The Wi-Fi Alliance and ZigBee Alliance got together this week in a public demonstration of interoperability between Wi-Fi devices and ZigBee-enabled smart energy meters at DistribuTECH in San Antonio. They were promoting the new Smart Energy Profile 2.0, designed for energy meters.
The multi-vendor demonstration established Wi-Fi device connectivity to both Wi-Fi and ZigBee meters, reports Fierce Wireless. It was reportedly the first time that this kind of mixed technology has been publicly demonstrated.
Products to be certified with the Smart Energy Profile are expected to include thermostats, appliances, electric meters, gateways, electric vehicles, and countless other devices in the Smart Grid. Eight vendors: Aclara, Broadcom, Elbrys Networks, Gainspan, Grid2Home, Intwine Energy Networks, Qualcomm Atheros and Texas Instruments demonstrated interoperability.
Texas Instruments announced 2.4 GHz Zigbee radio, with an integrated ARM Cortex-M3 processor, Smart Energy 2.0 hardware security acceleration, enabling simplified, cost-effective, smart grid connectivity for electricity, gas or water smart meters and in-home displays.
ZigBee is a low-cost, low-power, wireless mesh network standard. It runs on the 915 MHz and 2.4 GHz band, but is cheaper and slower than Bluetooth with a defined rate of 250 kbps. It’s used for intermittent data from sensors or input devices.
The Wi-Fi Alliance said it is now working to develop a certification program for SEP 2.0 products. Interoperability with WiFi will allow appliances to “talk” to to each other and connect to the internet.
