Error while installing gfFermentation

Hi Wardsimon,

Thanks for working on a tool for communicate with the Grainfather fermenter. Very much appreciated.

I get the following messages when installing on a RaspberryPi 4:

_Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple

Complete output from command python setup.py egg_info:

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-Ohk2A2/gffermentation/_

Any idea what's going wrong or what to do to overcome this issue?

Thanks in advance for your help,

Hubert.
