Launch of the JK-BMS RS485 add-on for Home Assistant
#19
Good afternoon Jean-Luc,

First off let me start by thanking you for all the effort.

I do however have a few questions in trying to get this going:

I cannot get it to use TCP, although gateway is working through other tests. What do I need to change for the USB, as one cannot remove the data there.
EDIT: Managed to get the TCP operational, from yaml editor changed usb descriptor to IP and port, thank you

Then I found the following:
I have a 15cell battery, so JK app reports 15 and all the rest fine.
But through the Add-on, it uses 16cell and thus work out the average and delta from that, so average gives 15 cell data plus 0 and divide by 16, and delta take the value between 0V and eg 3.5, and report delta as 3.5.

Thanks again and kind regards
Riaan
