So today i’ve been fighting with OpenHAB for a bit.
It’s worked perfectly before, but now almost all the nodes if not the entire set of nodes start saying
‘zwave:device:72000c57:node4’ changed from OFFLINE (COMMUNICATION_ERROR): Node is not communicating with controller to ONLINE: Node initialising: REQUEST_NIF
And this has been going on for several hours now. The system has been slow to respond and most of the time lights do not respond at all.
What would be the fix for this? I’m using the latest OpenHABian and the latest OpenHAB 2.4.0.
I would guess that the issue is with your ZWave controller, since that’s the common link and your software hasn’t changed. What kind of controller are you using?
What happens if you unplug/plug it? That should restart the service. You can also do a soft reset from the thing properties in PaperUI if that’s easier.
I think that your ZWave stick might be failing. If you used a fresh SD card with a backup from a period when OH was working properly, the same issue shouldn’t immediately reappear.
I would start by uninstalling the ZWave binding to see if OH returns to normal. If other devices are fine, then you don’t need to start over completely.
If you confirm that it’s just a ZWave problem, you could try installing the ZWave 2.5 snapshot binding to see if that helps. If it doesn’t, then there’s a good chance you need to replace your USB stick.
Also, do you have HABmin installed? From other posts, it sounds like a lot of people prefer that for managing ZWave, and you can see a map of your ZWave network. Maybe it can tell you more.
What changed? I sounds like your devices are having trouble communicating with the controller. Have you moved or removed any devices, or moved the Pi? Healing or reinitializing the nodes may help. There is also a nightly network wide heal (IIRC at 2AM).
Did you upgrade to 2.4, or have you been using this version the entire time since including your nodes?
In order to troubleshoot this in depth, you’ll need to look at some zwave binding debug logs.
