After a holiday season that saw HomeKit outed as insecure while Amazon’s Echo and Google’s Home smart speakers grabbed more headlines, CES this year is hosting a number of Apple HomeKit smart home accessories with an unexpected new feature: support for Amazon’s Alexa and Google Assistant.

One example: smart door locks. In October 2015, Schlage debuted its Sense Smart Deadbolt as an Apple HomeKit accessory. This year, the company came to CES with a different message — Sense gained support for Alexa ahead of the holidays, and will add Google Assistant integration in early Q1 2018. Another smart lock, Array from Brinks, will launch (after extended engineering delays) with Amazon Alexa support first, adding HomeKit and Assistant support later.

Lutron is another example. This established smart home accessory maker was one of the first to ship HomeKit accessories in June 2015, and even developed an Apple Watch app. At CES this year, however, Lutron has focused on touting its support for Amazon’s Echo, the Amazon Alexa-integrated Sonos One, and its “alliance with Nest” to integrate its Caséta Wireless system’s controls with Nest’s cameras and security products.
