help needed - Smart shunt analysis

[schonstudent]

Hi Martin,
you might be able to help me with the analysis of the smart shunt data.
After decrypting the data I get the hex value
02e1100289a302f5ff17ffff6f0a0000000003000043698118eb

I struggel a lot with the outcome with the first information which is not 8 bit long like Aux Output value and further.
Maybe you have a hint how to interpret the battery current, consumed and SOC correctly (all with a field leng like 10,22,20 where I struggeln now.
I know the "aux output" hex value is empty because it's only 2 bit long.

Any hin?

Hi, I didn't touch this in years, and I don't have the device anymore, so I won't be able to help a lot, I'm afraid. What you should be able to find in the existing code is that a field named with a unit like, e.g. 'Ah' is not transmitted in 'Ah' but in something more fine granular, like 'mAh' - this is usually used to avoid fractional numbers and float encoding. So unexpectedly large values would hint that the value needs to be divided by a fixed factor like 1000. Probably you can make more sense by reading the manual to understand the actual meaning of a field and the expected maxima and minima. Then combine this knowledge with the state of your system. So read up what values SoC can have and check the original app what values is diplayed there for SoC Good Luck!
