chunmi-ihcooker-v1joy_mibt1181 JCL02M model

[tuxcrafter]

I got an chunmi-ihcooker-v1joy_mibt1181 model JCL02M and on level 1 out of 99 it will still cook water to boiling temperature, the device is pretty useless as I wanted to control liquids from 25 to 40 degrees as well as keeping soups just boiling.

Is there a way to calibrate the machine? I have seen this option somewhere but don't know how to access the feature.

The Mi Home app also does not work fully for me when adding a new mode it gives a save failure (the app has all permissions enabled).
