Weird topic in MQTT explorer - am I spamming broker?

Thank you, yes you’re correct about the topics but I like it to be organised for some reason.

Millis timer is also a great idea I will implement.

I need to think through the logic of what I need, I think overall I will have it detect every noise over a certain value, then I will have a gate node to allow/block the flow depending on whether it’s a barking episode or another noise.

Not perfect but detecting the barks seems quite difficult from my searches.
