Thank you oberkc for your assistance. It has all worked out (so far) to add my Insteon switches and plugs to Apple Home/HomeKit. I am using an Apple TV as my hub. As others have noted it does not add the Insteon dual receptacles correctly. Only the top outlet shows up in Apple Home, and even that doesn't do anything. If you try and turn it on it will revert back immediately on the screen to being turned off. I'm not aware of a complete list of instructions to add the Insteon devices on Eisy to Apple Home/HomeKit, so this is my suggestion: (1) Go to polyglot (PG3) and install the iox-matter node server, using an empty slot. (2) As oberkc said, go to the node server dashboard on Poyglot, and save a copy of the QR code that was generated. Note that if you delete and re-install this node server, a different QR code will be generated. This is the QR code you will beed to pair the Eisy with Apple Home/HomeKit. (3) Make sure the "Matter" device/node is "online" and has an "active" bridge status in the Admin Console list of devices. (4) Go to the Matter tab on the top edge of the Admin Console screen. Perform a "Synchronize" with "New & Deleted with Interview". wait for this to complete. This will create several pseudodevices with the names in format ZM XXX.1 Main, where XXX is a 3 digit number starting at 001. I believe these correspond to your Insteon devices. None of these pseudodevices will do anything if you try and turn them on or query them, but they should all be "Online" and "Active". (5) To do the pairing your iOS device might have to be close to the Eisy. I can't tell you how close, mine was about 6" away. The "Matter" bridge node described in (3) has to be "Active", Your Apple hub has to also be active. (6) Using your iPhone or iOS tablet open up the Home /HomeKit app. Tap the "+" sign to add an accessory. Scan the setup QR code you obtained in step (2) above. (6) If all goes well you will be asked to approve an uncertified device. Do it. (7) Reboot your iPhone or other iOS device to pull in all the Insteon devices into Apple Home/HomeKit. If you have any issues then reboot your devices - Eisy, IPhone, and Apple Hub along the way. If the Matter node server stops working on the Eisy then restart the iox-matter node server in PolyGlot. You might also want to synchronize UD mobile with your controller (Eisy) so you can see the status of the "Matter" node server. You may have to try this a number of time. As others have suggested if the Insteon devices disappear from the Home/HomeKit app, try restarting the iox-matter node server in Polyglot If you make a mistake and want to start afresh, delete the Matter bridge that serves as the basis of the integration between Eisy and Apple Home. It worked for me to delete the bridge in Apple Home (go to settings of any of the associated devices in Apple Home, where you will seen "Bridge"), delete the node and associated pseudodevices in the Admin Console, and delete the iox-matter node server in Polyglot. Then reinstall the iox-matter node server. Start again at step (1) above, Forgive me for repeating anything which is already out on the Forum. I have had difficulty finding answers to my questions about this. I believe that I have erred in trying to use Google searches to find out information about this topic. The standard Google AI search is of course generally useless, as it overgeneralizes and throws together irrelevant information. Perhaps it hallucinates information. Then, the basic Google search does not seem to utilizes content in the UD Forums very well. I now believe that I should always go to the UD Forums directly,
