Here's what's available now. Lutron's Caséta Wireless Smart Bridge will let you control lights, shades and other devices in specific rooms by barking commands at Siri, using your Watch, or via an iPhone or iPad. You can also remotely control devices when you're away from home, or set up geofencing so that the lights flick on when you enter a room. The Wireless Lighting Starter Kit is available today for $230, and you can add remote dimmer kits for $60.
Insteon is offering a bit broader solution with a full-on smart home hub that can control its current family of products (pricing is yet to come). Those include cameras, alarms, smart bulbs and other products working across WiFi and RF home standards.
As for products coming soon, Elgato, is bringing Eve sensors (above) that detect temperature, humidity, energy use, motion and even air quality. If you're looking for a smart thermostat, Ecobee will cover you with its $249 Ecobee3 model that's coming in July (below). It'll regulate temperature on its own or give you room-by-room control with satellite sensors. Finally, iHome revealed a $40 HomeKit-compatible SmartPlug you'll be able to pre-order on June 15th, giving you control over lamps, fans and other gadgets.
It's a modest start, considering how long it's been since Apple first revealed HomeKit. And new as the products are, it remains to be seen if everything will work as smoothly as promised -- naturally, we're as keen to try them out as you are. Hopefully, we'll hear more news soon (and possibly see more products), as it's rumored that Apple will be revealing more HomeKit information during its WWDC developer's conference next week.
