Hi have these 16 devices right now, 13 of them located on the same floor as the hub. I'm a recent owner of zwave devices, so I don't understand some things:
Why am I not able to control device 0x0B when I can perfectly control device 0x0F which is farther from the hub?
But if I physically change the status of that device, the hub is receiving the status changed message. How does this makes sense at all?
How can I change the security to NONE? That would improve the communication right?
0x10 and 0x11 are both Qubino flush shutters but that have different Security. Knowing that I did the same pairing procedure how is that possible?
Also, some times I got a device with status PENDING, I run the repair and it completes successfully but after that the node is still PENDING.
Finally I don't understand some routing as they are connected with farther devices when they have closer ones to connect, but I guess that is some kind of zwave magic that I don't need to understand right?
I would love these questions to be answered cause I am in the beginning/middle of my zwave journey and I'm even considering changing my hub as a desperate measure.
I have seen that sometimes a device will pair with no security if there was some sort of issue with the inclusion process - maybe it's corrupted or incomplete in some way. Notice that the network speed is slower than most of the others at 9.6. It's hard to tell though. I would consider removing and pairing that one again as well.
As far as other suggestions - pair the devices with no security first and then other issues if there are any will be more apparent.
I think you should let it settle for a few more days to see where the routing ends up. If you keep having issues report back. I don't think you need 2 hubs right now - indeed the general consensus at HE is multiple hubs are usually not required.
edit: keep in mind slowness/delay can be caused by other things like apps and drivers as well. Even though 9.6 is "slow" it is still within spec.
Although the devices are responding quite good, there one thing I can't understand still. I've noticed that sometimes the devices send a huge amount of consecutive power reports, when the report interval is 8hours.
Also, the farther devices seem to have a particular problem: when I switch them on for 2 seconds and then switch them off, it usually takes a lot of time to respond to the second instruction. Does it have a logic explanation?
