Well Robert, still want you to be an ex and a spurt, I have installed Arduino IDE downloaded the all the files and put into the libraries, uploaded a sketch tried to verify and compile but nothing starts to load but comes up with errors and tops with emonlib.h file not found, one wire file not found. I have renamed all files to take out any hyphens. I’m sure it’s easier to qualify as a heart surgeon that to get to grips with this. LOL
Did you shut down the Arduino IDE completely (all windows/instances) and it still shows “not found”?
Are all the libraries in a ‘libraries’ subdirectory of your sketchbook, as per the ‘Learn’ docs? , and have you told the Arduino IDE where your “shetchbook” directory is? Do the names of the library files now match the names in each #include ... in the sketch?
Robert if you can read this attached picture, this is where I am at the moment. Realised the numbers are the line and place in the line where the error is but no idea what I need to edit too.
Only with difficulty - a copy&paste of the whole list of errors into your post would have been the best.
The first worry is, can you confirm which hardware you have, it is an emonTx V3.4 or an emonTx V3.2?
And which RFM module is it, a RFM12B or an RFM69CW?
The first you can get by looking at the p.c.b; for the second you need to compare it with the photos here: RFM12B & RFM69CW Wireless Transceiver Modules — OpenEnergyMonitor 0.0.1 documentation
The second worry is I couldn’t trace the sketch in Github (there’s no usable search for a filename) but fortunately, I found a private copy. So I know now what you’re looking at. The sketch is for an emonTx V3.2 using the RFµ328 processor module which in turn carries a RFM12B radio.
Is the screenshot the first error message? The error in line 385 suggests you probably don’t have the RFu_jeelib library, or you don’t have it in the right place.
You should also set the board to Arduino Uno in the Arduino IDE.
It is tx3.2.1 with rfu328 with rfm12b 433mhz, so just trying to get back to a starting point so I know it’s a clean install then I can use the esp8266 to talk my emoncms.
Have you checked the location of the libraries?

/home/r/OpenEnergy/Software is my “Sketchbook” directory.
I installed Arduino IDE which created a folder in “C” drive and I created a sketchbook folder within Arduino that contains a libraries folder with all the folders eg onewire, emonlib,rfu_jeelib.
When I load a sketch and verify and compile that’s when I’m getting the errors and it terminates. It sees emonlib because it tells me the path it’s using but doesn’t list them like your example, unless I’m using the wrong sketch.
I don’t know Windows that well these days, but my thoughts turn to a permissions problem.
I’ve got Win 10 running inside a virtual machine, my Arduino executable is actually on a shared drive (E:\arduino-1.8.13-windows\arduino-1.8.13\arduino.exe as seen by Windows, from Ubuntu it’s /home/r/VirtualBox VMs/Win10-Shared/arduino-1.8.13-windows/arduino-1.8.13/arduino.exe)

is output from the IDE (compiler/linker), not the sketch. It is produced when successful - I reproduced it to give you the paths to the libraries which worked for me.
If that folder is at the root of your C: drive, then I’d definitely be suspecting a permissions problem.
[Edit]
The Good (bad?) news is I’ve copied your sketch along with its directory (of course) into the ‘sketchbook’ in the VM and compiled it there with absolutely no changes.
N.B. The Arduino Shortcut “Start in” is set to the shared directory where the executable is. I have all permissions except Special
I am using Arduino 2.2.1 but I would imagine that doesn’t matter, but will try again later.
Thanks for your help and perseverance.
I have Arduino 2.2.1 - I used it to develop emonLibDB, and under Ubuntu it uses the same (not identical copies, the actual same) directories & files as the older version, so I don’t see why this in itself should be the issue. I’m still reasonably convinced your libraries aren’t where the IDE expects to find them.

Compilation error: 'ct1' was not declared in this scope
Robert please see my above post and i am stuck around the ct part, not sure if i am missing something or doing something wrong still. you were spot on about the libraries.
You’re definitely missing something - there’s a chunk missing out of line 278 and the ones following - and more worrying, it’s not line 278 in my version. Your source file is seriously damaged, I suggest dump it and try this one. It compiles for me:
emonTxV3_2_DiscreteSampling.ino (18.7 KB)
Line 111 in my file is missing in yours - this is what’s causing the “error: ‘ct1’ was not declared in this scope” etc errors.
Your Line 278 is my line 251 and it’s this: if (CT1) ct1.current(1, Ical1); // CT ADC channel 1, calibration. calibration (2000 turns / 22 Ohm burden resistor = 90.909) so I don’t know what you (or somebody) has done to lose the middle of the line. And it’s the same for all 4 c.t’s.
To Robert Wall
I have no idea how much time you devote to this site or helping people on it, Just a massive shout out to you and thanks, your sketch compiled and uploaded like a dream, so now I have a starting point I can start to work on it and hopefully move on to continuous sampling at some point.
Thanks once again

Quite a lot! Thank you for those kind words.
It might be worth trying to find out how or why your (failing) version got so screwed up, just so that a similar thing can be avoided in future.
Your starting point is the snippet of code way back in Post no.18
// ---------------------------------------------------------------------
// Key:Value format, used by EmonESP & emonhub EmonHubOEMInterfacer
// ---------------------------------------------------------------------
Serial.print(F("MSG:")); Serial.print(emontx.Msg);
Serial.print(F(",Vrms:")); Serial.print(emontx.Vrms*0.01);
if (CT1) { Serial.print(F(",P1:")); Serial.print(emontx.P1); }
if (CT2) { Serial.print(F(",P2:")); Serial.print(emontx.P2); }
etc, ending with
Serial.println();
along with the lines in loop( ) where the data is put together to transmit by radio.
In order to efficiently send the data by radio, it is packed into a struct called “emontx”, which is a collection of a handful of variables, so the first is emontx.Vrms in line 273. In this case, Vrms is a float, by multiplying by 100 and storing as an integer, we can send it with 2 decimal places but take up only 2 bytes. But you don’t need to do this with Wi-Fi and the ESP8266, so you can do
Serial.print(F(",Vrms:")); Serial.print(emontx.Vrms*0.01);
to send it as a human-readable KEY:value pair to the ESP8266, looking like
,Vrms:238.47
The comma separates it from the previous, be careful with the first pair that you send, and the final pair will need an end-of-line after.
You do similar with all the bits of data you want to send.
It might be a good idea to put all those lines together in a block (like the example) just above where the RFM sends the data:
send_rf_data();
Finally, you probably want to comment out this line because you don’t need it any more.
Also be careful with the debug statements - you won’t want those as well as the KEY:value data, also check the value of TIME_BETWEEN_READINGS is still appropriate, because the time to send the readings has changed.
I have searched through the sketch and can’t find where to turn the radio off. Line 96 is where I can see RFM12b settings but have no idea what I’m supposed to do. Sorry
This is what I get through serial connection but can’t enter config and don’t know if I can on this version.
No, there’s no on-line config on that sketch - it predates its introduction by a few years.
The radio message is sent in line 378. There’s no “switch” to turn it off (predates again), so comment out the line.
send_rf_data();
Robert Can you look at this sketch please and see where I have gone wrong, It compiles and uploads with no errors but not sure if i am still missing something. Emonesp still not connecting to tx3, I have 3 ct clamps connected but emoncms on inputs shows ct1 ct2 T0 freeram, srssi, psent, psuccess,
Thanks
emonTxV3 Discrete Sampling
If AC-AC adapter is detected assume emonTx is also powered from adapter (jumper shorted) and take Real Power Readings and disable sleep mode to keep load on power supply constant
If AC-AC addapter is not detected assume powering from battereis / USB 5V AC sample is not present so take Apparent Power Readings and enable sleep mode
