Solution

  • Make sure SIteController runs, check by running SiteController/run_SiteController.py status on your device.
  • Error message on_connect - rc: Connection Refused: not authorised. implies incorrect MQTT credentials. Verify the configured user and pass in config/SiteController.cfg
  • Error message error: [Errno 111] Connection refused implies that Site Controller can't establish an outgoing MQTT TCP connection. Check your firewall settings and test for a successful outgoing connection with telnet (see below).
  • Error message no route to host implies that the broker host cannot be reached, either because the host is offline or you have no network connection to the host. Test if you can reach the MQTT broker as configured in config/SiteController.cfg,
