Is chance to integrate different BMS's?

[sarzyk]

Hi. I have two batteries

One is oryginał deye RWM6.1 and the seccond is diy 280Ah lifepo4 16S with BMS from JK PB2A16S20P.
Separately dey of course works with my dey 12kW inverter (hybrid). The diy battery separately works too with the inverter.
But the problem is if I want to connect 2 batteries to my inverter.
I can't get communication between 2 batteries. Probably Deye BMS block communication with non deye battery.
Is there any solution for this?
I have Home Assistant maybe that is a chance to integrate 2 different battery with inverter.
Maybe exist some board where we can connect 2 different rs485 battery (to integration) and than wy connet the board via can with inverter?

Thank for reply.

You would have to develop a software "Master BMS" that communicates with each battery and collects the data from each battery and then compiles the individual battery data into "One Big Battery" data and then sends that data to the inverter using whatever protocol the inverter required. Basically a software protocol converter
