[Bug]: Temperature flat line around 180-185 deg F (~85C) on Inkbird IBT-6XS

[mrand]

What happened?

I'm loving this component - thank you so much!

When any of my temperature probes approach 185 deg F, that probe flat lines. I captured and example where it flat lines, then recovers when I take the temperature lower:

When it's in this state and I then connect the app, it displays the correct temperature.

Sensor type

Inkbird IBT-6XS

Relevant log output

Sensor 6 already well over 200 deg F, Sensor 4 around 167 deg F:

Sensor 4 back down to 176 deg F and displays properly.  Probe 6 somewhere in the 270-280 deg F range:

Thought I had upgraded to the latest, but just realized I hadn't. Problem looks to still exist on latest, although interesting behavior on rebooting HA while the temperature is that high: it appears to have captured a two readings in the high 180's before flat lining at 189.5 deg F.

[mrand]

After looking at it more, I'm thinking maybe this was resolved with the latest version and the flat line was a combination of no temperature change, and maybe a few missed captures or times outs. I'll close for now.

This bug was solved in one of the latest releases. Normal temperature sensors are limited to 85 degrees C (185 F) to filter out strange results. There is a special category of temperature (probe) sensors, that have a higher limit of 300 C. iBBQ-6 was recently added to that list, to fix the bug.
