Q1:Why my bulbs are blinking?
The bulb starts blinking indicating that it is in pairing mode and ready for installation. Turn on/off via manual switch may result in a flash. Once connected to the wifi, forget the manual switch, and control the light by App and Voice.
Q2:Why my smart bulbs buzzing?
Smart bulbs need full voltage to be supplied to them. Buzzing is often caused by the less voltage, for example
-Using dimmers to change the brightness
-Turn on the larger appliance(microwaves)
-Home voltage changes.
Additionally, LED bulbs are known to generate a little“buzz”, but the noise level should not be noticeable from a distance of over 3 feet by FCC regulations.
