On December 29, 2015, Honeywell completed the acquisition of Elster for US$5.1B (announced on July 28, 2015) entering the space of gas, electricity, and water meters with a specific focus on smart meters and hoped to be a growth driver for Honeywell in 2016 and beyond. The deal also complements the HON Combustion business with the addition of Elster with strong brands such as Kromschroeder and Eclipse. Honeywell International Inc. then acquired the 30% stake in UOP Russell LLC it didn't own already for roughly $240 million in January 2016. In February, Honeywell entered into a definitive agreement to acquire Xtralis, a leading global provider of aspirating smoke detection along with advanced perimeter security technologies and video analytics software, for $480 million from funds advised by Pacific Equity Partners and Blum Capital Partners. The deal was completed on April 1, 2016. In May 2016, Honeywell International Inc. settled its patent dispute regarding Google subsidiary Nest Labs, whose thermostats Honeywell claimed infringed on several of its patents. Google parent Alphabet Inc. and Honeywell said they reached a "patent cross-license" agreement that "fully resolves" the long-standing dispute. Honeywell sued Nest Labs in 2012. In 2017, Honeywell opened a new software center in Atlanta, Georgia.
