More SmartGrid consolidation

Sigma buys Z-Wave

Surprise. Surprise. There has been more consolidation in the smart grid segment, as Sigma Designs is seeking to buy Zensys.

According to Greentech, "Zensys is the primary driver behind Z-Wave, a wireless, energy-efficient protocol that allows lights, appliances, security cameras, thermostats and other devices to talk to each other. Z-Wave is a single chip solution and is cheaper than competing technologies like ZigBee and WiFi, say advocates."
