Describe your issue:
…i have updated klipper to the latest version and i am now getting an error saying “Unknown temperature sensor ‘AHT20_F’”
it didnt do this before and i dont know why it has started. i have looked through my printer.cfg and i cant see any mention of AHT20 anywhere.
can anyone advise on what i should be looking for please?
You have a definition of that sensor in section [heater_generic heater_box1]
ahh, i dont have box1 in my printer.cfg. so does that mean that updating my klipper has erased my qidibox ?
As Klipper complains about it, it has to be somewhere.
Could it be that some definitions are outsourced into seperate config files?
Can you maybe upload your printer.cfg or at least check other available and included cfg-files for that mentioned section?
The klippy.log does not show where something is contained in.

okay, excellent i have found it… but now what? lol what does it mean? how can i fix it?
See here: Configuration reference - Klipper documentation
Maybe try changing the sensor_type to AHT2X.
However the klippy/extras/aht10.py says it is compatible with the AHT20 as well.
So as fallback AHT10 should work.
yay, that worked, i changed it to AHT10, now it just says “Unknown pin chip name ‘probe’”, so progress
Nice!
Ok, that might result from an outdated Cartographer3D section/definition, so probe is not yet available.
