Amazon's Echo speaker and 4K Fire TV just got much better at handling around-the-house tasks. The Fire TV now controls smart home devices with a simple voice command -- you can ask it to dim the lights right before you start a movie. It'll search for local businesses and restaurants, too, in case you want to get some sushi when you're done watching. The Echo already has these features, but you can now ask it when a TV show starts to make sure you catch that big season premiere. Both the Echo and Fire TV upgrades are relatively straightforward, but they'll mean a lot if you're tired of bringing out your phone to ask simple questions.
