Recommend to buy, good stuff Has some pros: - Setting brightness, light temperature - Ability to save settings and return to them automatically after turning on, or set up a default scheme that will work when turned on - several different applications for working with the lamp (Mi Home, Yeelight + SmartThings built into the Samsung notification curtain) - there are nice candle, fireplace, birthday and party modes Cons below: It is impossible to set up without Wifi, for example, only via Bluetooth and the lamp does not have the ability to work autonomously without the Internet - it would be convenient, since we turn off Wi-Fi at night, without it, the dawn (alarm clock) mode will not work
