How to Choose the Right DIY Home Automation System
First of all, let me preface this by saying there is no right or wrong way to set up a DIY home automation system. However, chances are there is a system that’s right for you. My goal here is show you several of the options available. With that information and your own understanding of your needs, you can make the best choice.
Why You Need a Smart Home Hub
Before getting too excited about any one suggestion I make, I would recommend that you take a moment and think about how tech savvy you are, and the amount of time and/or frustration you want to give to this project. You could waste a lot of money if you go down the wrong path.
At the core of your system you’ll need a hub. A hub can be a piece of hardware or it can be a software platform that you’d run from your computer or phone/tablet. All your components—things like smart locks, light switches and more—will branch off from the hub, and communicate with it.
Which brings us to compatibility. There are several unique languages or protocols these devices communicate with. You need a common language through all your devices. Examples are Z-Wave, ZigBee, WiFi and more.
Bear in mind, in most cases, who manufactures a device is often irrelevant. As long as any two devices share the same protocol, they should communicate with each other.
Home Automation System Hubs (Smart Home Hub)
Amazon Echo-Plus w/ Built in Hub
I know you’ve heard of Alexa, Amazon’s voice assistant. The integrated hub allows you to start building your smart home/home automation system with simplicity. This is a ZigBee hub, and will allow you to add an array of devices which you can control with your voice. Once you’ve installed your devices, say, “Alexa, discover my devices, and you’re done.” You can’t get much easier than that.
The Echo-Plus retails for US$199.99.
Samsung calls this hub “the brain of your smart home.” Unlike the Echo Hub, this one communicates using Z-Wave. If you want to control your home with voice, you can use any of the Echo or Google Home devices. If voice isn’t your thing—yet—you can also download an app for your phone.
As far as connected devices go, there is a wide range of compatibility, and Samsung provides an exhaustive list of compatible items on their website. Note these aren’t necessarily Samsung manufactured devices. The Smart Things hub communicates with devices that have the right protocol, in this case Z-Wave, and a number of other technical requirements.
For example, Ecobee4 smart thermostat are Samsung SmartThings compatible. Philips Hue Lights also are compatible as well. However, you need the Hue Bridge to make sure Philips Hue Lights work well with Samsung SmartThings – Keep reading to see the reasons below.
The new Wink Hub offers something the above mentioned hubs don’t, and it could be a game changer. Keeping in mind the fact other hubs only communicate using one specific protocol or language, the 2nd generation Wink has broader capabilities. It will support Bluetooth LE, ZigBee, Z-Wave and several other protocols, meaning it can control far more devices. This hub is designed with you in mind, the average consumer. Setup is easy, as it will auto discover all your devices.
The Wink Hub 2 retails for US$99.00.
The above mentioned hubs are simple to use and simple to set up. Perfect for someone just beginning to dabble in home automation who isn’t a tech geek.

Home Assistant and a Raspberry Pi
If you think I’m talking about dessert, you should probably just skip this section. If you know what I’m talking about, proceed.
Home Assistant is an open source program that will run on most operating systems. Think of it as a control center that allows you to track and automate all your devices. Using something called Hass.io, Home Assistant can be run on a Raspberry Pi instead of a computer OS.
Home Assistant is not for the faint of heart. It has a huge learning curve, but once you figure it out, it’s a significantly more robust way of automating your home than any of the above mentioned options.
Home Assistant can be downloaded for free.
Now that you understand the foundation of a home automation system, what sort of devices can you add to it? Well, the sky is pretty much the limit.
Whether you’re thinking about outdoor or indoor home security, there are several smart cameras you can choose from. There are the Ring and Nest Hello Doorbells and a variety of Netgear cameras. However, I need to point out that for these, and any of the following devices, you’ll need to check on which hubs they’re compatible with. If you’re going the Home Assistant route, it’s pretty much compatible with everything.

Most of the bigger manufacturers of traditional door locks now have smart locks. Schlage and Yale locks are two that are worth looking into. The August Smart Lock is another favorite. It locks as you leave and unlocks when you arrive. Imagine not having to struggle with a key when your hands are full of groceries or a sleeping child.
Interior/Exterior Lighting
Let Hue Lights color your world. These lights will require a Hue Bridge. The lights communicate with the Bridge and the Bridge communicates with your hub. You have a huge selection of options with Hue and can set up a variety of scenes. Your lights can be controlled either by voice—assuming you have some sort of voice assistant component in your system—or with an app on your phone.
However, as I mentioned above, 2 devices can communicate with each other, if they speak the same protocol. Using the Samsung SmartThings or Echo Plus as a Zigbee hub meant that once the bulbs were screwed in, they could be discovered and added within the SmartThings app or Alexa app. No need for the Hue Bridge.
But wait a minute!!! Are the any problems or risk when you try to do that?
Unique Functionality.
The Hue Bridge provides a lot of additional functionality you may want to take advantage of (such as the native scenes, groups, schedules, rules, etc.) that you cannot get without it.
Not Using the Bridge Can Mess Up Your Zigbee Network.
The most important is that adding Hue bulbs directly to your SmartThings hub will cause the bulbs to be identified as repeaters for your other Zigbee devices. It means you have possibility of lost messages from these devices.
Moreover, there is literally no way to reset your Hue bulbs if you decide you want to move them to a bridge later or even another SmartThings hub.
Support From Phillips and Samsung.
If you do have above problems, Phillips and Samsung are not going to help you because both they said, the official integration between Hue and SmartThings requires that the bulbs be connected to the Hue bridge, not directly to the SmartThings hub.
The safest and easiest way is just to buy a starter kit with the bridge from Hue Philips. Follow the directions to add the bulbs to the bridge, then follow the directions to add a bridge to your SmartThings account and you will be all set.
Smart thermostats can take home comfort to a whole new level. They can also help conserve energy and ultimately save you money. By using room sensors, you also have the ability to adjust temperatures room by room. Simply place the sensors about the home, and then tell the system where to prioritize your heating or cooling.
Hopefully, some of this info will help you in making a decision when it comes time to set up your home automation system. The market is full of choices, and more are being added all the time. How much money you have to spend, how much time you want to spend, and the depth of your tech knowledge should all be given some consideration before you make your choice. Also, in line with the fact that more devices are being added all the time, it’s a good idea to start with a system you can build upon.
