Cumulus Support

It sounds like you are getting more than just 'sensor contact lost', you are getting the 'USB lockup' problem. Please zip up the diags folder and attach it.

...and the failure to output the "lost sensor contact" code?

Have attached relevant files.

The interface to the console had apparently locked up (it wasn't responding to requests for data) so the console required a reset. You might want to try the 'Synchronise Fine Offset reads' setting, a number of people have found this helps to avoid the problem. I believe I have now found the issue which causes the main window to be non-responsive when Cumulus starts up and the station doesn't respond, so I can fix that in the next build.

There are three occurrences of 'lost sensor contact' reported by the console this morning, at 02:31, 03:03, and 03:35, and in all cases the condition apparently only existed for one read, so 10 seconds later the flag would have been cleared. If the web tag had been processed in that 10-second period, it would presumably have had a value of '1'.

There was no occurrence of 'lost sensor contact' at 05:15, that's when the console stopped responding completely.
