So, I just started with HiveMQ but am already Subscribing / Publishing topics from both an ESP32 and Android App. Got a couple of questions:
Previously I worked with https://io.adafruit.com They have a really nice control panel and dashboard capability on their web site. I can see all topics in my account (they call them “feeds”), what their latest values are and when they were posted. I can delete topics and create new ones right from the website. The dashboards can be configured with controls (switches, sliders) to drive topics as well as graphs and other displays of topic data. So, my question … Does HiveMQ have this web control / dashboard feature hidden somewhere?
I don’t really know what a “TLS Certificate” does, why I need one, or how to make one. But, I found out that I do in fact need one to connect to HiveMQ from my ESP32. After some digging, I found one hiding here:
It would be nice if it were easier for beginners to find that. Say in the “Getting Started” section.
But anyway, my real question is … why don’t I need a Certificate to connect to HiveMQ from this Android App:
I just give it my Cluster URL, Port 883, and login information. It then connects to HiveMQ via TCP-SSL without me specifying a “Certificate”. Why does that work?
