I recently developed a c# YeelightAPI (.Net) to control my Yeelight Bulbs.
It is open-source on GITHUB, and it's also available on NUGET
It's still in development and everything is not yet implemented, so pull requests are welcome
My plans are :
1. Implementing network device discovery
2. Add more basic methods (like cron, scenes etc.)
3. Group devices
4. Any ideas ?
Hope that could help someone !
