BH1750 - stodev-com-br/Tasmota GitHub Wiki

The BH1750 is a digital ambient light sensor module which uses I²C to communicate. The BH1750 provides you with a digital value in lux (Lx) over a range of 1 - 65535 lx. See Digital 16bit Serial Output Type Ambient Light Sensor IC for more information.

In the Configuration -> Configure Module page assign:

1. GPIOx to I2C SDA (6)
2. GPIOy to I2C SCL (5)

After a reboot the driver will detect BH1750 automatically and display Illuminance.

Sensor sends a tele/%topic%/SENSOR JSON reponse:
