You have a lot of switches but is good but can also be slightly problematic due to the way the mesh works. A couple of things to note, you just need one buffering device between your lock and your hub, too many and you see other issues. Z-Wave a limit of 4 hops, so that’s good as it may not end up routing endlessly, but then again you need to check if your lock is taking too many hops. Second thing to check if which devices it’s using to hop. Some devices work better than others at buffering/repeating. For example the older Z-Wave GE switches were notorious for hanging, dropping packets and creating havoc with the mesh. The newer Z-Wave Plus models are much more stable. Some Monoprice are excellent. Others may be a mixed bag. If you have a “bad” switch along your route then it may explain what’s going on. The good new is that you can find out which switches are being used in your lock. See this post for details. If you do find it routing through too many switches or one you don’t like, the Z-Wave repair and exclusion buttons are your best friend to get the setup you like (it’ll take time but it can be done).
