Hi!
I have an installation where there are 2x 32s ant bms, and both connected in series a bit 64s). they are in constant charge at around 3.4v per cell (installed on an UPS - The ups mantain the voltage at around 216.7v at the end of the 64 cells).
The voltage from the start was quite well matched (around 108v per bms.), but now is diverging a bit. I have one bms at 106.9v, and the other one at 109.8v. The balancers are configured to mantain the cell matched. of both the bms.
I'm tempted to set an automation to force a balance with impossible parameters (for example 1mv per cell of max difference) on the bms with more voltage, so that i can try to match better the voltages of the 2 sets.
Is there a way to set some parameters of the BMS via the ESP?
