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.
