MQTT - more messages than expected with overlapping topics

Have a search for previous posts from me that mention overlapping subscriptions to get the full explanation.

Is this the post you refer to Nick?

@knolleary

It's a known issue in Node-RED when you have overlapping subscriptions with certain broker implementations. The full explanation is too much for me to tap out on my phone, so suffice to say it's known and won't be fixed.

No thats fine - I was unsure if I had caused the issue or if it was somehow related to recent mqtt version upgrade.

I can carry on assessing MQTT V5 and how it might be implemented in node-red. I hope to present something soon - just needed to get this out of the way as it has had me stumped for some time.
