I have not looked at my emonpi in a while as I mainly use it to monitor A/C energy use in the summer. Today I logged in and data has not been logging since December. All of my feeds say “inactive” and there doesn’t seem to be any obvious way to turn them back on.
I have updated the software and restarted the device but it’s still not working. I don’t really know how to start debugging this.
Welcome, Stephen, to the forum.
There isn’t a way to “turn on” your feeds - they will update when data arrives in emonCMS from emonHub and is processed. So you need to start where the data comes in and follow it through.
Have you looked at emonHub? This is where the data from the analogue part (the energy monitor) first enters the Raspberry Pi. If you go to Setup → Emonhub (the loudhailer icon), it should open showing the emonHub log. Every 10 s, it should update with new values, something like

If it is updating, look at the Inputs page and on the right there should be a column of times in green (up to 10 seconds since the data last came in) if that shows n/a in red, the data isn’t getting into emonCMS.
Still in Setup, go to Admin at the bottom of the menu, and look there: you should see a lot of Services listed, all should be Active and Running, except possibly for demandshaper: Not found or not installed
I’m not a RPi or emonCMS expert, so when you report back what you’ve found, I’ll need to hand over to somebody who knows more.
Thanks for your response. I have no clue how this thing works so it’s good to get some pointers!
The data is not appearing in emonhub. This is the log since it restarted about 11 hours ago:

This is telling me it can’t communicate with the “emon” board that does the energy monitoring. It looks as if the baud rate is wrong - 38400 is an old setting, we now use 115200 baud.
On the emonhub page, click on “Edit config” and very near the top, you’ll see this:

I don’t know the age of your emonPi - in the [interfacers] section, try changing the baud rate to 115200, save the file and watch for that error as emonHub restarts. If it reappears, both 9600 and 57600 have been used in the past, so try those in turn.
My Interfacers section looked like this:

The only baud rate setting is for EmonHubJeeInterfacer so I tried changing that but none of the values worked:

I bought and installed my emonpi around July 2022 if that helps? At least that is when the data started logging.
@TrystanLea @borpin Can either of you help here?
Hello @xylonsteve
Couple of things to try:
Full power cycle, turn off the power for at ~10s.
[Edit]
DON’T just pull the plug, Do a controlled shutdown of the RPi via the Shutdown button on the Admin page or the pushbutton and menu on the emonPi.
[ /Edit – RW]
You could try updating the emonPi firmware via the local emoncms admin > update page. E.g:
Do you have any radio nodes, e.g emonTx3/4 or emonTh2?
I did a hard restart. There are some other errors in my log:

Can I just re-install everything? How would I do that? I can get a fresh SD card and start again.
Is there any way to copy across my old data?

That’s not legal. Delete it so that the line reads
com_baud = 38400 # 9600 for old RFM12Pi # com_baud = 57600
A comment, ignored by emonHub, is anything following a ‘#’ character. If you want to keep a note in there to say what it was, adding orig com_baud = 38400 after the ‘#’ on the present line, or separately on a new line, is OK.
# orig: com_baud = 38400 is fine - it will be ignored.
Well that is embarrassing! I have copy+pasted this config so many times, I can’t believe that was it!
Thank you so much - it seems to be working now.
You need to look where you copied it from - before you do the same again 
Honestly it’s really embarrassing because I am actually a programmer and I write this kind of stuff all of the time!
I think what happened was I had that line commented out, and then I got confused and uncommented it and commented the next line instead. I updated that file loads of times trying different baud rates.
I think it shows how much I rely on syntax highlighting! I should really just set up my SSH key and log in and use vim.
I think it’s much more likely that to a fresh pair of eyes, it stood out like a sore thumb, whereas you’d seen it so many times it was familiar.
I know I can’t proof-read something I’ve written for at least 3 days, otherwise I read what I wanted to write and not what’s actually on the screen. Strangely, a different font helps in this case.
