Yes, and you have two options:
Use the light switch.
You can turn the Wyze Bulb Color on/off with a light switch.
Note: Wyze Bulb Color will return to the color, temperature and brightness settings that it was set to before being turned off with a light switch. If there is a total loss of power due to an outage or other reasons, Wyze Bulb Color will turn on regardless of the previous state.
Use a voice command:
Control Wyze Bulb Color with a voice command through Alexa, Google Assistant, or an automation applet in IFTTT.
