I cannot log in to my Hue account via the Philips Hue app, what can I do?
Check if you are logged in to your Hue account in the Philips Hue app. Go to ‘Settings’ and check if you are logged in.
If not, login with your user name and password.
If it is not working, check the settings in your Hue account (https://account.meethue.com) if your Hue bridge is connected. Be sure that your Hue bridge is powered.
