Samsung Electronics has launched an in-house service that could link a variety of devices and home appliances.

The South Korean electronics company will showcase its latest Smart Home service at the opening of the Consumer Electronics Show (CES) in Las Vegas on Tuesday.

The Smart Home service can link numerous devices, utility controls and home appliances – given that those are all Samsung products.

When going out, for instance, the owner can say “going out” into a smartwatch app and that will prompt lights and the television to shut.

Samsung affirms that though the service would only support selected Samsung merchandises, including Galaxy Gear smartwatch and Samsung televisions, consumers can expect the service to cover other brands’ devices and appliances eventually.

The company added that aside from household gadgets, it also plans to expand its services to support door locks, medical devices, and some “eco-home applications,” and release a software protocol to assist other manufacturers on how to link up their gadgets.

However, Martin Garner, an analyst who is covering connected homes technologies at CCS Insight, is uncertain that competitors will support Samsung’s plans.

 “Samsung is the most aggressive competitor that exists. So, why would another manufacturer want to use its platform?” Garner told BBC News.

“Samsung have had the same connected home vision for a while, but their implementation of it was a bit ragged,” he added.

Samsung has attempted to develop different apps for the Smart Home service before but it didn't fare well. Thus the need to delay the launch of the service. However, that issue has been resolved.

Another issue that Samsung needs to look at, based on Garner's observation, is the "branding loyalty" of the customers. This one needs serious work as most customers tend to purchase only a single Samsung appliance instead of buying a complete set.
