Move with newest firmware has big temperature swings on the display
So after purchasing a Move and owning it for two months, I convinced Clive to send me a replacement (multiple broken components; long story). The new one has new firmware and a really strange issue—the temperature on the display swings quite wildly and won’t stay steady.
Perhaps it’s a result of the new firmware and the “Coffee Offset Correction” feature, which I don’t remember from my previous machine (though the offset might have been there)?
The machine arrived yesterday and I set it up this afternoon. After doing the initial setup flushes, I turned it back on to pull its first shot.
The warmup should take 15 minutes or so, so when I noticed that the temp was fluctuating so much after 5 minutes I wasn’t concerned. It was, however, different from how the other machine (with older firmware) functioned—that one would just slowly creep up to the set temp, not go above and below over and over again.
After about 30 minutes, it did seem that my set temp (204°) was now the baseline for the fluctuation. I figured that was good. However, it did still continue to fluctuate by as much as 4-5° above that set temp.
I noticed that this firmware has a feature called Coffee Offset Correction. Its default setting is 0°, which went to -4°F when I switched to Fahrenheit.
Given that the fluctuation was roughly 4°, is that the explanation for the fluctuation in the display? Or is this a known sign of something that might be wrong?
Here are two videos showing what’s happening—the first is after 5 minutes (so still warming up), the second is after 30 minutes:

What do we think? Normal with the new firmware, or is this second machine going back, too?
