Hey all,

I'm constantly seeing this pop up in my event log almost every time a Z-wave device sends a report:

11/12/2016 11:14:15 AM : [ZWAVE-DB        ] Unexpected NULL database for uid=16 0x10

Sat 11/12/2016 11:14:15 AM : [ZWAVE-TX        ] [01030002FE]

Sat 11/12/2016 11:14:15 AM : [ZWAVE-RX        ] ACK

Sat 11/12/2016 11:14:15 AM : [ZWAVE-RX        ] [0125010205001DD2]...

Sat 11/12/2016 11:14:15 AM : [ZWAVE-TX        ] ACK

Sat 11/12/2016 11:14:15 AM : [ZWAVE-NODE-SYNC] ---- Start Processing Z-Wave Node 16 (0x10) ----

Sat 11/12/2016 11:14:15 AM : [ZWAVE-NODE-SYNC] -- Finished -- ISY/Z-Wave Node Sync --

 

 

 

While the Zwave-TX and Zwave-RX might be a different message (usually its whatever z-wave report is being sent), the bold faced three are always there.

I do know which device 16 was.  It was a water leak sensor that stopped responding.  I correctly removed failed node... but it still haunts me.

What can I do about it?  Have tried heal, synch, repair on all of my z-wave devices.  No luck with anything.

Same here. I excluded a couple of thermostats and now every time I do a heal network I get the unexpected NULL database error for the two nodes that were the thermostats. Tried sync'ing nodes but still get the error. I'm on 4.5.4.

Hi Guys,

 

I'm not sure what is going on, but my guess (just a guess) is that the old devices somehow remain in some of the Z-Wave routing tables.

 

If you restart your ISY does the problem go away?

Restart doesn't make any impact at all.

I should have clarified that question, did you try powering the ISY on/off?  If not, give that a try.

 

Could you please do the following with the event viewer at level 3 and post the results:

 

1) Synchronize Nodes 

2) If an ISY node appears for the device, right+click the device and do a Z-Wave -> Remove Failed Node

 

For whatever reason, the dongle still thinks device 16 is still in your network.  This usually happens if a device is factory reset before it is removed/excluded from the network.

Tried all, doesn't make a difference.

FYI - Node doesn't appear anywhere for me to remove.
