EmonPi failed update & feeds not showing

Emoncms Installation
,
1

Hi All,

I’ve had an emonpi running quite happily for about 6 months now on a solar home setup (one emonpi and 2 x CTs).

It was a pretty straightforward setup and left it to run quite nicely (is actually at my parents house so mainly manager / moinitor remotely).

But about a week ago it just stopped getting current readings. There may have been a power cut around that time. I’ve visited and tried to get it working again but with no luck. Originally the EmonHub light was red (under setup > Admin). All of those lights are now green.

Here are the latest logs (update and emonhub).

The one bit I couldn’t figure out is how to actually run “apt --fix-broken install’”. Tried it in the terminal shell after I had done the other bit it asked for (sudo dpkg --configure -a) but didn’t seem to like it.

Any advice gratefully received.
I do have a new SD card from Amazon coming and will be installing pi update onto that and then copying across, may or may not solve it but welcome any help here first.
It does seem that it gets stuck on the emonhub on RFM2Pi interfacer not sure how to correct this. I did a fresh copy of the emonHub config file and that didn’t help.

Thanks
Henry

That command is not relevant to emoncms as it was not installed via apt. I know it is in the log.

Did you do a full update or just emonhub? That could be the issue. click on full update (and be patient it sometimes takes a while).

image

I suspect it simply is not getting any data which is why it has stopped. Note this is the emonhub log not the emoncms log.

Did you run the update when you visited today?

What we really need is the output from the admin page which I realise in not local to you.

When you visit, can you click on the button Copy as Markdown next to Server Information on the Admin page and paste into a reply here please (no further formatting required).

If all the services are green, Then the next thing is the log file. Under the Disk section look and see if /var/log is over 50% full.

I’m around most days now so if you put up a message when you are going to visit then I’ll try and help. Late afternoons are best for me.

@borpin Thanks. I’m visiting for a few days so here is some stuff.

I did try a full update today. I’ve done both full update and emonhub update. Initially didn’t have much luck, but then went into terminal shell and ran “sudo dpkg --configure -a” which helped and it went a few more steps along (and got all the service lights green).

Disk - var log is on 3%

That really should not be required :frowning:

Could you do this please

sudo systemctl status {emonhub.service,feedwriter.service,emoncms_mqtt.service,service_runner.service}

When posting code or bash output, please put in 3 ‘backticks’ (found at the top left of the keyboard normally) on a line on their own, then the code, then 3 more backticks on a line following the code.

    ```
    code
    ```

If it is something like php you can add a language identifier that after the first 3 backticks so ```php

I was slightly surprised that it had got that bad myself, but that is what it said in the update log this morning, I had guessed that the SD card had gone bad, possible power cut or something.

I think that this is the script you asked for. It seems to repeat mutliple times but those 3 paragraphs are the same each time.

Unit service_runner.service could not be found.

Can you try and power down the emonPi. remove power completely (and the AC/AC if you have it.

Connect AC/AC and then the 5v power.

Just did a full power cycle as suggested but didn’t seem to change anything.

So the problem is this line (@TrystanLea note)

ERROR    MainThread Unable to create 'RFM2Pi' interfacer: module 'serial' has no attribute 'SerialException'

I’m not too sure how to debug it. @bwduncan any ideas?

[edit]

Can you try this please

sudo apt-get install -y python3-serial
sudo systemctl restart emonhub.service

and check the emonhub log.

Tried those two commands and unfortunately the log looks much the same.

New SD card arriving today so planning on downloading new package onto that and installing that this afternoon/evening.

Here is a copy from terminal shell

pi@emonpi:~ $ sudo apt-get install -y python3-serial
Reading package lists... Done
Building dependency tree       
Reading state information... Done
python3-serial is already the newest version (3.4-4).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 python3-twisted : Depends: python3-twisted-bin (>= 18.9.0-3) but it is not going to be installed
                   Depends: python3-service-identity but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Run that as sudo

11

Sounds like your package installs are messed up. Please can you paste the output of

$ python3
>>> import serial
>>> serial

Also, have a look towards the end of /var/log/dpkg.log. This might give some clues. If something went wrong during the upgrade there is probably more than just serial that’s broken…

Thanks for all the help so far,

This was all I got from import serial and serial.

Sorry but I’m not sure, how does one view dpkg.log?

Also tried running fix-broken instrall as sudo and here’s the output:

Hey,

Do

sudo apt clean
sudo apt update
sudo apt upgrade

Then try again

Sorry, on mobile. It’s raining lol

14

So I managed to get through the apt upgrade, ands it went through a very long update process (about 1h, did do it all which seemed encouraging).
It is now running the full update without too many errors.

Still getting the serial error on the emonhub log.
Tried running Python3 import serial, serial. and this is the output.

I’ve never seen this error. I think your SD card is toasted.

That looks like the right serial module. You could see what it says if you enter serial.SerialException or even serial.Serial. You should get sensible outputs, not exceptions. I suspect this is a side-effect of the previously mentioned trip of the SD card through a toaster…

We can probably get things working well enough to make it go again and rescue the data, but if you can replace the SD card I would do that. It could be that this was a one-off power glitch during an update, but I would be inclined not to trust this card any more. Sorry.

I’m in agreement.

Highly likely, but stop using the card.

Good point. If the power cut came at an inappropriate time, that could cause the issues. As I have said on numerous occasions, I’ve never had an issue with a Pi when I have simply powered off. IMHO, I think it is the associated spikes of a power cut that do for the cards. Personally all my Pis are behind a surge protector.

Thank you both @borpin and @bwduncan for the advice.
Pretty sure it was a corrupt SD card from something. I ended up doing a fresh install and all setup again pretty quickly and on the 2020 pi version now.

I made the mistake of ordering a replacement SD card not microSD so couldn’t import the setting, but all up and running again pretty quickly and all mainly done from an iPad!
