I wasn't as helpful as I should have been on my reply, and should have asked.. What is the firmware on your lock, and what model is it? Anything on the BE468/469 locks before 7.2 (although some here have 7.1) is sketchy. If your lock is running 6.8, replace it. That version is running garbage firmware. I had some issues with my older BE469s on Smartthings. They didn't report reliably and the Z-Wave mesh would slow to a crawl for several minutes if I attempted to lock both locks at the same time with a rule.
The devs looked into it and determine both locks were flooding the network with unparseable messages. I replaced them both and had no further issues with reporting or slowdowns.
On many Schlage locks the firmware version is printed on the same label as the factory codes.
