A sensor (BME280 on a NodeMCU) is publishing data to this MQTT broker, and I can see the data being published successfully using MQTT Explorer running on a separate PC. For whatever reason, I cannot get the mqtt in node to connect to this broker. Create a device called my-mqtt-device that uses an autogenerated symmetric key.
