Feedback on my setup using an existing pi with emonTX connected directly via serial cable in the US with a PV system

@TrystanLea:

@montgomeryb is the second user in barely more than that many days who has been caught out by the mislabelled Tx and Rx lines on the emonTx - the first. I’ve lost count of the number of times I’ve explained it here, but the complaints continue to come in. It’s in the FAQ, it’s in many forum answers, but can the warning be put in more places where more people are likely to see it and heed it? For instance, there’s no mention that I can find in the Guide, the only mention I can find outside this forum is the Wiki.
