Can't get feeds from MQTT working No matching MQTT topics!

Emoncms
1

I can’t get the MQTT message format right so that emoncms accepts the inputs.
This is my emon build configuration:

emoncms settings 20170828
emoncms settings 20170828919×1009 132 KB

This is what the log is telling me

emoncms logger 20170828
emoncms logger 20170828916×403 111 KB

These are the topic tags I am using

/emon/PMon10/Apparent/Outside_Lighting
/emon/PMon10/Power/Outside_Lighting
/emon/PMon10/Apparent/Downstairs_Lighting
/emon/PMon10/Power/Downstairs_Lighting
/emon/PMon10/Apparent/Extension_Lighting
/emon/PMon10/Power/Extension_Lighting
/emon/PMon10/Apparent/Cooker
/emon/PMon10/Power/Cooker
/emon/PMon10/Voltage
/emon/PMon10/Apparent/Kitchen_Plugs
/emon/PMon10/Power/Kitchen_Plugs
/emon/PMon10/Apparent/Outside_Plugs

The data consists a single numeric value per message

Any help would be gratefully received

does the topic need a trailing “/” ?

More information, in the trace below the I have added quotes around the topic and the data strings (these don’t appear in the messages to the MQTT broker…

Does this look OK or have I misunderstood the required message format?

OK I had misunderstood the format, this seems to be sent without causing the errors logged above (ignore quote marks)
