Yeelight LED Bulb (Color)
#1

Hello.
I bought Meteoite LED ceiling lampplus.
But there are two problems.

  1. The installation is good and the lights come in, but the Bluetooth settings are not fixed.
    If the wall switch is turned off for initialization, the light will not turn on after 2 seconds.
    (No lights immediately, light after 5 minutes)
    The remote control is good.

  2. After an hour of turning on the light, it turns off, turns on, and changes automatically.
    Then, after a certain period of time, it turns dark.

Please help me solve the problem.
