According to the help page (Hobbit menu -> Help -> Custom Graphs):

       note that Hobbit strips off any part of the name that is not a letter
or a number;

I don't know how it would handle your "+5 Volts", but it does strip spaces
from everything before the colon to get the label, so

   The CPU Temp: 45C

would result in an RRD variable called "TheCPUTemp".

There's an alternative way of doing this, which give you more control.  Take
a look at the hobbitd_rrd manual page (Hobbit Menu -> Help -> Manual Pages
-> hobbitd_rrd.  You can specify a script that processes the message to
generate the RRD definitions and the data values to store.  This allows you
much more flexibility when extracting the data from the message.
