Trying to add a couple more devices but get an error cannot add device reason 1 . Cannot remember what the number was but for some reason 256 nodes stick in my head. Would I just need to update my ISY994i ZW+ to the Pro version module?

 

Yes...... It happened to me a few years ago.

If you have a Polisy, then use the Inventory nodeserver to identify how many nodes you are using.

If you don't have a PRO. Adding that feature would increase the number of links. I believe it also increases the nodes.

If you have the PRO already. Then you have hit the limit.

You could ask  UDI in a support question. If they don't find it here.  https://www.universal-devices.com/contact-us/

You just need to buy Pro upgrade.  It's a soft upgrade, no hardware required.  

 

Great thanks everyone that was the issue. The pro upgrade fixed it all.
