SenseHAT temperature first reading is always half the second

[johngodley]

I don't know if this is a bug or just how the hardware works, but the first SenseHAT temperature reading is always about half the second. This is noticeable in the chart:

I think we add up the readings from the two sensors and average them - I wonder if maybe one of them has a 0 value and so we're getting half the actual reading?
