When SwitchBot Color Bulb is attached to a socket, the socket is the power supply side.
If you've had a power cut in the socket, it's the same as Color Bulb suffering a cutoff.
At this time, if you switch on the socket again, the state of the Color Bulb will be changed depending on the "Power Loss Recovery" setting.
Power Loss Recovery is the setting of the state of the Color Bulb after being recovered from a power cut or a sudden power outage.
1."Keep previous state"- It is the default setting.
So if the state of Color Bulb before the power cut was OFF, it would be kept in the OFF state when power turned on. If the state of Color Bulb before the power cut was displaying a color, it would show the same color when power turned on.
2."On" - Color Bulb would show the same color you set last time.
3."OFF"- Color Bulb will be turned off.
If you have any problems, please set the Power Loss Recovery as follows.
