The first thing you need to do is register on the www.meethue.com website. Then link your bridge to your hue account (My Hue). The next time you start the Philips Hue app, go to 'Hue account' > 'Hue account' and follow onscreen instructions. Log into your My hue account and you’re good to go. Please know that you will need to be connected to your home network when setting up out-of-home functionality for the first time. Also be advised that you need to have a 3G/4G connection to control your lights when you are not within reach of your Wi-Fi network.
