hue Switch NFC is a simple Android app designed for changing the state of Philips hue lights using NFC tags. The app offers various options for controlling the lights, including switching off, toggling on/off based on current state, switching on, and setting colors stored on the tags. It supports group settings as well, although contradictory configurations may result in unpredictable state changes.

Users should note that storing current color settings for groups can be complex due to the way group states are managed. The app requires the hue bridge to be initially connected to the internet for discovery purposes, but once the IP is obtained, internet connectivity is no longer necessary.

To read data from NFC tags, users simply need to place the tag when the app is in the foreground, enabling convenient control of Philips hue lights via NFC technology.
