Philips Hue isn't your only option for Echo-compatible lighting -- there's also Lifx, which makes color-changing LED bulbs with Wi-Fi smarts. Unlike Philips, the Lifx integration's color controls are already up and running -- that means you can tell Alexa to change to color of the bulb.
Belkin also makes an automatable WeMo Light Switch. If you're comfy with an installation that's a bit more hands-on, it's an easy way to smarten up a light fixture in your home. With Echo on board, you can let Alexa call the shots.

One of Alexa's newest integrations is with the Automatic connected car gadget, which plugs into your vehicle's onboard diagnostic port. Sync it up with Amazon Echo, and you'll be able to ask Alexa how much gas you've got in your tank, or even where you parked your car last.
Amazon Echo also has its own channel on IFTTT, a free online automation service. That makes it possible to craft automation "recipes" where Echo triggers other IFTTT-compatible smart gadgets and Web services.
Orange Chef is another name that Amazon is investing in. The product is a smart countertop that senses in ingredients and weighs your food as you're cooking. With Alexa on board, you'll be able to ask her about the nutritional content of whatever it is you're making.
Moving forward, Amazon hope that a growing number of third parties will jump in under Alexa's umbrella. Scout Home Security is one that's already in the mix -- Amazon is investing in the system as part of its $100 million Alexa fund, and basic Echo controls for arming and disarming your security system are already available.
