If you are an Android user:
Yes you can! You can simply pair with the Aurora through the Nanoleaf app and control all Aurora functionality. To do this, you must be on the same WiFi network as your Aurora.
If you are an iOS user:
Only one iOS device can be paired with the Aurora through the normal pairing procedure. However, more users can be invited to your Home which will give them control over the Aurora functionality. Please refer to the How to invite users to your HomeKit Home section for further details on how to add users. Added users will have complete control of the Aurora's functions but will not be able to add or delete Auroras, Rooms and Scenes in the app.
