I am running btmon.py to upload data from 3 ECM devices that I have connected.  I was able to get discovery working and data is reporting every 30 seconds no problem.

However after running for about an hour I get a notification that my devices have gone offline, even though the devices page is showing realtime data showing up from all 3.  If I restart btmon, the devices go back online and eventually fall off again.

Any suggestions?

I just noticed the other thread on this topic.  What frequency of data collection should we use?
