Technologies directed to detecting and controlling different types of ZigBee devices on different ZigBee networks reliably and efficiently. In one method of operating a first device, the method includes detecting first and second Zigbee networks. The method sends a first request to rejoin the first Zigbee network, the first request being encoded with the first network key. While rejoined as part of the first Zigbee network, the method detects a first set of devices part of the first Zigbee network. The method repeats this for a second set of devices part of the second Zigbee network. The method determines, using the device data, a subset of controllable devices located in proximity, and sends a message with the command to each in response to receiving a command. Each message is encoded with a respective network key and a respective link key specified in the device data.

Detecting and controlling different types of Zigbee devices on different networks and channels

Technologies for a wearable device are described. One wearable device includes a radio and a processor, the processor measures sensor data (e.g., a first angle between the wearable device and a first wireless endpoint device and a second angle between the wearable device and a second wireless endpoint device) and motion data indicative of motion of the wearable device over a first duration of time. The wearable device also measure signal strength values for communications with the respective devices. The wearable device predicts, using a first trained model, a position of the wearable device and to which target device the wearable device is directed. The wearable device predicts, using a second trained mode, a gesture made by the wearable device. The wearable device sends a message, corresponding to the gesture, to the target device to control the target device.
