As of a couple of days ago, I’ve been having major issues with Zwave on my OpenHAB installation and so far, no amount of software updates, driver updates etc has helped.
I woke up over the weekend to find that something had died at approx 2:40 AM as none of my graphs were updating and none of my zwave plugs were listening to on/off commands, the zwave controller itself (a new z-wave z-stick gen 5) was also showing a ‘bridge error’ within OH.
I tried restarting the service and the OH debug log was constantly scrolling with what looked like looping text where by it was trying to send PING/ALIVE requests and getting something else back. Also, nodes kept showing as ‘initialising ping’.
I thought I had made progress today bu opening the zstick up in zwave controller and re-clicking ‘get info’ on every node as all the node classes were missing however upon plugging the zstick back in to my server that runs OH, I’m now getting I/O errors followed by something restarting but it ends up being an endless loop.
I read in the forums that I/O errors can be related to USB port or driver issues so I have tried changing from the servers onboard USB port to a separate USB3 controller and I have also swapped to a different driver for the zstick but the issue persists.
Can anyone offer some insight as to how I can resolve this issue?
Have you tried plugging the z-stick into another system to identify if it is an issue with the motherboard or the z-stick?
Also side note I believe there is an issue with USB3 ports and the gen 5 z-sticks from Aeon, could be recalling a different issue it was with folks using the Raspberry Pi4 when it first came out.
If it stops blinking a few minutes after a reboot, you have possibly been struck with the aftereffects of a zombie node, but that problem did not have any I/O errors in the log, so it might not apply to you.
