Hi. I'm hoping for some wisdom from the crowd here. I've searched for an answer and come up blank. I have 2 controllers. A Bluesolar 100/30 MPPT controller and a Smartsolar 100/50 MPPT controller. I would like both units to be able to communicate to optimize charging and to be able to monitor and configure charging on both units via the bluetooth connection to my phone, Can I connect the 2 units with the VE.direct cable? Or do I need to connect the Bluetooth dongle to the Bluesolar unit?
