Hi, Is there a place to configure the clientID in the MQTT since my broker only support V3? It's the -i option in mosquitto_pub CLI https://mosquitto.org/man/mosquitto_pub-1.html : -i, --id The id to use for this client. If not given, a client id will be generated depending on the MQTT version being used. For v3.1.1/v3.1, the client generates a client id in the format mosq-XXXXXXXXXXXXXXXXXX, where the X are replaced with random alphanumeric characters. For v5.0, the client sends a zero length client id, and the server will generate a client id for the client. Thanks, cz
