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.

    # Example configuration entry
    sensor:
      - platform: ina226
        address: 0x40
        shunt_resistance: 0.1 ohm
        current:
          name: "INA226 Current"
        power:
          name: "INA226 Power"
        bus_voltage:
          name: "INA226 Bus Voltage"
        shunt_voltage:
          name: "INA226 Shunt Voltage"
        max_current: 3.2A
        update_interval: 60s

Configuration variables:
------------------------

- **address** (*Optional*, int): Manually specify the I²C 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``.
