Yes, to protect the sockets and sensor.
Wyze Plug Outdoor should plug directly into an outlet and then hang down so that water does not run into the sockets. It should not be left flat or in standing or running water.
If you would like to use the light sensor, it needs to face away from the wall so the sensor is exposed to the surrounding environment and can detect ambient light.
Important: Wyze Plug Outdoor should be plugged directly into your power outlet. We do not recommend connecting the outdoor plug to an extension cord as this could result in damage to your Wyze device and void your device's warranty.
