Node Red and some MQTT feed issues ...

[Bruce Emsworth]

I have an Arduino reading time, temp and 3 analog inputs, feed those to MQTT.
All show up properly in MQTT-Spy and in the MQTT console. I have MQTT and Node Red with the Dashboard add on running on a Pi3

In V1 I only output the temp to a dashboard guage and a chart - worked a treat!

Now I have added the analog inputs. The values get to the MQTT queue, but the values don't show up on the dashboard. I have restarted Node Red (on a Pi3) and the browser (Firefox on a W10 PC).

Any suggestions?

Here is my flow .....

do they appear in the debug ?

how fast are you sending data ? (the chart in particular has known problems with quantities/speed of data)

[Bruce Emsworth]

The temperature is basically once a minute, but the analog readings are at the speed the Arduino can manage - so probably a burst of three readings in a few milliseconds. Good thought, I'll try slowing down the analog reading rate.
Thanks

OK tried introducing a 500ms delay for each analog reading - still not working!
Strange why it gets one set of values (temp) from MQ but not the others (analog) ....

Have you tried adding a delay node into it to allow through for example 1 message every 10 seconds, and then feed this into a debug node, so you can have a chance to read it and see if its a formatting issue?

delay node.... set to rate limit mode... and dropping intermediate messages.
