Samsung, which already makes a variety of home appliances, just acquired a company that can help them work better together. Smart Things was founded to cut through the confusing network of standards that currently exist among home-automation products, and sells a $99 hub that lets appliances communicate across standards. Samsungs current appliances have some ability to communicate with each other, but the company said SmartThings would enable them to expand the reach and capabilities of home automation.
