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:

I looked at the services and they all appear to be on.

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:
[interfacers]
### This interfacer manages the RFM12Pi/RFM69Pi/emonPi module
[[EmonPi2]]
Type = EmonHubOEMInterfacer
[[[init_settings]]]
com_port = /dev/ttyAMA0
com_baud = 115200
[[[runtimesettings]]]
pubchannels = ToEmonCMS,
subchannels = ToRFM12,
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:
[interfacers]
### This interfacer manages the RFM12Pi/RFM69Pi/emonPi module
[[RFM2Pi]]
Type = EmonHubJeeInterfacer
[[[init_settings]]]

subchannels = ToRFM12,
group = 210
frequency = 433
baseid = 5 # emonPi / emonBase nodeID
calibration = 230V # (UK/EU: 230V, US: 110V)
quiet = true # Disable quite mode (default enabled) to enable RF packet debugging, show packets which fail crc
# interval = 300 # Interval to transmit time to emonGLCD (seconds)
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.
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:
