I've been trying (and failing) to add a new Z-Wave device to the ISY.  I've gone through multiple remove/add cycles but get the same result as illustrated below:

Sun 12/26/2021 10:52:31 AM : Add Node failed: Cannot create primary node for new device

From the logs, it appears that the device is being added to the Z-wave network, but that the ISY is unable to create a new primary node.  Any ideas?  I'm running the following (device and firmware info):

I don't have a Polisy or other local polyglot to add an ISY Inventory nodeserver, but would be somewhat surprised if I've hit the 256-node limit. Any other good way to count?

In case it might matter, the device that first presented the problem is an alarm.com ADC-SWM150 water meter/shutoff, but I am seeing the same pattern with other devices that I have since tried, including an Aeotech Smart Switch 7. 

Solutions?  ... ideas?

Reboot ISY and make sure device is close to it

Thanks. Done both.  Same problem. 

Went on to delete some extraneous device nodes and got further on next add node try, but this time got a series of "too many nodes" messages after first three nodes added. 

Seems like the node count tallies more quickly than I would have thought.  Maybe all the subsidiary nodes of newer Z-wave devices?  Will try a PRO upgrade next.

That's probably the issue, if it's not you will hit the non-pro limit quickly with z-wave.

If you have Polyglot on Polisy or Pi there is a nodeserver called ISY Inventory that accurately counts nodes.

Resolved with Pro upgrade.

I concur with @MrBill, non-Pro node limit is easy to hit, particularly with some of the newer Z-Wave devices that result in many subsidiary ISY nodes. Based on a quick manual count, I’m carrying 30 physical devices that are Z-Wave and 22 that are Insteon (including 5 KPLs).
