Hello,

I wanted to share an update.

My ioio system has been somewhat *in production* for 3 weeks.

I did apply a correction to the values read by tmp102 sensor yesterday.
I currently run with -3.5° celsius correction to get a credible value.

I expect the cause to be somehow hardware related (a slow creep, a variable
error)

Maybe the very variable humidity (between 30% and 70%, temp between 5°c and
20°c) is the cause of the readings I get.

I have now two more ioio boards to discover the origin of that gremlin. As
the ioiothingy is a temperature controlling magic wand, temp reading
accuracy is somehow... vital.

I will wire tmp102 & MCP9008, and maybe a couple of other sensors (combined
humidity & temperature) as a "lab".
And I'll hook a dht22 on an arduino too.
