Yee Light

Go library to control YEELIGHT devices for dinosaurs with scary faces

Disclaimer

• Library is not in stable state and not finished (few missing features)
• User interface may be slightly changed before 1.0 release
• Device auto-discovery are not implemented yet, You'll need to connect to them directly with IP address.
• Tested only on one type of bulb (Yeelight Smart LED Bulb (Color)), I can't guarantee that everything will work correctly on other devices

Usage

make sure LAN control is enabled in your device:

Device initialization:

yl.NewBulb("192.168.0.123")
