Grove TH02(connected via i2c) implementation not available in GrovePi repo

Hi,
GrovePi on master branch on github has a version that supports humidity & temperature sensor via digital port. Implementation @ https://github.com/Seeed-Studio/Grove_Temper_Humidity_TH02 on Github has an implementation for TH02 that could be used in Arduino IDE. I would like to use a version that doesn’t have Arduino dependency. Is this available?

Thanks,
Bindu
