INA219 DC Current Sensor
The ina219 sensor platform allows you to use your INA219 High Side DC Current Sensor
(datasheet,
Adafruit_) sensors with
ESPHome. The I²C Bus is
required to be set up in your configuration for this sensor to work.

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_voltage (Optional, float): The maximum bus voltage you are expecting. ESPHome will use this to configure the sensor optimally. Defaults to
32V(the max).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.
