Adafruit TSL2591 on GrovePi

I am trying to run a TSL2591 LightSensor on the Grove PI via I2C. The adafruit library is installed but I have no success. Can somebody help?

Thank you!

Disclaimer: I am not DI, and do not know much about GrovePi.

I do not believe you need the adafruit lib. There is a program for that sensor on your GrovePi and on the DI GrovePi GitHub repository

Thank you very much for the quick response. I got the lib working but there is no meassurement. Only 0 Lux is displayed. The lib ist for the TSL2561 and I have a TSL2591. Do you have an Idea?
