The ``ezo`` sensor platform allows you to use your EZO sensor circuits with
|
|
ESPHome. The :ref:`I²C Bus <i2c>` is
|
|
required to be set up in your configuration for this sensor to work.

# Example configuration entry
|
|
sensor:
|
|
|
|
- platform: ezo
|
|
id: ph_ezo
|
|
address: 99
|
|
unit_of_measurement: "pH"
|
|
update_interval: 10s
|
|
|
|
- platform: ezo
|
|
id: rtd_ezo
|
|
name: "RTD Temperature"
|
|
address: 102
|
|
accuracy_decimals: 2
|
|
unit_of_measurement: "°C"
|
|
update_interval: 10s
|
|
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **address** (**Required**, int): Specify the I²C address of the sensor.
|
|
- **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.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
lambda calls
|
|
------------
|
|
|
|
From :ref:`lambdas <config-lambda>`, you can set the temperature compensation for the
|
|
sensors that support that option.
|
|
|
|
- ``set_tempcomp_value()``: Send the given temperature to the sensor.
|
|
|
|
.. code-block:: cpp
|
|
|
|
// Within a lambda, set the temperature compensation value from the temperature sensor
|
|
id(ph_ezo).set_tempcomp_value(id(rtd_ezo).state);
