Conversion error with LT-33222-L LoRa I/O Controller

hello,
I’m getting closer to your world. I configured my dragino with TTN and then with cayenne. It works, but I immediately noticed a first “problem”: I connected to the AVI1 input the same power cable of the dragino (12Volt DC).
the data I see on cayenne is: 125.44000244141 Volt
The error is one decimal place!
the correct value would be: 12.544000244141 Volt
Considering that on TTN as decoder payload I used “Cayenne LPP”, how can I correct errors of this type directly on CAYENNE?

are you getting the correct value on your TTN console?

PAYLOAD FROM TTN:
0000 0000 3102 0000 38

From the Dragino user manual on page 11 I find the information to infer the tension:

AVI1 is 0x3102/1000=12,546V

So I assume the TTN data is correct. Do not you think?

can you share the user manual link.

here it is:

I am also using the Dragino LT-33222-L. TTN shows the correct value on my voltage input 1 as 8.939V, but Cayenne desktop shows 89.39V.
I am using the Dragino LPS8 (LG08) gateway with version LG02_LG08-5.3.1576467023 firmware.

can you private message me your devEUI.
