The ``ina226`` sensor platform allows you to use your INA226 DC Current and Power Sensor
|
|
(`datasheet <http://www.ti.com/lit/ds/symlink/ina226.pdf>`__,
|
|
`eBay`_) sensors with
|
|
ESPHome. The :ref:`I²C Bus <i2c>` is
|
|
required to be set up in your configuration for this sensor to work.

Configuration variables:
|
|
------------------------
|
|
|
|
- **address** (*Optional*, int): Manually specify the i^2c address of the sensor. Defaults to ``0x40``.
|
|
- **shunt_resistance** (*Optional*, float): The value of the shunt resistor on the board for current calculation.
|
|
Defaults to ``0.1 ohm``.
|
|
- **max_current** (*Optional*, float): The maximum current you are expecting. ESPHome will use this to
|
|
configure the sensor optimally. Defaults to ``3.2A``.
|
|
- **current** (*Optional*): Use the current value of the sensor in amperes. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **power** (*Optional*): Use the power value of the sensor in watts. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **bus_voltage** (*Optional*): Use the bus voltage (voltage of the high side contact) value of the sensor in V.
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
- **shunt_voltage** (*Optional*): Use the shunt voltage (voltage across the shunt resistor) value of the sensor in V.
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
