To set up your C by GE devices to turn on when your Wire-Free Motion Sensor detects motion, you will need to group the Wire-Free Motion Sensor and those C by GE devices into the same Room in the C by GE app.
Example below shows the C by GE app room titled "Entryway." This app room includes the Wire-Free Motion Sensor, one C by GE plug and two C by GE light bulbs. The Wire-Free Motion Sensor will trigger those three C by GE devices when it senses motion. Be sure to adjust your "Room Motion Sensor" settings so your C by GE devices are controlled the way you want them to be controlled by the Motion Sensor.
