Samsung said Friday it had reached a deal to buy a US home automation startup SmartThings, as the South Korean electronics giant aims to expand beyond the increasingly saturated smartphone market. With Samsungs resources and support, SmartThings will be able to expand its platform and become available for even more partners and devices, Samsung said in a statement. SmartThings will continue to operate independently under its founder and CEO Alex Hawkinson and will become part of Samsungs Open Innovation Centre, the statement said. The centre is responsible for developing Samsungs new software and services.
