Let's ignore three wireless communication technologies that are unsuitable to the majority of IoT applications: Infrared (IR), cellular connectivity, and Near Field Communications (NFC). What are the best existing technologies for enabling this wireless communication? How can developers of IoT devices and apps design products to be user-friendly? As wireless communication technologies have not quite caught up to the needs in IoT, the answer, unfortunately, is that it's complicated. As these devices become smarter and generate an ever increasing amount of data, the need to be controlled by or communicate with a mobile device presents some difficulties to developers. One thing these products have in common is that they communicate wirelessly with either a mobile device, the Internet, or both. Not only are there a variety of different whites -from “Daylight” to “Night light” - but Philips offers a handful of preset color stories: “Candlelight,” for instance, which filters through different shades of yellow, or “Ocean,” which filters through different shades of blue.Internet-of-Things (IoT) devices are increasing in popularity and availability - think Amazon Alexa, smart thermostats & light bulbs, Internet-connected garage door openers, GoPro cameras, and so on. The Philips Wiz Smart Bulbs let you light up your room in a bunch of different colors - millions, according to Philips. The Wiz Bulbs don’t cost very much either, making them a good first step into the world of smart lighting. The app makes it easy to change each light bulb’s colors - or turn them off completely - straight from my phone. They connect to my smartphone via Wi-Fi and they’re individually customizable via the Wiz smartphone app.

The Philips Wiz Bulbs I bought make this possible. Where once I relied on my phone’s flashlight to lead me to sleep in the evening, for example, I now rely on my phone to tell my smart bulbs to dim and eventually turn off. The significance of light in my apartment has grown steadily over the years.
