We cannot really diagnose your network from remote, but you’re running a SW version that has network healing disabled, so likely the routes on your devices need updating but that does not take place.
I suggest migrating to latest testing milestone (2.4M4) as that comes with a new version of the zwave binding to have network heal enabled.
Take care to take action on zwave things after upgrading.
20 meters sounds about right - you would only get 100m under ideal, line of sight conditions, and probably only if antenna polarisation is aligned.
These drawings show 4 walls - what are these made of? If it’s brick/concrete, then I’d be surprised if it works at all. If it’s thin plaster walls, then it will work better. Somewhere I have some data on this, but RF propagation is not a straight forward science - especially with the low power, low efficiency antenna systems used on IoT devices.
I think the only real option is to build up your mesh to give the system more opportunities at routing the data. By this, I mean specifically to add more devices “in between” the troublesome devices. The more devices in the network, the better the network will be.
Note that these need to be mains devices - your current list of devices are battery devices, so they will not be able to route frames for other devices, so will not participate in the mesh as such.
I’m not sure that it will help much with this issue - at least not without improving the mesh, In general though I would recommend upgrading as it does have a lot of improvements over the 2.3 binding. As stated above, the heal is included in the 2.4 binding which might improve things if you have devices that can be used for routing, but within your current network, this is not going to help as the battery devices will not support the mesh network.
My z-wave switch is not performing quickly, changed from ONLINE to OFFLINE
is it a coverage issue ? poor aliexpress hardware issue ? openhab issue?
would you solve my headache ?
i want to underline my fibaro motion sensor in the same room works well

All sorts of - look at the market.
Roller shutters, plug sockets, …there’s even repeaters (mains powered actuators without any use except to route messages) although I’d always select a plug socket instead so it is of additional use.
