@mike.maxwell , not sure it is related, but there have been some very similar threads about this on the C5 with recent firmware updates. I am not positive they are related, but what @chacquie is having happen is quite similar to the symptoms I have been having. The main gist is that I get no response at all from the locks, no logs, no appearance that the hub even sent the commands with debug logging on. I have been working with BobbyD about this, but no progress so far. I would be glad to PM you further details if needed.
