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?
So, you want the radio as well as a serial connection? You didn’t say that. I’m afraid I don’t think that’s possible, since there’s only one serial port available.
Why can’t the emonTx use the radio to send the data to the emonPi?
I was looking at a wired connection instead of radio as the units are next to each other , maybe a foot, it seems a bit daft yo use radio for that distance .
