JK BMS Integration

[sukhpal3y]

I Have successfully integrated my JK BMS with Home assistant (Running on Ras pi4) through ESP32. Here is the Yaml File for the Dashboard
Battery 48V100Ah Lithium 16S 3.2V Cells

Is it possible to colorize the Maximum and minimum voltage cells as shown in the JK BMS app?

An efficient and elegant way to apply color to the max/min voltage cells is by using css selectors with the help of the card-mod.
