Hass.io and Statlink (for IVT and Similar Heatpumps)

Hello all,

I am new to Home Assistant and it seems that the Hass.io interface is preventing me from running sudo and the like. I have the code and “H1” interface from Husdata for a Raspberry Pi 3 to monitor a heat pump but I am getting nowhere as the instructions expect command line access to Python. Should I just start again with a more basic installation of Home Assistant? Even root via SSH is restricted.
