block:: yaml
# Example configuration entry
sensor:
- platform: ufire_ec
id: ufire_ec_board
# ...
# in some trigger
on_...:
- sensor.ufire_ec_board.reset:
id: ufire_ec_board
Configuration options:
- **id** (**Required**, :ref:`config-id`): The ID of the ufire EC sensor.
