data_back= bus.read_i2c_block_data(address, 1)[0:4]
OSError: [Errno 5] Input/output error
any idea?

Hi @ferraris.simone,
Yes, that’s an issue with the GrovePi’s firmware that need to address. It’s on our backlog, so it’s scheduled to be fixed soon.
What may fix your issue on the moment is reverting the kernel version to an older version. You can do this by typing in the following command:
sudo rpi-update 52241088c1da59a359110d39c1875cda56496764 # kernel: downgrade to 4.4.50 - v7+
Thank you!
