It seems that temperature is still important, I use this sensor in the winter and the temperature goes below zero and it’s bad when the sensor freezes over.
I tried to find the temperature relationship but I guess I’m doing something wrong 
maybe the hex values are in fahrenheit scale not celsius,because it is made in the USA
did linear regression analyze to hex values and there is something in 3 groups
some hex values are ~4600 most are ~37000 and some are ~~53000
when filter out values ~37000 it is linear
I also tested the battery voltages and found the battery value on the package
4 first blue numbers are temp and last 4 blue numbers are battery values

or
6 first blue numbers are temp and last 2 blue numbers are battery values
c500073fd54f0106240000000800903c02 65 d078b6ba
I noticed that if the temp is over 51 then the blue 5-6 number is 00
if the temp is over 25 then the 5-6 number is 01
if the temp is under 25 then the 5-6 number is 02
