Samsung Electronics is a founding member of the HCA along with Arçelik, The Electrolux Group, Haier, GE Appliances and Trane Technologies. The alliance brings together leading manufacturers of connected devices to enhance the compatibility of smart appliances across brands. As part of the alliance, Samsung will work with other member companies to develop shared guidelines for cloud-to-cloud interoperability, accounting for data security and consumer safety requirements. For Samsung users, this means the ability to operate and control appliances from other brands through its smart home platform SmartThings, making it simpler for consumers to integrate legacy and new devices into their connected homes. Alternatively, consumers will be able to access Samsung devices from other HCA member applications.
