Battery 2 Temperature not reporting after update to 2025.01.9

[gt008]

Describe the bug

Following on from #1161 the battery 2 temperature on Solax Gen 5 X3 has stopped reading again after update to 2025.01.9. The Battery 2 Temperature started working on the 20th Jan and has worked correctly (ie reads the same as the temperature reported on the SolaxCloud) until I updated at 6am today, and after the restart the Battery 2 Temperature again reads 0.

I have considered reverting the Solax Modbus Version but I am nervous about this procedure as I have not done it before. I do have a full backup from a couple days ago that I think I can run but again nervous!

I am unclear what caused the Battery 2 Temperature to start working on the 20th Jan as I do not think I updated Solax Modbus that day?? I assumed that maybe there was a battery firmware upgrade that was run automatically? Was there a change to the regsiter or code related to Battery 2 Temperature in the latest release?

I have rebooted HA and reloaded Solax Modbus and looked in the logs but there is nothing obvious. SolaxCloud is still reporting the correct temperature for both batteries.

I would really like to get this issue sorted as I run a battery heating routine and adjust the charge/discharge profile accouding to battery temperatures as my batteries are in a cold environment, so any help much appreciated.
