The first ZigBee online store was announced last week by Vesternet. Except of Vesternet’s core products: Zigbox – a compact ZigBee Ethernet gateway and Zigbytes – a web-based user interface, you can find there a log of ZigBee devices produced by different vendors. Does this means that interoperability of third part ZigBee devices is solved? Most probably yes. Will see. In any case open of Vesternet’s online store is a good opportunity for smarthome enthusiasts and professionals to try ZigBee. EU and worldwide shipping is also good addition!
P.S. Unfortunately, ZigBee still has interpolation problems. So, compare it with Z-Wave the last one is more preferable technology for wireless automation.
