It's -looks- good but for some reason, I can't connect to my HiveMQ cluster. When I test my connection on the Broker Access Configuration page, an error message eventually pops up that says the connection failed. There seems to be more information in the message but I can't access it. My first rating was so so but I figured out my connectivity issues and I am very pleased. I do wish I could change the size of the graph on the dashboard though.

The best MQTT tool out there, period. Works great every time, doesn't disconnect, lots of features. Of course, don't forget to add to unrestricted apps, and allow background data usage and remove it from duckduckgo app tracking (or whatever protection vpn you're using). Cheers! Suggestion: for alarm type notification, keep the notification undismissable. Otherwise if you dismiss it, there's no way to stop the sound unless you go in the app and disable+enable the action item.

Works as advertised. Nice features and well thought out. Useful tool for testing my IoT projects but it's a bit of a battery hog accounting for 7% which is quite significant. To be fair, if I used my phone like a teenager, that number would likely be overshadowed by other apps.
