emonTX not finding feeds

Submitted by nrgsim on Sat, 25/04/2015 - 06:47

I purchased a pi base station and emonTX, but have not been able to get it to work. I got the api key entered and all that, but the feeds are not recognized. Attached is the log..

Not at all sure what to do next and really appreciate any advise anyone may have.

Thank you

Is your emonTx working - does the LED flash once every 10 s or so? (assuming you have an ac adapter).
Does the LED on your Pi - on the RFM12Pi 'piggyback'receiver - flash at the same time?
Did you use the read-write APIkey?

I'm not a emonHub/Pi expert, Paul's (pb66) usual advice is:
"Set loglevel = debug in /etc/emonhub/emonhub.conf and then run tail -f /var/log/emonhub/emonhub.log to display the log messages as they happen. All this is done by user pi, not root."
Then post the log so that he can take a look.

Thank you kindly for the help. Yes I do have an ac adapter the emonTx and its LED does flash once every 10 s or so.

The LED on the Pi turns on but- the RFM12Pi 'piggyback'receiver does not flash at the same time.

Yes I did use the read-write APIkey.

Ill setup the debug and post the log, thanks again

The emonhub.log should give you some info on what is happening, The fact that the emonTx is flashing and yet the RFM2Pi isn't suggests possibly either they are out of range ( or interference/obstacle etc), operating on different frequencies (ie 433 v 868) or the group ID's do not match.

Thanks,

I have not seen the RFM2Pi flash but the pi lights up.
I ordered both at 433
The two devices are a couple feet from each other so range interference/obstacle etc should not be an issue.
I was not able to find the emonhub.log

Attached are some pics of what I see- sorry if I am missing something and thanks for any help.

Sorry to hear your having trouble. The photos are too small for us to see the output. Pleaser try attaching larger res photos.

Yes, much more readable. I can even read your api key!

The problem would be easier to resolve if you posted your emonhub log;

$ tail -f /var/log/emonhub/emonhub.log

Dear Paul,

Yes I suppose I should have removed my api key..

Ill try the command you have provided.

Sorry for the newb questions, but could anyone please let me know the process I need to use to get this to work? For example where do I enter this and then how do I get the log file off of the pi?

That command will display the log in your ssh client, you can then highlight and copy it (Ctrl + c). Paste the results either directly in the forum, or if there's a lot of data - paste it in a Notepad txt file and attach it to your post.

PS I've hidden your screenshots for now.

Or if you are using the latest emonSD image you should be able to just use emonhub -dl ('-dl' short for display log)
