EZO sensor circuits¶

The ezo sensor platform allows you to use your EZO sensor circuits with ESPHome. The I²C Bus 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, Time): The interval to check the sensor. Defaults to 60s.
id (Optional, ID): Set the ID of this sensor for use in lambdas.
All other options from Sensor.

lambda calls¶

From lambdas, you can set the temperature compensation for the sensors that support that option.

set_tempcomp_value(): Send the given temperature to the sensor.

// Within a lambda, set the temperature compensation value from the temperature sensor
id(ph_ezo).set_tempcomp_value(id(rtd_ezo).state);
