Having a strange problem on a C5 hub, recently the zwave has been stopping for no reason. After a reboot all works fine but after a while it stops. I have been keeping up with the updates so not sure it that might have caused something ?
When you say "the zwave has been stopping" do you mean that both of your zwave devices stop responding to commands issued from the devices tab, they stop working in rules, the zwave radio shuts off, or something else?
Thanks for the response, its a strange one. The two devices I have on the device are fibaro 1. Fibraro Implant and 1 Led strip.
When it stops working the zwave settings page shows no devices and the implant sensor stops sending / receiving temp settings, however the led strip comes on.
If I reboot the hub everything appears again and works, the last time it ran for about a week but this time 4 days and the only thing that happened in or around when it stopped working was that I rebooted the C7 device which is connected via a mesh.
Wow... the devices totally disappear from the zwave settings page? Do they disappear from the devices tab as well?
I'm wondering (but admittedly guessing) if this might be an indication of database corruption. A backup to a local file followed by a soft reset and a restore might help (or might be a waste of time but likely won't hurt).
yep they just disappear completely, you can still see them from the devices page but if you try to refresh or do anything with them nothing happens.
I tried disabling the zwave and enabling before a reboot with no change, I was thinking maybe temp as it can get warm where the hub is but the strange thing is one device still sort of works.
I only use this hub for integration and the C7 being the primary for all my main devices which is working fine, I did add a few apps recently which I don't normally do. I have now removed them all but one (MQTT client) If it happens again I will remove this app also.
I would like to get a look at the zwave logs on the device just to see why it shutdown the zwave, also I could be wrong about the zwave stick shutting down as the only real information i have that points at zwave is the settings / zwave being blank.
I wonder if a restore will do it, should I restore from a known good backup or just grab a backup now and restore ?
I also dropped a quick email to support just to see if they could do a quick remote diagnostics and shed some light on the problem from the logs, @bobbyD might be able to work some magic. The C5 hub has been solid however it is getting on in life so maybe i need another C7
Have you tried shutting down the hub, and removing power for 30 seconds? This will reset the zwave radio on the C7, not sure if the same thing happens on the C5. When you yank the power do it from the outlet end, not the delicate little micro USB connector on the hub.
Rather than just do a restore, I think you need to do a soft reset after you download a backup locally. Apparently when the backup runs, the backup itself is scrubbed for errors. By doing a soft reset you wipe the database and ensure a "clean" restore. Just doing a restore does not necessarily have the same effect if the database is corrupt. Though maybe this is more of a zwave database issue than an HE issue? Not sure.
I doubt repair will help. Based on your description, you are likely dealing with a hardware malfunction on the stick side. Disappearing devices on Z-Wave details page, usually means that the radio went offline. Will follow up on your ticket shortly.
I've just come to this thread with exactly the same issue with my C5 (184.108.40.206)- the Z-Wave devices stopped responding completely at approx 12pm UK time, the Z-Wave page on the hub showed the devices in the list, I rebooted the Hub via the Web GUI and now the Z-Wave page is blank.
