Multiple JK BMS (90kwh battery) and Cerbo

Hey guys does anyone know if the JK BMS is going to be added as a supported bms at some point ?

just sharing a battery we have built to off grid our house, its 96 cells of lithium 3.2v@302ah

We've arranged it in 3 packs of 30kwh. each pack has an individual BMS but I haven't figured out how to get them to talk to the Cerbo just yet

Anyway we have been recording out progress to date

i beleive this only works for a single bms not multiple, multiple nodes can run but only one of them impacts the charge and discharge. i need all three to work
