The Shield does not come with a sketch, because there is no processor, so you must have had one at some point.
Post No.7 has a link where you might have downloaded the sketch from. If you did, it’s on your machine somewhere - unless you deleted it. (Don’t do that, you can’t ever get it back from the Arduino.)
Thanks Robert.
Perhaps I leaving out some history where. I bought and set this up years and years ago. I has been sitting in a cupboard, only got it out when I started this thread. So can’t remember what is on the UNO. Will have to config a new sketch and start from scratch.
Ok got the sketch and added you recommendation, but cant get it to compile:

'emontx' was not declared in this scopeNope, I have tried multiple ino sketches. Can get serial output to the serial monitor with correct values. But nothing happening in emonCMS. Does pick anything up in the emonub log, or populate any inputs.
In the emonhub.conf it shows the TXshield, but it doesn’t show it on the inputs page.
Not sure what to try, any suggestions?
I’m afraid you haven’t changed the bit you added to keep it consistent with the rest of the sketch. You need to replace the whole of loop( ) with this:
void loop()
{
// Calculate all. No.of crossings, time-out
ct1.calcVI(20,2000);
ct2.calcVI(20,2000);
ct3.calcVI(20,2000);
ct4.calcVI(20,2000);

Serial.print(ct4.realPower);
Serial.print(" ");
Serial.print(ct1.Vrms);
Serial.println();
*/
//Serial.print(F("MSG:")); Serial.print(EnergyMonitor.Msg);
Serial.print(F("P1:")); Serial.print(ct1.realPower);
Serial.print(F(",P2:")); Serial.print(ct2.realPower);

Serial.println();
// Available properties: ct1.realPower, ct1.apparentPower, ct1.powerFactor, ct1.Irms and ct1.Vrms
delay(5000);
}
If you want the voltage, uncomment that line.
You won’t of course get anything through emonHub until the data format is correct, and as it hadn’t compiled, you weren’t sending it the correct format.
Then, in emonhub.conf, you will need to change whichever node it’s appearing as to this (assuming it’s Node 6):
[[6]]
nodename = emontxshield
[[[rx]]]
names = power1, power2, power3, power4
datacodes = h,h,h,h
scales = 1,1,1,1
units = W,W,W,W
If you do send the voltage, you’ll need this instead:
[[6]]
nodename = emontxshield
[[[rx]]]
names = power1, power2, power3, power4,Vrms
datacodes = h,h,h,h,h
scales = 1,1,1,1,0.01
units = W,W,W,W,V
And with a bit of luck (because I don’t have a Shield + Uno to test it on), that should work.
hi --if you get total frustrated you can always try this method – it not wired directly it connect the oemtx via wireles connection to what ever controller you want — Howto --emonTx - Shield ESPEASY and WEMOS R3 UNO
you need a wemos R3 uno/esp and and a oemtxshield
espeasy has a controller for oem to send to it via wireless connection or you can follow say this to a certain degree and send it directly to home assistant
The photo in post no.18 clearly shows there is NO radio fitted. Hence any method that required the radio will not apply.
the radio on the wemos R3 – one would assume since they have home automation software running it connected to router and has access to wireless network
Thanks Robert
Did what you said, can see the data in the serial monitor:
But still nothing coming through to emonCMS:
Doestn even show the emonTx Input at all.

First, for future reference, when posting code or bash output, please put in 3 ‘backticks’ (found at the top left of the keyboard normally) on a line on their own, then the code, then 3 more backticks on a line following the code.
```
code
```
If it is something like php you can add a language identifier that after the first 3 backticks so ```php
If you have thge serial data, you are getting close.
What we need now is the emonhub.log output from the start. Do a sudo systemctl restart emonhub.service and post the first 30 seconds of logs.
[edit]
How is this wired? I posted earlier…
On the Pi, open a miniterm session and see if you get serial data (edit for the right port and speed)
miniterm --rtscts /dev/ttyAMA0 115200
Thanks borpin.
Yeah I have the Tx to Tx.
I will do the back tick thing.
I cant run those commands as I can’t log into the pi via ssh. I took the card out and created /boot/ssh but still connection refused.
Any other way I can get you the log?
@borpin
Brian - you don’t need to swap wires if the output is getting into emonHub.
@dazzle_rsa
The output format you now have - you can see on the serial monitor - is in “key:value,” pairs. That’s the correct format for the EmonHubTx3eInterfacer, which is the one you have commented out.
Put that back in, and I think you should start seeing something.
Did you wait for it to fully boot?
Do it again and make sure (if creating the file in windows) it did not add an extension to the filename.
Add a monitor and keyboard.
That is still to be confirmed. The serial above is, I think, connected via the IDE. - COM18 is the clue I think.
Looking at the photos, the wires looked reversed.
I looked, but couldn’t tell from those.
When Darryl enables the correct interfacer, that’s one problem out of the way. At least we now know what’s actually coming out of his Shield.
I’ve spent quite a while ploughing through diagrams. Using the emonPi Shield drawing, and confirmed by the photo in the Wiki, I think the full serial connections are this:
| Shield | Signal | Raspberry Pi | ||
|---|---|---|---|---|
| Name | Pin | Pin | Name | |
| GND | 1 | GND | 6 | GND |
| 5 V | 3 | Power | 2 | 5 V |
| “Tx” | 4 | ←data | 8 | Tx |
| “Rx” | 5 | data→ | 10 | Rx |
| RST | 6 | Reset | 7 | GPIO 4 |
Note: The Shield V2.4 and emonTx V3.4 send on the “Rx” pin and receive on the “Tx” pin. The emonTx V3.2 is labelled correctly.
The pin numbers (counting GND = 1) will always be correct.
For one-way data, with no programming from the Pi, only GND, 5 V & Data → are required.
Wiring diagram
And my wiring…
I’d completely forgotten that. It’s now in my “fount of all knowledge” file. The picture is much better than the Wiki one. And as for the wiring diagram or schedule in the Wiki…
Hi Guys
Ok so this is where I am currently at after the suggestions:
This is the wiring I am using:
