Today I successfully established cloud connection by installing and configuring cloud service binding.
Running Openhab 2.3.0 with addons from snapshot (2.4.0) on CentOS 7 64bit version
Problem: Noticing a big lag between the command issued from end device (like phone or tablet) to the point it is received by end IoT device (communicating Openhab<–>Mosquitto MQTT binding). if the end device is connected to local (instead of remote/cloud) there is still a little lag but it is not as significant as when connected to cloud. I think it is not normal.
Any help pointers to further troubleshoot?
Please note masked UUID I am noticing few occurrences of following entries in the openhab log file
