I cannot reproduce:

$ node
Welcome to Node.js v12.12.0.
Type ".help" for more information.
> let bytes = [0, 0, 0, 0, 0xfe, 0xc1]
undefined
> let decoded = {}
undefined
> decoded.temperature = ((0xffff << 16) + (bytes[4] << 8) + bytes[5]) / 100;
-3.19

Are you sure you are using the most up-to-date Decoder.js from the example you referenced?
