IndexError: list index out of range

I believe this is occurring when the python script grabs a line from the JeeLink that does not contain any data.

I need to look into filtering out JeeLink lines that don't contain sensor data. Maybe we can generate a .log file with everything, and then only attempt to upload JeeLink lines we know contain valid data.
