Nodered MQTT (Sparkplug) flow

Maker

Hi,
I just wanted to share a fully working sparkplug flow for those of you considering using nodered as an Ignition interface.

Here you can test inputs, outputs, DBirth, DDeath, rebirth and probably more...

I suggest using NPM and installing sparkplug client first like this:

npm install --unsafe-perm sparkplug-client
npm install --unsafe-perm node-red-contrib-sparkplug

I am not completely sure, but my assumption is that you get the latest sparkplug-client this way. contrib-sparkplug is a bit outdated...

Hi!
Everything works well, except that I get "ReferenceError: options is not defined" error when sending a DDEATH message. No errors when sending DBIRTH or DDATA messages.

I'm stumped! Any ideas?

Hi,

Reviving an old thread.

I used the above Flow and modified it somewhat. It works well, but how can I know if connection to the broker is lost?

image

I manually disabled the MQTT Distributor. The sparkplug node sees that it is lost, but no message is sent (debug node did nothing). Is there a way to pick that connecting status up and do something with it?

Thanks,
Deon

Just add the “status” node to your flow. It’s included by default in Nodered.

That was easy. Thanks.

Did you try to install the latest NPM libraries first?
