Bringing joy with Sonos, Lutron, Kaleidescape and more: Some of the latest home-technology products to ring in a happier new year. Don't forget the power protection.

International Data Corporation report says smart speaker and other smart home devices sales will grow at quick clip over the next five years.

The reasonably priced Smart TV Series offers a choice of screen sizes ranging from 43 inches to 65 inches, and includes access to 'The Roku Channel.'

All the big 2018 news from TCL's New York reveal: 5/6 Series 4K TVs with Roku, Dolby Vision, HD, low prices from $349; plans for Onkyo brand acquired from Gibson; and major investments in artificial intelligence (AI) for audio, video and control.

Futuresource research shows 4K TVs, set-top boxes and streamers from Roku, Apple, Amazon are widely accessible, but 4K content is sparse, and HDR suffers from lack of standards.

Kaleidescape reclaims the top position, followed by Autonomic, Sonos, Apple and Roku. Falling out of the top five brands are TiVo and Crestron.
