EmonBase - no inputs - problem with MQTT?

[jb79]

Hello!

After some years my setup with the Raspberry PI (data on harddisk) an serveral EmonTX nodes started to make trouble, so I decided to set up new software. I installed the latest available EmonPi Image (May 2016) did all upgrades on the command line and set up the rootdir to the harddisk.

The raspberry booted up and I was able to create a new account for emoncms.

The problem now is, that I don’t get input data in emoncms.

I corrected the speed for RFM12PI (V2) to 9600 and set up the data of one of the nodes (it measures an analog value and the temperature). A look into the emonhub log view shows the following:

So that looks like I receive the data but it’s going nowhere because of connection problems with the MQTT Server.

if you did a apt-get update && apt-get upgrade (or apt-get dist-upgrade) you may have a new version of MQTT and may have this issue.

MQTT Log files

I have just set up a Raspberry Pi with EmonCMS (mostly) following the instructions on building the SD card and I ran into some troubles with Mosquitto not starting (even though the service status was running…). It took a bit of hear pulling but turned out to be that I needed to create /var/log/mosquitto and set the owner as with the other services (in rc.local) So my question is why doe the emonSD image not need this change, or to phrase it another way, what step did i miss ;-)? FYI the versio…

Mosquitto not starting after emonSD update & upgrade

Hello, I have purchased the pre-loaded SD card for my RPi 3, a RFM69, and a emonTx. The emonTx CTs are all hooked up and it is plugged in. I have followed all of the steps and trouble shooting tips, but it appears that my emonBase (updated today) is not connecting to the emonTx: tail /var/log/emoncms.log 2016-09-21 01:40:40.000|WARN|phpmqtt_input.php|Not connected, retrying connection sudo service emonhub status ● emonhub.service - LSB: Start/stop emonHub Loaded: loaded (/etc/init.d/emonh…

Hello!

Thank you for your reply, yes, I did the update/upgrade after installation, so my mosquitto version is 1.4.10.
In the meantime I tried the quick & dirty version, downgrading mosquitto the following way: sudo apt-get install mosquitto=1.3.4-2
Then Emoncms is getting data from the configurated node.
After that, I upgraded to the latest version again, to see if the problem could be fixed.

It took me some time to find out, that /etc/rc.local had to be modified as described in MQTT Log files

To finish, a reboot was performed, now I get the measurements, now some work has to be done to configure all my nodes.

Thanks for confirming that the issues is with the latest version of nosquitto. Once I have tided up and added the log rotation I will create a PR for the fix.
