Configuration variables:

address (Optional, integer): 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 .
adc_time (Optional, Time or both of the following nested options): The time in microseconds to perform a single ADC conversion. Defaults to 1100us . Valid values are 140us , 204us , 332us , 588us , 1100us , 2116us , 4156us , 8244us .
- voltage (Required, Time): ADC conversion time for Bus Voltage
- current (Required, Time): ADC conversion time for Shunt Voltage (Current measurement)
adc_averaging (Optional, integer): Selects ADC sample averaging count. Defaults to 4 . Valid values are 1 , 4 , 16 , 64 , 128 , 256 , 512 , 1024 .
update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s .

Sensors

The component offers four sensors. You can configure all or any subset of them. Each configured sensor is reported separately on each update_interval. The name option is required for each sensor configured. All other options from Sensor.

current (Optional): Calculated current output, Amperes.
power (Optional): Calculated power output, Watts.
bus_voltage (Optional): Bus voltage output (voltage of the high side contact), Volts.
shunt_voltage (Optional): Shunt voltage (voltage across the shunt resistor) value of the sensor, Volts.
