I have Raspberry Pi with a Grove Pi and want to use more than one digital light sensor. Looking through the Grove_i2c_digital_light_sensor.py file, I don’t see where i2c port 1,2 or 3 is addressed. The sensor works on any of the i2c ports. If I populate more than one port with light sensors, the Lux value returned is 0 compared to higher values when using only one port. Is it possible to use more than on digital light sensor on a single Grove Pi. If so how do I do it?
