I upgraded to 2.8p17 and it seems the issues with the hobby board
humidity/temp sensors have gone away. Unfortunately it seems my
TAI8570 sensor went beserk with it. I'm using parasitic power with it
over a long line so that's probably the issue. I'll be changing it to
a clean 5V source to see if that fixes it. Now if I could only find
some 6pin RJ11 plugs... :)
