EMonTX Bad data after upgrade

The nunber are crazy most of time bad but some look good
the other 2 EMONTX are OK

15 is bad one was OK until the update.

Next time you post code or output, please remember to put 3 ‘backticks’ (normally found at the [top left of the keyboard] (typing - How do I type the tick and backtick characters on Windows? - Super User)) on a line of their own before the code, and 3 more backticks on a line of their own after the code.

```
code
```
If it is something like php you can add a language identifier that after the first 3 backticks so: ```php
Do this around each separate section - it makes it so much easier to read.

Now, what did you upgrade or update? Those numbers look to me as if you might have “whitening” on when it should be off, or vice versa. (Clue: 21845 = 0x5555, which is the number the value is XORed with to do the ‘whitening’.)

Why does data not match format?

Are you referring to emonCMS, emonHub? A few more words to explain wouldn’t come amiss. This forum isn’t a text messaging service.

Your title, mentions ‘upgrade’. Exactly what have you done?

Found there is an extra 15 at the end of config removed it and looks good again.
Why is my format different?
mine

       names = MSG, Vrms, Grid2, Solar2, Air2, Furnace

examples in config

       names = power1, power2, power3, power4, Vrms, temp1

mine msg, vrms, then sensors etc
examples sensor,sensor,sensor,sensor,vrms

Is format different if using serial?

Do you mean that you had two instances of the node definition for Node 15? If yes, that would without doubt cause a problem.

Yes. If you look at the source code for the sketch, you’ll see that the radio data packet is a “structure” made up of long and short, signed and unsigned integers that is transmitted as bytes. emonHub disentangles this according to the definition in emonhub.conf

If you’re sending serial data, it is sent as plain text in this format:
“MSG:1,Vrms:235.62,P1:682,P2:1066…” etc, only the variables in use are actually sent.

15 is back again with incorrect data and it not in the config.
I removed all unused and now is my config.

ERROR: Not in sync

Apart from the 3 emonTx’s, what other OEM equipment do you have? And are those standard emonTx’s? How are you conveying the serial data to your “base” station?

Because you are using the serial interfacer, you don’t need the radio. Is your “base” - whatever emonHub and emonCMS is running on - equipped with a radio that might be receiving the data in parallel with the serial connection? In other words, are you using an emonPi or emonBase to run emonHub?

You shouldn’t need to be reprogramming the emonTx’s. What are you trying to achieve with that? (What worries me is you might be creating more problems that you’re solving.)

Unfortunately, “not in sync” is a generic and not very helpful error message. It simply means avrdude did not get the expected response. What are you using as a programmer, and how have you connected that to the serial interface on the emonTx? Bear in mind that the Tx and Rx lines are swapped on the emonTx pcb, so as I’ve written so many times here, the emonTx is sending data on the pin labelled “Rx”, and it’s looking for data coming in on the pin labelled “Tx”. That’s contrary to convention.

The problem is flashing the emonpi all 3 emonTX updated OK

I have 3 Programmer - USB to serial UART one for each emonTX

avrdude done.  Thank you.

I’m not like this fellow, I can’t read your mind. All I know about your problem is in this thread, and getting information out of you is next to impossible. You’re not answering the questions, so I’ve got scant information to go on.

If anybody is going to be able to help you, you need to provide enough information. Take a look at the first few paragraphs of the FAQ. There’s a link at the top of this page.

I have one EmonPI and three EmonTX do not use Radio disabled as shipping time.
The EmonPi is connected to EmonTX var a Seral cables/USB to a Powered USB the SSD is also on USB hub. (/dev/ttyUSB0 - 2)
If I connect the Serial/USB direct pi does not have the power to boot.
The power supply is PI 4 3amp with emonpi cable.

I went into interface and Admin and updates


The EmonTX updated OK.
The EmonPI filed
Now get bad data on 15. looks like the update may of added node 15 that is not there anymore and still have the node 15 repeating good and bad data.
Is the problem the EmonPi is not updated of is there other problems.
This was a new Images I made yesterday and restored the backup. ( as old pi shipped would not update git problems.)
Does that help any?

My current config changes numbers and added 15 as junk until find out why?

I power off all emonTx and remove the serial cable and still get node 15
So from EmonPi or somehow from USB hub?

Please enable debug in the emonhub.conf. It will help you see what is being received from the emonTX NEW FRAME and what is happening with it.

You are getting live inputs, on Node 15 with all of the EmonTXs shut down? There must be another device in RFM range.

Again, enabling debug and tailing the log will help you.

Indeed, OR the r.f. has not been turned off on the emonTx that still believes it is Node 15 - if indeed one still does.

@NA7KR
When you wrote

which one, and what did you actually do? Which sketch did you use, and did you change and defaults, and did you change and configuration or calibration settings on-line afterwards?

Turning on whitening for Node 15 in emonhub.conf will give valid numbers. If those correlate consistently with the numbers that come in on one of the serial inputs, that will identify the problem. If different, that would suggest that it’s another transmitter on the same channel and within radio range. If that’s the case and you don’t intend to use the radio link that the emonPi provides by default, then you just remove Node 15 from emonhub.conf and it will ignore it.

Except I asked if that node was appearing with all the EmonTXs turned off.

Yes Node 15 is there with all emonTX off.
Remove node 15 form config does not help.

Does that help any?

If you are referring to this, it is node 5 (first number after the OK) - this is from the EmonPi.

This line must have a corresponding “NEW FRAME” line in the log.

In your configuration, you are publishing the same data twice to MQTT

Note it says Use with Nodes module which you are not using - just comment it out it is legacy.

These 2 MQTT publishes are the same data and that EmonTX must still be on and connected else you have a 4th one somewhere.

however, the publish with the topic emonhub will disappear into the ether.

Are they still connected by USB? Have you connected the power pins to the UART? That is powering them I suspect as all 3 are reporting data. Do not then power the EmonTX directly with DC as well.
