A new enrollee device is configured for a communication network using an electronic device and a network registrar. The new enrollee device is a headless device that lacks a first user interface for configuring the new enrollee device for the communication network. The electronic device obtains, at a sensor, sensor information that is indicative of a device key associated with the new enrollee device. The electronic device determines the device key based on the sensor information. The device key is provided to the network registrar to cause the network registrar to configure the new enrollee device for the communication network.
