id8 Group R2 Studios was started in 2011 by Silicon Valley entrepreneur and investor Blake Krikorian. It recently launched a Google Android application to allow users to control home heating and lighting systems from smartphones.
Krikorian's Sling Media which was sold to EchoStar Communications in 2007 made the "Slingbox" for watching TV on computers.
Krikorian will join Microsoft with a small team, according to the Wall Street Journal, which reported the acquisition earlier on Wednesday. Microsoft also purchased some patents owned by the start-up related to controlling electronic devices, the newspaper added.
Krikorian and a Microsoft spokesman declined to comment.
Krikorian resigned from Amazon.com Inc's board in late December after about a year and a half as a director at the company, the Internet's largest retailer.
