MQTT Mosquitto Broker and NodeRed - Not Working

Third party integrations Node-RED
1

Running hassio on a RPi. After some effort, I got the Mosquitto MQTT Broker installed and running (at least I think I did based on log entries) by following the installation instructions on https://www.home-assistant.io/addons/mosquitto/. My problem is that I cannot get the mqtt publish and subscribe nodes to work in NodeRED. I configure them to use the MQTT Broker, publish/subscribe to a simple topic (like “sensors”) but when I use an inject node to inject a basic string into the publish node, the subscribe node doesn’t output anything to the connected debug node. I even followed a helpful YouTube video on using MQTT nodes to a T (https://www.youtube.com/watch?v=XDrwgMSQrEY) but no luck.

Thoughts/suggestions appreciated.

Hi,
I just did the installation and it works. However, you have to do exactly what is said here https://www.home-assistant.io/addons/mosquitto/. You need a user and the acl. Without those, it was not working for me.
Hope it helps.

Thanks. I finally got it working. I wish I could say what I did but really have no idea how I got it to work. I uninstalled it and then reinstalled and presto it worked. Maybe I had a typo somewhere in the configuration. Oh well.
