Is it possible to directly connect my emonTX (running latest 3 phase firmware v0.11 which has pulse counting & is ESP module compliant) to my emonPi using jumper leads? I envision using an AC AC psu for the emonTx and a separate psu for the RPi. If so how?

I got it from here … https://github.com/openenergymonitor/emontx-3phase

I, as the originator of the sketch, worked from my master copy. That has obviously been edited by someone else.

Robert - here’s where I’m currently at … Using the .ino file you sent but with SERIALOUT substituted in line 165 Just one CT connected plus AC adapter plus pulse sensor The RFM2Pi interfacer deleted from the emonhub config This interfacer used instead … [[SerialTx3e]] Type = EmonHubTx3eInterfa…

I thought I’d put those in. But as I’ve got sore eyes, a runny nose, a sore throat and a thick head, anything’s possible. You’re on your own for a few days.

Paul … I had no idea that I was using a different approach - having much more persistence than detailed knowledge. Just love yr … “good old fashion, tried and tested …”. My initial ref to ESP compliant was just because it was mentioned in the 3 phase sketch. (By way of background - I struggled w…

[image] johnbanks: If I’m not in a small minority I think actually you are - it’s rare that anyone asks about a serial connection. [image] johnbanks: should this approach be more fully documented in the technical part of the website? I think it is: emonTx3 User Guide — OpenEnergyMonit…
