Setup, Configuration and Use Beginners

Yes, absolutely :slight_smile:

  1. I subsribed to several topics using mqtt.fx, which optically indicates if msgs are retained.
  2. Subsribed to a topic using mosquitto_sub. It ruled out there’s now retained msg left.
  3. I’m running Arduinos that most of the time sleep. When they wake up, they subscribe via MQTT in order to know what to do. This doesn’t work anymore.
