Mysterious VE.Can Registers

I am getting a CANbus message "1CEFFF24 [8] 66 99 12 EE CF 74 00 00" for my BlueSolar MPPT 150 | 100 charge controller. I don't see a definition for VREG 0xEE12 in the VE.Can registers public pdf. Maybe the VREG is specific to the solar charger model?

If anybody knows what VREG 0xEE12 is that'd be great.

Also, I get VREGs 0x2030, 0x2004, and 0x2005. Which aren't defined in the VE.Can registers pdf, so any info on those would also help.

Thank you

Hi @akoelsch I've asked for you:

This vreg is the estimated battery temperature, it is sent on a 0.01K scale

Thank you Daniel! I appreciate it. Is there some pdf or file that has all of the VREG definitions other than VE.Can-registers-public.pdf? It's just that there are more and more VREGs being sent over my CANbus that aren't defined in that VE.Can-registers-public.pdf.

Here's my current list:

0x0202

0x0207

0x2004

0x2005

0x2030

0xEDB3

0xEDB4

0xEDB5

0xEE12

try looking in the VE direct Hex protocol, It looks like all the register addresses use the same space, which would make sense.
