Spike in IBTS reading on every roast

[solohorroman.PepS]

Hi, all!

I’ve recently received my long-awaited Bullet R2 and I’m super excited to dive deeper into the roasting world.

Upon arrival, I’ve done 7 seasoning roasts until the beans became oily and 2 actual roasts with a roast recipe from the Bullet manual.

One thing I’ve noticed is that during every roast, starting from the 1st one I get a weird flick in IBTS reading along with spike in I-ROR readings (screenshots attached).

Reading the posts of others I’ve never seen behavior like this on their graphs. First I would have assumed that the IBTS sensor is dirty but the issue started from the first roast I’ve done.

Has anyone encountered an issue like this and is this an issue at all?

Thanks in advance.

Hi @solohorroman.PepS

For your reference, this looks similar to the issue discussed here:

IBTS offset problem for newer roasters

About 3 weeks ago we saw some strange behavior in the IBTS sensor data for the R2 and R2 Pro models. More specifically, the temperature seemed to take a sharp upward turn after 165°C and then stay higher than it should have. Consequently, the FC temperature and end temperature were off by up to ~15°C, and since preheating is most likely above 165°C it also affects your preheating temperature. After weeks of investigation, internal testing, and supplier and distributor involvement, we have now h…

I suggest updating the firmware to v159, as it may help fix this issue. You can find the firmware files here:
