I have figured out a work around for this, at least when using the Aeon Z-Stick Gen5 (white). Maybe it does or does not give a clue to the root cause of the problem. Workaround for secure inclusion failing when a certain threshold of nodes exists in the network:
- Download Zensys Tools (link)
- Download Aeon Backup tool (link)
- Copy your network security key from Habmin
- Shut down OH2 and remove the Z-Stick
- Place the Z-Stick in a Windows PC
- Perform a backup of your Z-Stick following the directions in step 2
- Open the Zensys Tools, connect to your Z-Stick
- Highlight your Static Controller node (should be first in the list)
- Go to the Command Class tab on the right, select COMMAND_CLASS_SECURITY_V1 for the Command Class, NETWORK_KEY_SET for the Command Name
- Enter your key into the Network Key byte field, replacing the “00” with your key you copied from OH2
- To test, go find a working secure node and click the Node Info button. You should see all command classes and the log will indicate that the node was “added to the secure network”. So far, so good. If you don’t get “added to secure network”, then the query isn’t working and the following steps won’t do you any good.
- Click “Add node”
- Start the inclusion on the device you wish to add, ensure the device is within a few feet of the Z-stick. You should see an indication that this device was added to the secure network.
- Shut down the Zensys Tools, move the Z-stick back to OH2, move the device you just included to within a few feet of the Z-stick
- Start OH2 and go get a snack. Wait 20-30 minutes for the binding to settle down and you should see the new node you added in your Inbox, identified and waiting.
- Add the node to OH2 and validate that security is checked. Your device should now be working.
The only issue I am having is that the binding doesn’t seem to want to enumerate all of the channels. For the particular device I am using the only channel I need is exposed by default (Barrier State), and the controls work. I haven’t figured out how to get the binding to discover the remaining channels.
