How Zigbee Pro Makes Life Easier for IoT Developers

Uncategorized, , , , , , , , ,

The IoT has proliferated our everyday lives in a growing variety of ways. In 2021, there were more than 10 billion active IoT devices. That number is expected to grow past 25.4 billion by 2030. IoT solutions will generate $4-11 trillion in economic value by 2025.

Hundreds of manufacturers create IoT devices of all varieties—interoperability is necessity. In order to facilitate this, IoT developers generally adhere to a communications protocol known as Zigbee Pro.

WHAT IS ZIGBEE PRO?

 

Zigbee Pro is a low power, low data rate Wireless Personal Area Network (WPAN) protocol which streamlines device connections. The goal of the protocol is to deliver a single communications standard that simplifies the nauseating array of proprietary APIs and wireless technologies used by IoT manufacturers.

Zigbee Pro is the latest in a line of protocols. The certification process is facilitated by the Zigbee Alliance—now commonly known as the Connectivity Standards Alliance—which formed in 2002. The Connectivity Standards developed the first version of Zigbee in 2004 and gradually rolled out improved versions until the most current version in 2014.

HOW DOES IT WORK?

Zigbee is composed of a number of layers that form a protocol stack. Each layer contributes functionality to the ones below it, making it easier for developers to deploy these functions without explicitly having to write them. The layers include a radio communication layer based on the IEEE standard 802.15.4, a network layer (Zigbee Pro), the application layer known as Dotdot, and the certification layer which is compliant with the Connectivity Standards Alliance.

One of the focuses of the Zigbee standard is to deliver low-power requirements. Battery powered devices must have a 2 year battery life in order to be certified.

ZIGBEE DEVICES

Mesh networking enables Zigbee networks to operate more consistently than WiFi and Bluetooth. Each device on the network becomes a repeater, which ensures that losing one device won’t affect the other devices in the mesh.

There are three classes of Zigbee devices:

Zigbee Coordinator – The coordinator forms the root of the network tree, storing information about the network and functioning as a repository for security keys. This is generally the hub, bridge, or smart home controller—such as the app from which you control your smart home.

Zigbee Router – The router can run application functions as well as act as an intermediate router to pass data on to other devices. The router is generally a typical IoT device, such as a powered lightbulb.

Zigbee End Device – This is the simplest type of device—requiring the least power and memory to perform the most basic functions. It cannot relay data and its simplicity enables it to be asleep the majority of the time. An example of an end device would be a smart switch or a sensor that only sends a notification when a specific event occurs.

The Zigbee Pro protocol has become the gold standard for IoT developers. Many commercial IoT apps and smart home controllers function under the Zigbee Pro protocol. Examples include: Samsung SmartThings Hub, Amazon Echo, and the Philips Hue Bridge.

Apple Brings the Internet of Things Home with HomeKit & iOS 10

Anyone engrossed in the tech scene knows the Internet of Things is one of the trendiest technology topics on the web. The IoT is shaping our world and building fortunes for innovators, futurists and top app development companies. However, in the common household, the IoT has yet to break through to the mainstream. The biggest company in the world is now looking to enact change.

Tim Cook, in his September Announcement, declared that iOS 10’s HomeKit update is the first time home automation has been integrated with a major platform. While Apple introduced HomeKit in 2014 with iOS 8, iOS 10 comes with a dedicated app called Home that controls all home automation devices.

HOME IS A HOME RUN

Home combines IoT technology with the masterful UI of iOS. Previous iterations of iOS and HomeKit required the user to manage each interface separately. So if a phone had 20 HomeKit apps, they would have 20 user interfaces to manage. The Home app unifies HomeKit apps, creating a central control center for all home automation applications.

With over 1 billion active Apple devices across the world, Home enters the market with giant global reach. Virtually every major manufacturer of home automation devices now supports HomeKit. Accessories cross all major categories, from lights and air conditioners to window shades, locks and home security. Commercial IoT companies now have massive domestic reach, and iOS users have more incentive to update their homes than ever before.

HAVE SIRI SET THE SCENE

One of the coolest features of Home is the Siri integration. Users can control Home from both the Control Center and Siri, but Siri can work at the speed of your language. Siri’s ability to handle multiple requests means users can accomplish their ideal environmental preferences in the speed of a sentence. Apple refers to these combination commands as “scenes” and users can give “scenes” a nickname. A rambunctious user might say “Hey Siri, let’s get funky,” prompting Siri to lock the doors, dim the lights, put Barry White on the speakers at a reasonable volume and provide the most apt customized ambience for the user to rock out.

THE APPLE TV IS THE HEARTH

The fourth generation Apple TV can also act as a hub for the Home app, with the Siri Remote making it easy to control your home on the go. Apple TV’s seamless integration with HomeKit and other iOS products makes it the ultimate smart TV for a smart home, providing yet another reason for consumers to consistently buy iOS products.

BUILDING COMMERCIAL IOT FROM THE GROUND UP

The Home Automation page on the Apple website is a clear indicator of Apple’s intentions to not only be a household name, but to be the name on your household. The company already has a major market share of phones, tablets, computers, TVs and watches. They are rumored to be looking to acquire McLaren as a part of Project Titan. Apple understands that the ubiquity of the iOS platform makes them the most appealing platform for manufacturers of smart devices. Apple also announced that leading home builders, including Brookfield Residential, KB Home, Lennar Homes and R&F Properties, are integrating many HomeKit devices into new homes.

With the Apple Home potentially on the horizon, one can only wonder how much of Apple’s vision of the smarthome will be realized in the next 5-10 years.
