BH1750 ambient light sensor~

This feature is included only in tasmota-sensors.bin

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 datasheet for more information.

Configuration~

Wiring~

BH1750	ESP8266
GND	GND
VCC	3.3V
SDA	GPIOx
SCL	GPIOy

Tasmota Settings~

In the Configuration -> Configure Module page assign:

GPIOx to I2C SDA (6)
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:

{"Time":"2019-11-03T20:45:37","BH1750":{"Illuminance":79}}

Commands~

Command	Parameters
Bh1750Resolution	resolution mode. x = sensor number (1..2) `0..2` = choose sensor resolution (`0` = high (default), `1` = high2, `2` = low)
Bh1750MTime	Measurement Time value. x = sensor number (1..2) `31..254` = set measurement time (default = `69`)
