Internet of Things (IoT): An Introduction and Why You Should Care

The Internet of Things (IoT) is a hot topic right now, and not just because of internet-connected Nest thermostats. For the average person, though, IoT may not seem relevant. A “smart home” might sound like science fiction, but it’s something everyone needs to get up to speed on. Once you understand it a bit more, you can make a decision whether or not to embrace it.

A Working Definition of IoT

Much like “the cloud,” the definition of IoT varies by context and application. Here is the way I like to define it:

“Non-traditional networked devices that interact with the physical world in some way”

I admit that is a broad definition and could include almost anything. The phrase “non-traditional” focuses on things that aren’t typically networked. Your laptop, your printer, and smartphone are traditional devices. An electrical outlet, a lamp, and a doorbell are not. As IoT becomes more popular, that phrase “non-traditional” may seem archaic. We have to start somewhere.

Typical Characteristics and Types of IoT Devices

Although not required, most IoT devices usually have some cloud service to manage the device from the web or mobile app. The point of a device being networked is so you can access it effortlessly from anywhere you have an internet connection. A networked device you can’t access remotely doesn’t have much value.

Most people think of automated devices when they think of IoT. That’s because of the smart home concept we’ve been predicting since the 1950s. This category includes things like connected lights, switches, thermostats, and other home appliances (including smart batteries). Other home-based IoT devices focus on security like intrusion detection alarms, water alarms, security locks and internet cameras. The first internet camera watched a coffee pot at the University of Cambridge (geek trivia). We had IoT before we had the term IoT.

The quantified-self health monitoring devices also fall into that IoT category. These include fitness trackers, connected scales, and sleep monitoring and enhancement devices. We had pedometers before, but until recently, they didn’t upload through your phone to the internet. Smartwatches and other wearable devices combine lots of IoT characteristics.

Beyond those typical devices, there is everything else. I’ll include here one of my favorite IoT gadgets, the Automatic car adapter. It interacts with my iPhone and tracks my car’s movements, gas mileage, and location. It sounds creepy, but it isn’t.

Technology Standards That Connect These Devices

You don’t see too many devices interacting through wired Ethernet these days. Wired connections are not very flexible after all. We have some cameras in our home that still use wired Ethernet. You do see other wireless standards borrowed from “traditional” computing devices like Bluetooth Low Energy and Wi-Fi. For example, most fitness trackers use Bluetooth to connect to your phone or computer.

Beyond those technologies, there is a slew of other standards including Z-Wave and ZigBee. Those are protocols that let the devices talk to one another over their own wireless mesh network. Unless you’re a home automation nerd, these protocols don’t have much meaning to how you actually use IoT device. One of the beauties of IoT is all this stuff is hidden from you. Companies make it so it just works (except of course when it doesn’t). Home automation and internet connected devices were around before IoT was popular. The difference now is the systems are much easier to work with.

Hubs, Systems, and Devices: How Wink and Echo Fit In

Once you have a bunch of things, you hope they all talk to each other and the Internet. The hodge-podge of IoT devices in your home is usually managed by a central hub. If you just have a few devices, you might manage them with individual apps. One app to control the thermostat, another for the lights, and yet another for the alarm. When you have a Wink home hub or an Amazon Echo, these interact with the individual devices and remove the hassle of having a bunch of management apps.

Until recently, if I wanted to change the temperature in the house, I’d have to open the Nest app. Now, my Wink hub can control the Nest. My Wink also talks to my Echo so I can give voice commands to change the temperature. That eliminates the argument of who is getting out of their warm bed to turn up the heat in the middle of the night. It also makes it easier to argue about the temperature of the house and change it without your partner knowing. Such are the problems of modern life.

Does IoT Make You Rich, Thin, and Fabulous?

Maybe. It certainly couldn’t hurt, so let’s review each of those.


Why spend twice or three times as much for an IoT thermostat when a standard programmable one would do? It’s about saving money in the long term. I haven’t quantified my savings over time comparing a Nest to a standard thermostat. Nest sends me reports, but I don’t trust them. My home patterns change as much as the weather and this day last year can’t compare to this year even if the temps are the same.

Before my IoT thermostat, I’d go through the hassle of programming it four times a year or so. That is when I’d remember. We’d have to configure it for heat in the winter and cooling in the summer. Then we’d have to schedule turning it off when we aren’t at home or during sleeping hours. No need to cool the house when nobody is home or we’re asleep.

Home insurance companies often give discounts for having IoT monitoring devices in the home. They realize the easier it is for you to watch and monitor stuff, the less likely they are to have a loss. Our basement is less likely to flood and we’re more likely to set the intrusion alarm if we can do it remotely.


A fitness tracker won’t make you thin just by wearing it. Nor does wearing running shoes make me run. A fitness monitor will make you aware. That awareness could help with your fitness goals. I covered this before, but it’s less about the accuracy and more about the accountability. I could wear a pedometer and manually record my steps each day and compare them over time. The app does that for me. More advanced trackers that monitor heart rate let me not just compare steps, but physical exertion.


When these devices start interacting with each other, they do make you fabulous. Without much effort, you focus on other things in your life. For example, I have to track my mileage for tax purposes. Before my Automatic, every trip I made I’d have to mark in a paper booklet. I’d then put that in a spreadsheet for my accountant each year. Now, my Automatic tracks my mileage. I then have an IFTTT script that copies that data to a Google spreadsheet and an Evernote notebook. All I do is mark the purpose of the trip. That’s about 10 minutes a day I’m saving.

I also suffer from the “Did I remember to?” syndrome, especially when going on a trip. Did I remember to program the bedroom light? Did I remember to turn off the space heater? You get the idea. I don’t have to remember to program a single light switch. I can do it all through my Wink app. Since my space heater plugs into an IoT-enabled switch, I can turn it off remotely. Internet cameras point to key points in the house so I can check if I forgot something. I can’t quantify it exactly, but I’d say this knowledge reduces stress by at least a thousand percent. If I start worrying on the plane, I open up my apps and take care of everything remotely.

It’s not all sunshine and rainbows with IoT. You can spend a ton of money and have a home where you can’t figure out how to turn on the lights. News about hacks and security breaches are real, so consider this information before jumping on the IoT bandwagon. We’ll cover that in later articles. My quality of life is much better living in a connected home with connected devices.

    First – Great article. I keep hearing about the “Smart” home and I honestly don’t know where to start. I’ve looked at Amazon

    And honestly, I just got more confused. I want to get going with plugging in smart lights and plugs however, I can’t figure out WHICH controller to buy. I’m worried I’m going to get stuck with the BETAMAX version of Home Automation and then need to re-outfit my home….

    So — WHICH standard is winning and a sure bet for the future @Dave? And what’s the best way to dip in my toe? Also, should I go with the cheap GE smart bulbs or stick with what it seems is the best — Philips hue?

      Give it time. is going to make an IOT standard. Have tech patent that allow you to tap your phone(provided it has NFC) to any device. The device sends exactly how it works and operates without you having to set anything up. With the hub it allow you to communicate through a number of ways and with or without Internet. All off one app. Early stages yet but it is gaining a lot of traction.

      I’ll cover that in the next article. However, for the sake of argument, even if you get a BetaMAX of IoT, that isn’t the end of the world. It will still work after all. I’ve written about my frustrations with my Nest, but it still works better than a standard thermostat. Stay turned.
