You may use your POP button / switch with the Apple HomeKit, this is achieved entirely through the Apple Home app. You must use a 2.4Ghz network in order to use POP with Apple HomeKit.

1. Set up your Apple HomeKit and any other HomeKit accessories you may have, before adding POP.
   (If you need help with this step, please refer to Apple support)
2. Open the Home app and tap the Add Accessory button (or + if available).
3. Wait for your accessory to appear, then tap it. If asked to Add Accessory to Network, tap Allow.
4. With the camera on your iOS device, scan the eight-digit HomeKit code on the accessory or enter the code manually.
5. Add information about your accessory, like its name or the room it's located in. Siri will identify your accessory by the name you give it and the location it's in.
6. To finish, tap Next, then tap Done. Your POP bridge will have a name similar to logi:xx:xx.

Some accessories, like Phillips Hue lighting and Honeywell thermostats, require an additional setup with the manufacturer's app. For up-to-date instructions on adding an accessory, directly from Apple, please see:
