First, you must register on the Hue website. Then you need to link your Bridge to your Hue account. The next time you start the Hue app, go to settings and choose ‘log in to portal’. Log in to your account and you’re ready to go. Please note that you must be connected to your home network the first time you set up the out-of-home functionality. Also note that you will need a 3G/4G connection if you are not in range of your Wi-Fi network.
