Images/screenshots/example configs of this device being used in action.
bl0940 sensor platform allows you to use BL0940 energy monitors sensors with
ESPHome. These are used in some Tuya-devices (e.g. the power metering BW-SHP10)
The communication with this integration is done over a UART bus.
You must therefore have a
uart: entry in your configuration with both the TX and RX pins set
to some pins on your board and the baud rate set to 4800 with 1 stop bit.

voltage (Optional): The voltage value of the sensor in Volts. All options from Sensor.
current (Optional): The current value of the sensor in Amperes. All options from Sensor.
power (Optional): The (active) power value of the sensor in Watts. All options from Sensor.
energy (Optional): Use the voltage value of the sensor in kWh. All options from Sensor.
internal_temperature (Optional): The internal temperature value of the sensor in °C. All options from Sensor.
external_temperature (Optional): The external value of the sensor in °C. Often not connected and gives garbage data. All options from Sensor.
update_interval (Optional, Time): The interval to check the sensor. Defaults to
uart_id (Optional, ID): Manually specify the ID of the UART Component if you want to use multiple UART buses.
