On our boat, I currently have Multiplus, 7 Solar panels, each with MPPT and 6 lead acid batteries plus an old analogue battery gauge which I am thinking of replacing with a BMV712 Smart so I can get all the information about my batteries, loads, inputs from solar, shore power etc. The worry I have is that the gauge would be located maybe 7m away from our MPPTs in a different part of our boat. Right now, if I sit next to the location for the gauge, my iPhone cannot see the MPPTs on bluetooth. It's just too far away/hidden by the structure of the boat. Is the bluetooth "component" for the 712 located in the (included) shunt which I could install near the MPPTs, or is it in the gauge itself ? I'm worried that if its in the gauge, then I won't be able to access all the information about my system. Many thanks.
