Regards, Hi If I change the server to the IP of the 1st board I can connect to it. For connecting to InfluxDB 1.7 or earlier instances, use the influxdb-python client library. Ive written 2 scripts to use the broker to continuously send screen shots of one machine to all connected clients. In both cases the connect and subscribe (mid checked) are successful. If I use an external broker address everything works fine. The script is probably ending before the message arrives increase the time.sleep to 20 secs Coming from requests ? log: Sending CONNECT (u0, p0, wr0, wq0, wf0, c1, k60) client_id=bpython1 Apdex, response times, network, errors of (login and get a session, connect to the broker, subscribe to the topics and publish messages), Hi rgds python client, Thank you Steve!

They use simple and natural syntax and provide formatted and colorized output. mqttc = mqtt.Client() print(message received , str(message.payload.decode(utf-8))) to create an instance of the Client class with use Rgds Btw I have a small question: As I can see now, callbacks works only if the method signature is the same as it is required by the paho lib, so this doesnt work for me: https://hassancorrigan.com/blog/install-nodejs-on-a-raspberry-pi-zero/ ConnectionRefusedError: [Errno 111] Connection refused I want to know if it is possible to know if an mqtt client with a particular id has disconnected.
