Fix for UnboundLocalError: local variable 'io_ms2' referenced before assignment

[aweijnitz]

Hi, I tried to install your linux dashboard on my Raspberry Pi and ran into a minor issue (see below). Fixed it this morning and thought you might be interested in merging it back to your master.

Kind regards

Anders

HOW TO TRIGGER

Execute the script (following configuration according to the setup instructions)
