ZigBee and Thread act to make their IoT smarts stack up

Two pieces in the complicated puzzle of smart-home options will snap together later this year when the ZigBee Alliance starts certifying devices that use the Thread protocol for networking.
The industry groups behind these two systems have agreed to work out how they can both be integrated into the same product: Thread for exchanging data packets with other devices and ZigBee for defining how applications work on the device. This should lead to ZigBee products that can talk to many more devices
