We’re now in the age of Smart Home Automation – powered by the Internet of Things – and what a time to be alive. As new smart technology continues to emerge, we’re seeing the way we go about our daily lives change before our very eyes. You can change the mood of a room with a simple voice command that cues ambient lighting, romantic music, and even turns the cameras off if it’s that type of mood. And even if you’re totally single, you can arrive home to vacuumed floors and freshly cooked rice, thanks to your beloved smart home appliances.

Perhaps one of the best things about the rise of smart home automation is that it’s actually pretty affordable, making it more accessible to the average person! If you’re looking to build a truly smart and connected home, this guide is just for you. We take a look at some of the best categories to begin when venturing into the world of smart home automation. But first, let’s meet the smart assistants.

Decide on a Smart Assistant

If you’re serious about building a smart and connected home, deciding on a smart assistant is the best place to start. They offer a convenient way for you to interact with various smart devices without juggling multiple apps. Most smart devices are compatible with multiple assistants, but on the off chance it isn’t, it always pays to check.

If you have a smartphone, it’s likely you already have a smart assistant, and you might want to stick with the same one. If you’re on Android, you’ll have a Google Assistant or even Alexa built-in. If you’re an iPhone user, you’ll have Siri. Alternatively, you might want to choose a separate smart assistant for your home that’s based on compatibility or intelligence.

For those wanting to build an Apple-based ecosystem, keep in mind that there aren’t as many devices that are Apple HomeKit compatible. If you want a fully integrated smart home with various devices, then Google or Alexa might be the best choice for now.

Smart Hubs

Smart Hubs are the centralised component of a truly smart and connected home. They act as the ‘master controller’ for your smart devices, making it easy for them all to work together. A smart hub lets you connect multiple smart devices – that otherwise might not be compatible – and have them perform coordinated routines with each other. For example, when you leave the house, a Smart Hub can tell your lights to turn off, your locks to shut, and your surveillance cameras to start running. Or when your scheduled smart lights turn on in the morning, the Smart Hub can tell the kettle to start boiling.

If you’re on team Alexa, there’s the Amazon Echo Smart Hub; the Apple HomeKit for those sticking with the Apple eco-system; and the Google Nest Hub for Google Assistant. There are also third-party Smart Hubs that are compatible with multiple voice assistants. The most readily available Smart Hub in NZ at the moment is the Google Nest Hub (2nd Generation), which does more than keeping your smart devices connected. With a 7” HD display, you can watch YouTube videos and your favourite Netflix shows on it. And if kept by your bedside, it has additional smart features of its own, such as Sleep Sensing which can track when you go to bed, when you wake up, and how long you’ve slept.

Choose a router that’s fit for the job

Your router has the important task of connecting all of your smart home devices, so you want to make sure you have one that’s fit for the job. Unfortunately, routers provided by ISP providers generally won’t cut it, and if this is the case for you, shopping for a new router should be a top priority if you want a seamless smart home experience.

When shopping for a router for your smart home, there are three minimum requirements to keep an eye out for:

  • 802.11ac Wave 2 (or better) – This wireless standard enables MU-MIMO which allows your router to communicate with multiple devices simultaneously. Resultingly, the wait time for a signal to each device decreases and the speed of your network increases.
  • Dual-Band Radio (or better) – This gives you the ability to connect to two different networks (either 2.4GHz or 5.0GHz), which allows for faster speeds and flexibility. Some routers even offer Tri-Band Radio which may be worth considering if you’ll have a lot of users on your network.
  • 1200MBps Speed (or better) – This represents the speed of the 2.4GHz band and the 5.0GHz band combined. Ultimately, the speeds you experience will depend on your internet plan, the number of users, and your home environment, but a minimum speed rating of 1200MBps is good to shoot for to have minimal to no interruptions.

Optional: Mesh Wi-Fi for large homes or dead spots

If you have a large home or experience ‘dead spots’ in certain areas, you should consider a Mesh Wi-Fi router. A Mesh Wi-Fi system adds satellites around your home to broaden the coverage of your Wi-Fi, blanketing your home in smooth, reliable Wi-Fi. The more satellites you add, the stronger and better your Wi-Fi becomes.

Optional: Wi-Fi 6 to future proof your smart home

Wi-Fi 6 is the future of Wi-Fi. It’s a more recent version of 802.11ac, known as 802.11ax, that offers faster connections, improved performance, lower latencies, and wider network coverage. At the time of this article, devices that support Wi-Fi 6 are limited, but you can expect support to broaden over the coming years. While Wi-Fi 6 isn’t necessary for a smart home, purchasing a Wi-Fi 6 router now will future proof your smart home for faster speeds and improved performance down the line.

Smart Lighting

Smart lighting is the first place a lot of people start. It’s really just as simple as changing a light bulb, and the satisfaction goes well beyond that. Most smart bulbs work perfectly well without a central hub and can be controlled via apps. The exact features available depend on the Smart Bulb, but they generally give you the ability to schedule your lights, or manually turn them on and off from your phone; dim the lights; adjust the colour temperature; and if you’ve got an RGB Smart Bulb, you can even change the colour and make them strobe. If you want the benefit of controlling your lights with a simple voice command, you’ll definitely want to pair it with a Smart Assistant. What makes smart lights even better, is they can lower your electricity bill. All smart lights are LEDs, which consume far less electricity than incandescent and even fluorescent bulbs.

Smart Speakers & Audio

The ability to control your smart home devices with a simple voice command makes them even better, and that’s where smart speakers come in. You merely have to speak commands to your gadgets for them to do your bidding. Turning off the lights becomes as simple as saying, “Turn off the lights”. There’s more to them than that though. Smart speakers can also tell you the news and weather, answer questions, provide traffic updates, play music, or even order an Uber.

There are plenty of Smart Speakers on the market, with leading audio brands even jumping in to include smart assistants on their speakers. The first step to choosing a smart speaker is considering which Smart Assistant you decided on, and researching your options based on that. The most popular smart speakers include the Amazon Echo and Google Nest range of products. If having the best sound is your top priority, you might want to consider Bose speakers which are compatible with both Google and Alexa.

Smart video doorbells let you take a peek at what’s happening on your doorstep without opening the door. When the doorbell is pressed or the built-in motion sensor is triggered, you’ll receive a notification directly to your phone, tablet, or laptop. With video and audio streaming directly to your device, you can let visitors know you’ll be down in a minute; tell delivery drivers where to leave a package; avoid pushy salespeople, or catch package thieves and other pesky criminals in the act. Some video doorbells such as those by RING, even have a built-in siren which you can sound to chase unwanted visitors away. Smart video doorbells are a great addition to the smart home, and add a layer of security to your front door.

Smart Door Locks

Smart locks are one of the best entry points into a smart, connected, and secure home – literally. Let’s be honest - keys are somewhat outdated. They can easily be picked by anyone who is well-practiced, and they can easily be lost too. Not to mention the convenience and benefits they’re lacking in comparison to the modern smart lock, such as providing easy access to multiple people; notifications when the door is unlocked or locked; the ability to manage and restrict access from your phone; and peace of mind. PB Tech sells three popular brands of Smart Locks: Lockly, Yale, and Schlage. Different smart locks will not only have different features, but also different requirements, so you’ll want to keep that in mind when shopping too.

Smart Cameras & Surveillance

Smart security cameras give you peace of mind, allowing you to keep an eye on your house from your phone, tablet, or laptop. They often have additional features that can help catch criminals in the act or deter crimes from happening in the first place. For example, you can receive notifications directly to your phone if motion is detected, and speak to intruders via a built-in microphone. If connected to a smart hub, you can set motion sensors to trigger your smart lights to turn on, creating the illusion that someone is home; or they can also trigger floodlights or other smart security devices to go off.

Unlike traditional security cameras, which save data to a PC and require cables running all over your home, smart security cameras are often wireless, connect to your Wi-Fi, and upload data securely to the cloud. This means they’re often much easier to set up, and can be much cheaper. Whether you’re looking for indoor surveillance, outdoor surveillance, or even just baby and pet monitors, there are plenty of smart options on the market to choose from.

Smart Security

If you want home security that goes beyond camera surveillance, there are many more smart security devices to consider. We’ve been over smart video doorbells and smart locks, but we’ve yet to talk about motion sensors, floodlights, and alarms. Systems like Eufy’s Security 5-Piece Home Alarm Kit add an extra layer of protection to your home with a motion sensor, door and window sensors, home alarm system, and more! You’ll be notified via your smartphone, as soon as any motion or a breach is detected; at which point, you can choose to sound the alarm. If connected to a smart hub, you can automate the process and have total peace of mind knowing you’ve got all bases covered!

You don’t need to purchase an entire security kit though, and you have the option to shop for motion sensors, and alarms separately. If you want to up your security further, you might want to add floodlights to your set up too.

Smart home appliances are all about streamlining certain tasks and making life easier. We’re talking vacuumed floors and freshly cooked rice before you’ve even walked in the door from a long hard day at work. Appliances like the Xiaomi Robot Vacuums can be scheduled to clean at set times, without you even being there. Likewise, you can schedule the Xiaomi Electric Rice Cooker to start cooking rice from the Mi Home app or your smart hub.

Further to those, you can add a Smart Thermostat that adjusts the temperature or humidity based on the environment or a schedule; you can add a Chromecast to your TV to make it a Smart TV, and you can keep track of your weight with a Smart Bathroom Scale that syncs your health stats with your phone and other smart fitness devices.

If there’s not a smart option available, smart plugs allow you to turn any regular appliance into a smart one! Of course, the smart perks you get will be limited, but for some devices, that little bit extra is all you need. Connect your appliances (or other electronic devices) to power via a smart plug, and you can schedule them to turn on and off at certain times, sync with other smart home devices via your Smart Hub, or you can manually switch them off from your phone (ideal for situations like when you can’t remember if you’ve turned your hair straightener off or not).

Now that you’ve dipped your toes into smart home automation, there’s probably no going back. Once you’ve experienced the perks and convenience of one smart device, you’ll just want more! Head over to PB Tech to check out our entire range of Smart Home products today.
