Open the Hue app, tap Settings > Accessories, then tap on the dimmer switch you’d like to configure in HomeKit. You now have a chance to tinker with the scenes you want to trigger or adjust the state of the devices you want the switch to control. Just tap and hold a scene or accessory to make changes. For example, if you want the switch to control your HomeKit-enabled LG TV, you can decide whether you want to turn it on or off, and whether to switch it to a particular input. Now, launch the Apple Home app (if it hasn’t appeared already), navigate to the dimmer switch you want to customize (look in the room where it appeared in the Hue app), then long-press the switch’s icon.

Scroll to the bottom of the screen and tap the Set up in Apple Home link. When you do, a pop-up will appear, warning that you will “remove your current configuration” if you set up the switch in HomeKit. Go ahead and tap Set up in Apple Home again. (You can always change your mind and set up the dimmer switch in the Hue app again, although you’ll have to re-do all your Hue configurations.) Second, configuring a Hue Dimmer Switch in HomeKit means giving up all Hue configuration options, including the ability to set up time-based light scenes as well as second-, third-, fourth, and fifth-press options. While HomeKit can configure double- and long-press options for some smart switches, the Hue Dimmer Switch isn’t one of them. Likewise, while HomeKit can configure time-of-day options for Hue button presses, it can only set a single time-of-day option instead of multiple ones (i.e., for daytime, nighttime, and so on), rendering the feature essentially useless. Want the scenes or devices triggered by the button press to turn off at some point? Just select an option from the Turn Off setting–anything from Never to After 4 hours.

You’ll now see fields for each button on the switch, labeled “Button 1,”“Button 2,” and so on. Tap a field for one of the buttons, then tap Add or Remove Accessories and Scenes.
