When Internet of Things devices debut at this year's CES, one of the biggest questions will be how they'll connect to all the other smart-home gear on display. But anyone who expects a clear answer to that is like a kid who gets up Thanksgiving morning looking for a bunch of gifts under a tree.
The fact is, it's too early to say what standard or protocol will become the glue that can turn a pile of cool gadgets into a system that runs your whole house for you. New systems are just starting to emerge, and though they may eventually work with each other and with older platforms, buying one of each and expecting harmony is still wishful thinking.
Connected homes may make life easier eventually. A thermostat linked to a garage-door opener could tell who's coming home and set the heat or air-conditioning for their preferences. Compatible room lights and an audio system could join in, too.
That vision's starting to catch on. Ownership of connected home devices in the U.S. grew by 50 percent this year, and fully 43 percent of all households in the country will buy one in the next year, research company Parks Associates said last month.
For now, most people only have their eye on one device, said NextMarket analyst Michael Wolf. They may buy a connected thermostat for its features, or buy a networked garage-door opener because their old one broke, but they're not after a whole-home setup yet.
For those who are, there are already ways to tie devices together without giving up a weekend. Many vendors offer hubs to make their own home products work together, and some have opened these systems up to others. Samsung has SmartThings, Belkin has WeMo, retail chains like Lowe's and Staples have their own platforms, and smart-home specialist Insteon has a line of hubs and devices, to name just a few.
Broadband providers like AT&T and Comcast also offer selected products and ensure they work together. These systems may start with home security and expand to include things like lighting and climate control.
But having a vendor or carrier decide which products can understand each other won't be enough in the long run. Some new platforms are designed to offer a broader selection of products that consumers can add on easily.
That's where new buzzwords like AllJoyn, OIC, Brillo, Weave, Thread and HomeKit come in. But there are two things to keep in mind.
