When connecting the BMV712 to the SmartSolar 150/35 can I use a VE. Direct cable between the two or do I have to use Bluetooth? And, is the cable more reliable or is the Bluetooth so rock solid that you wouldn't think about using a cable?
I'm using the BMV712 battery temperature reading to cut off charging through the SmartSolar 150/35 in the condition of batteries below 40 deg F, and I want as robust a connection as possible.
