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:
The data in the serial monitor of Arduino IDE is Key Value pairs:

And my feeds:
No data in any of them.
What on earth am I missing, I have a feeling it is something small.
So now you need to SSH into the Pi and connect to the shield via miniterm (as I have said before).
The other problem is you are creating 2 interfaces - only one can be correct. BUT connect via miniterm to check the port is receiving the data.
[edit]
The other thing is that you have pubchannels and subchannels wrong.
It is like MQTT - an interfacer publishes data abd subscribes to receive data (internally within emonhub).
So the Serial interface is receiving data from the serial and wants to publish it to another interfacer to send it on (MQTT/HTTP)
In the serial interfacer then you want to publish the data to another channel so you need a pubchannels entry (note this is an array so there is a trailing comma).
If you are sending the data via MQTT, you have a corresponding subchannels entry.
swap your sub and pub around thus…
[[MQTT]]
[[[runtimesettings]]]
subchannels = ToEmonCMS,
pubchannels = ToRFM12,
(same in EmonCMS interfacer).
Still cant ssh. not sure why
Created the file, with no extension and connection refused.
Note my edit above.
Most likely you have the wrong IP address.
The only option is to connect a monitor (to check the IP address allocated) and then a keyboard to fix it.
Tx, Should I disable one, if so which one.
I am going to plug in a screen kyb. need to get this working lol
Sorry what edit?
It looks the same as my current config?
Lol, def dont have the wrong ip address.
I promise I am not a complete n00b, I am a coder in JS and full stack. Also have CCNA, CWNP etc etc etc.
Its just being a bit of a cow to me for some reason, so will connect it up the old fashioned way, lol.
No you have sub and pub channels inverted in the MQTT and emoncmsorg interfacers.
ah didnt spot that. thanks.
I am busy in the terminal now. will report back shortly
