INA226 DC current and power sensor

The ina226 sensor platform allows you to use your INA226 DC Current and Power Sensor (datasheet, eBay) sensors with ESPHome. The I²C Bus 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 Sensor.

  • power (Optional): Use the power value of the sensor in watts. All options from Sensor.

  • bus_voltage (Optional): Use the bus voltage (voltage of the high side contact) value of the sensor in V. All options from Sensor.

  • shunt_voltage (Optional): Use the shunt voltage (voltage across the shunt resistor) value of the sensor in V. All options from Sensor.

  • update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.
