I successfully synced all my Philips Hue settings to the Home app (HomeKit) today (Dec 31 2022). Here is the steps I got to work:
- Remove the Philips Hue Bridge from HomeKit by: Open Home App, click Home Settings, click Home Hubs & Bridges, choose remove Hue Bridge.
- Open the Philips Hue app, and configure the Philips Hue lights as you want them.
- In Home App, add Hue Bridge to HomeKit. Exit or abort all the configurations of individual lights, when Home app offers to configure your lights.
- Open Philips Hue app, click "SETTINGS" in the menubar at the bottom, click "Voice assistants", click "Siri & Apple Home", click the round "Settings" inside the Siri & Apple Home menu, and click "Sync setup to Apple Home".
- Open Home App again, and voila, the light and room settings are synched over.
Switches and other accessories
- Having completed setting up my lights, I added my switches (accessories) in the Philips Hue app.
- In the Home App, the switches were listed as "Accessories Added to Home" and on the main/front page in Home App, it asks "Set Up Accessories". I clicked on "Set up Accessories" and added the switches to their respective rooms.
- In Home App, I then went to each room, clicked on the icon for the switch and set "Add to Home View" and "Include in Favorites" as UN-selected, so that the switches are hidden in the Home App.
The above worked for me to get the main sync step to work: Open Philips Hue app, click "SETTINGS" in the menubar at the bottom, click "Voice assistants", click "Siri & Apple Home", click the round "Settings" inside the Siri & Apple Home menu, and click "Sync setup to Apple Home".
