Arrayment works with manufacturers of connected products, such as Whirlpool, Chamberlain, Maytag, and Pentair.
Not to be outdone, Zigbee Alliance is there with a booth showing off many of their partners. Word, though, from talking to folks is that Z-wave better integrates many different brand products, their standards are, I guess, tighter. Both certainly allow you to control their respective devices. But, it would seem, that if you want a lot of different companies tech to be controlled by other companies software, apps, etc, at this point, Z-Wave seems to have the edge in that regard!
Another player, Centralite, offers a full selection of light switches, outlets, dimmers, motion sensors, etc. Lots of product lines are showing some products, now, but their charts show building out more and more related products, smart lights, etc.
I will also note, though, that one of the things apparent at the show is that we're starting to see WiFi being used specifically in devices and, even more importantly, in a low-power consumption BlueTooth. So some of the products we've got pictures of here may be using those kinds of things as well. Similarly, Bluetooth appears as a controller format. Even the Energizer bunny is in on the act with a wireless surge protector/rapid charger that uses blutooth to keep you informed, and to control - stay in touch with USB and other devices, and they featured wireless charger pads, among other devices. A company I wasn't familiar with - BeeWi, showed a whole wall full of products using Blutooth. We hope to include a number of bluetooth enabled devices in our Dream Home project. Stay tuned! Speaking of "smart," I found The Big Bright Light at Cisco. This is important because it looks like they're OEMing these lights from Philips--that's probably good if you've got stock with Philips. But again, it's another group getting into selling colored lighting, and that gives me an alternative source for getting more lights to integrate into our Smarter Home Project. And I do believe that lighting and color will be the future of home decor. Speaking of Cisco: You know "The Internet of Everything" is their line. Here's an image of their monitoring system showing the cost of operation of many smart devices in the home:
