In my system, the power values of the battery come from the SmartShunt and can also be picked up from it. The topic I use for this is the following:

N / XXXXXXXXXXXX / battery / 288 / Dc / 0 / Power

Negative values are the consumption of power, positive values represent charging power.


It will be different for you because you use a Pylontech BMS, but there will also be a corresponding topic here.


I wrote a script that writes all the topics that are sent by Venus into a csv file. I can then evaluate these with Excel and search for the required topics.
