I redid and actually all I needed to make it work was following the instructions of groove.py’s git page (https://github.com/Seeed-Studio/grove.py). Only had to make sure pip for python 2 was installed.
Oddly enough, I am still stuck with another issue. I have a Grove Base Hat for Raspberry Pi Zero and if I use it with a Pi Zero Wireless I have a return message stating Illegal Instruction. If I use the very same SD card on a Pi 3 B+ it works fine… Opening another thread for this, once it’s approved I’ll add a link.
