In fact what caused my [BH1750] Device is not configured! was a cold solder joint on the module

It is a long time ago and I hope and trust you found the answer, but for those that may read this, many people apparently seem to have this issue and sadly there can be a hoist of causes and solutions. Proper solder joints is one of them. Some boards apparently have their silkscreen wrong and have SDA and SCL switched. Some claim that actually configuring the BH1750 (with the MODE commands
BH1750_CONTINUOUS_LOW_RES_MODE
BH1750_CONTINUOUS_HIGH_RES_MODE (default)
BH1750_CONTINUOUS_HIGH_RES_MODE_2

BH1750_ONE_TIME_LOW_RES_MODE
BH1750_ONE_TIME_HIGH_RES_MODE
BH1750_ONE_TIME_HIGH_RES_MODE_2
does the trick
or “adding a boolean”

Have a look here:

You van have your program do that. Either to say an SD card or if connected to wifi, via WiFi

I am having this same issue! did you fix it?

Just seeing in the serial monitor isn’t that useful.

Thanks

hi,
you probably have the SDA and SCL pins on digital 4 and 5. wire them on analog 4&5 and it should go well.

You may also need to check the sensor I2C address: https://raw.githubusercontent.com/RuiSantosdotme/Random-Nerd-Tutorials/master/Projects/LCD_I2C/I2C_Scanner.ino
