Serial Connection query. I have been running an Emonpi for the last 2 years on my solar system, which works just fine.
I now have a Moixa battery and wish to expand monitoring of the battery and use the battery app featured on another post. I have a temporary proof of concept TX3 running on a pi as a separate monitor system but would really like to connect the TX3 serially with the Emonpi system .
Is there a way to access the serial connection on the Emonpi ? To connect to the Emontx by a 3 wire cable?
