I dont use things file for the Xiaomi brigde… I use PaperUI.
From your log file though, I would assume it´s a communication error. The gatway is communicating through WiFi (2.4Ghz as far as I remember). Check that your communication is stabel to the Xiaomi gateway.

Although your problem may seem similar to the original post, it is an older post and it may be best to post a new thread. In this way, folks who can help you will be drawn to look at the new thread and not ignore this one because it is old. Also, please to be sure to post your operating system, platform, version of OpenHAB, item files, things files if used and logs of the problems you are experiencing.
Thanks

The Mi Smart Home binding page example is showing pollingInterval=6000

6000 not 600/500

I suppose these are milliseconds, so 500 would be every half second. Might just be too often. I have not had any issues with the default 6000. Maybe try that as well.
