From Wi-Fi-enabled thermostats to Bluetooth-accessible door locks to Z-Wave-connected alarm sensors to Zigbee-networked lightbulbs, there could be an array or wireless signals criss-crossing your house.
Why do we need so many different technologies that essentially do the same thing?

Likewise, the various wireless networks that make up a smart home each have their own use.
And just as those networks are invisible in the real world, solutions like Logitech’s Harmony Home Hub, which can talk to a database of more than 270,000 connected devices, are trying to make them invisible to smart home owners by controlling all these separately-networked smart home products — everything from connected coffee makers to smart window shades — through one interface. But until you get a home hub solution like the Harmony, it’s worth knowing why smart home product designers choose the networks that they do:
