Join Inovelli Lzw42 insecure

Just wanted to share a method I've been using to successfully join LZW42 bulbs insecurely to my C-7 hub using the Z-Wave PC Controller and a USB Z-Wave stick.

Disclaimer:

Proceed at your own risk.

Prereqs:

  1. Z-Wave PC Controller version 5.39 or greater
  2. Compatible USB Z-Wave stick. I'm using an Aeotech Z-Stick Gen5
  3. It's helpful to run the PC Controller from a laptop so you can be in close proximity to the bulb being added since there is an element of timing involved.

Instructions:

  1. Pair your Z-Wave PC Controller as a "Secondary Controller" with your Hubitat C-7. Inovelli has instructions for doing this with a Smartthings hub for the purposes of firmware updates. I found that the process both for joining and for updating FW works for me with my Hubitat C-7. You can review them here: https://support.inovelli.com/portal/en/kb/articles/how-to-update-device-firmware-z-wave-smartthings-secondary-controller-method
    To Summarize this process:

    1. Put your Hubitat in Inclusion mode

    2. From the Z-Wave PC Controller network management page click "Classic Learn Mode"

    3. On the Hubitat you should get the S2 security pop-up. Click OK

    4. The PC Controller will display a 5 digit pin. Enter this pin on the Hubitat when prompted.

    5. If successful you should now see a list of all your devices in the PC controller and your ready to proceed.

  2. If the LZW42 you would like to join has already been added to your Hubitat hub with S0 you should first remove it using the hubs exclusion mode and then confirm it has been removed from your device list.

  3. Make sure the device you'd like to add is not powered

  4. In the PC Controller network management page click the Add button. A status bar will appear at the bottom with a red "Abort" button. I like to place my mouse cursor here

  5. Power up the LZW42 bulb. Typically the bulb will flash twice quickly then there will be a pause followed by a third flash. Immediately after the third flash click the abort button on the PC Controller. I find this interrupts the security handshake and includes the device insurely.

  6. Verify you have a new device listed in the Z-Wave PC Controller list and that it's name is not preceded by [S0]. If it is or the device was not added try using the PC Controller Remove to exclude the device before attempting to include again.

  7. If you have multiple bulbs you want to add repeat steps 2-6 until all devices are added.

  8. At this point the LZW42s have been added to the Z-Wave network but will likely not be visible in Hubitat. To refresh the list I've found the most reliable thing to do is reboot the hub using Settings -> Reboot Hub

  9. After the reboot navigate to Settings -> Z-Wave Details. In this list you should now have a number of new devices with a "discover" button in place of the name. For each of these new devices click the "discover" button. My experience is that sometimes the details page will refresh faster than the discovery process. If you wait a couple sec and reload the page you should now have a recognized device.
