A mixed mesh networking system includes Wi-Fi devices, ZigBee end devices, and a mixed network communications device including a Wi-Fi transceiver and PCB, a ZigBee transceiver and PCB, and an antenna connector. The mixed network communications device communicates with another mixed network communication device via the Wi-Fi transceiver and PCB and the antenna connector, communicates with the plurality of ZigBee end devices via the ZigBee transceiver and PCB and the antenna connector, self-configures as an Internet access point after finding a path to the Internet or scan the another mixed network communication device via WiFi to find the Internet access point, and self-configures as a ZigBee coordinator or a ZigBee gateway after identifying the plurality of ZigBee end devices that are connected to the mixed network communications device via ZigBee communication. The mixed network communications device may be a separate device relative to the plurality of ZigBee end devices.
