HomeOS is the working title of a home automation operating system that was being developed at Microsoft Research in the early 2010s. Microsoft Research announced the project in 2010. HomeOS communicates with Lab of Things, a cloud-based Internet of Things infrastructure also developed by Microsoft. The slogan for the HomeOS project is "Enabling smarter homes for everyone." Some staff who worked on the HomeOS project cited Microsoft CEO Steve Ballmer's focus on enterprise applications, productivity software, and cloud computing as the reason for the stalled development of HomeOS.
