Power outage, and suddenly stops sending data to emoncms

[lukew151 (Luke Wakeling)]

Sorry, python isn’t my first choice language. I’ve just added many self._log.info("line x") to the source until I worked out what was going on.

The ERROR MainThread 'available' is coming from src/emonhub.py:93

The exception is from EmonHubAutoConf(settings). I’m not really sure what’s going on in here, but the reason it was crashing, was that the hardcoded file /opt/openenergymonitor/emonhub/conf/available.conf was in my case symlinked to /etc/emonhub/emonhub.conf and did not contain the [available] header. I may have upgraded the source many times, and my config file was from an older version?

Anyway, fixed by copying the example conf/available.conf to that hard-coded location.

I don’t know how my installation config got in such a mess, but the debugging messages did not really help to identify that there was no [available] header in my emonhub.conf.

Ah, there is a GitHub Issue open for this. @TrystanLea

And this

Mqtt interfacer gets no data

Turns out my Emonhub was not running successfully, because emonhub_auto_conf.py line 49 was looking for a hardcoded file named “/opt/openenergymonitor/emonhub/conf/available.conf” which in my installation was not there. Changed it to where my install lives, and emonhub seems okay PS. emonhub.py line 94 does not work as intended, calling sys.exit from here does not cause the main pid to exit. Is it waiting for interfacer threads to join maybe? I don’t know, but upon the an exception on line 92, …

I’m trying to revive my (simple) installation after downloading a recent version of emonhub.

Runs OK from commandline but not as a service.

Config file not found: "conf/available.conf".

I put a copy of available.conf in the same place as emonhub.conf
I see you also mention apikey but there is no such thing in my conf

Also tried putting autoconf = 0 in the [hub] section. Can start using command line (not service) but no data is being sent to MQTT.
