Kwikset - Signature Series SmartCode 916
Best Buy says "coming soon" for this using ZigBee.
1) When will it be available?
2) Will it definitely be ZigBee or ZWave?
Our system is Zigbee and we have 2 units. Be sure to search specially for the Zigbee model. The units we have actually work with both Zigbee and Z-Wave. It's a simple switch on the unit to change.
