MQTTool

I’m just starting to understand the MQTT side of smart devices and this app I had connected and sending & receiving on all first attempts. Very user friendly!

You need to push on the text in the body of the page for both “connect” and “publish” rather than below on the menu bar. These could be highlighted or a different color and In bold to make it a little nicer. But it works great! I tried it for publishing and subscribing to a Mosquitto MQTT broker on a Raspberry Pi and had no troubles. Great app.

I was spending a but of time checking my mqtt broker until I finally realized I need to tap on the “connect” text in the main window instead of the “connect” icon at the bottom left of the screen 😳 Once that was sorted out the app works nicely 👍
