I love being able to monitor my system with the vrm portal, its a 48v lifepo4 system but I have a blue smart ip67 charger for my generator 12v starting battery. Is there a way to get that charger to talk to my my raspberry pi running venus os (or a cerbo gx for that matter) so that I can monitor the health of that starting battery remotely and even control the blue smart charger? If not what is the best way to get a voltage reading from that battery into my vrm portal?
