Smart lighting systems consist of light sources, control units, communication protocols, and cloud platforms. How do they achieve remote control, scene linkage, and energy consumption management through IoT protocols? What are the basic algorithms for color temperature and brightness adjustment? What do you know or have experienced regarding these core principles? Feel free to discuss.

I recently set up a small smart lighting system using ESP8266 + MQTT, where the control unit adjusts brightness via PWM and smoothly transitions color temperature using the Hue-Saturation-Value algorithm. I also integrated it with Home Assistant on my phone to enable remote switching and energy consumption tracking through scene automation. During testing, I noticed that the latency in cloud platform state synchronization significantly affects real-time scene transitions, so I recommend caching the state locally before reporting it.
