In runtime 183 of openhab.

I had this sensor working.
Batteries died
I changed them

Now it wont communicate
It’s added to the zwave network, but neighbors list is empty
Looking at the log i see this

2016-11-10 18:10:22.322 [ERROR] [NodeNeighborUpdateMessageClass] - NODE 27: NodeNeighborUpdate FAILED

Any ideas why this is happening?

Thanks

The error isn’t that the neighbour list is empty - the error is that the request to get the list has failed. It’s hard to tell what’s going on without seeing a debug log, but I would say there’s something wrong with the dongle. Try resetting it, or removing it from the PC and plugging it back in again to see if that helps.
