Confused in the using of smart bulb?

Forget the manual switch once pairing successfully.

Gosund Smart bulbs could work according to App and Voice Command. Clap the switch after well-connecting, that may cause the bulbs to blink and getting into pairing mode after turning on.

Skills for Smart bulb always keep good connection.

Several routers may be needed in building a really smart home system, especially for a big house and many smart devices. Enough routers will make a good connection and reduce dropping wifi for too crowded and far distance.

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.
