The Smart Home Has Finally Come of Age


Almost 15 years ago I attempted to convert our house into a smart home. Back then many smart devices were controlled using the X-10 protocol, which communicated over power lines. It was cool when it worked, but it was far from reliable. Fortunately the connected home has come a long way since then. Here’s why I believe the smart home is now ready for prime time:

Why Smart Devices Have Come of Age

  • Voice-activated – Smart controllers like Amazon’s Echo control thermostats, light bulbs and smart hubs using your voice. Voice-activated controllers are easy to use because they respond to natural language commands like “Alexa, turn off the family room light.”
  • Better reliability – Many smart devices are now controlled using ZigBee or Z-Wave. These newer smart home protocols have many advantages over the earlier home automation protocols like X-10. First, they don’t communicate over power lines, so they are much more reliable. Products like light switches and outlets act as signal repeaters, so they extend the range of your network. Second, they communicate over a mesh network, so any smart device can talk to any other smart device. Finally, some of these new protocols don’t use the same frequencies as Wi-Fi products, so they are much less susceptible to wireless interference.
  • Interoperability – Smart hubs like Samsung’s Smart Things work with Wi-Fi, ZigBee, Z-Wave and cloud-connected products like Amazon’s Echo. In fact, over 1,000 different products work with SmartThings today, so you won’t hard a hard time finding compatible products. Although SmartThings is a Samsung product, it works with iPhone as well. In the future, the SmartThings hub is supposed to work with the Thread home automation protocol, which Google and others are using, as well as Bluetooth, which Apple’s HomeKit uses.


  • Easy to install – The first smart home devices were connected using wires. Now, many devices are wireless. To add a motion sensor, you just stick it to the wall using adhesive tape. If you decide to move it later, you can do so without leaving any holes in your wall. These smart devices are battery-powered, so they don’t need an AC adapter, or connection to wall power. They even report their battery level to the smart hub, so you’ll know when it is time to purchase a new battery. In case you are wondering, batteries last about a year.
  • No security keypads or loud alarms – Today’s smart home can be programmed to automatically arm itself after every family member has left. Only then will you be notified when there is motion. There’s no need for a loud alarm that annoy your neighbors. You’ll receive a text that tells you what triggered the alarm (e.g. smoke, fire, motion or a water leak). If you have cameras installed, you’ll see what caused the motion. When the first family member returns home, the alarm will be automatically turned off, without the need to enter a long security code. And the best part is, you get all of these services and more without a monthly fee.
  • Mass appeal – Smart home products are no longer just for nerds. Nest thermostats, Dropcam and Amazon’s Echo are all extremely popular. Over 100,000 Nest thermostats are sold every month. Over 3 million Amazon Echos have been sold to date. These companies have also done a good job explaining how these devices work with other smart home devices, so they have effectively primed the pump for other smart home products. Once Apple’s HomeKit catches on, and Google comes out with their smart hub, millions of additional consumers are likely to create their own smart homes.
  • Smart devices do more – Samsung’s multi-sensor can detect contact open and closed status, movement, vibration, and orientation (vertical or horizontal). Smart outlets measure energy usage and act as signal repeaters. Some smart thermostats also detect motion, so they can automatically turn off your air conditioning when you are away. Some wireless smart devices also report temperature, so they could detect a fire in an area of your home that does not have a smoke detector.
  • Better software and services – The first smart hubs only worked with software from a single company. Today’s smart hubs and controllers work with apps, plug-ins and services from a wide range of different developers. Apps are available that do a wide range of things. If you can’t find an app that does what you want, you can create your own, or modify existing apps. The best part is that you do not have to an experienced programmer to do this. Amazon Echo users can use a wide range of plug-ins called Skills and services including Pandora, Spotify, iHeartRadio TuneIn, Audible, Amazon Music and Prime Music.


Things a Smart Home Can Do for You

There is almost no limit what is possible in today’s smart home. Here are just a few examples of the things you can do:

  • Have your air conditioner automatically turn up it’s thermostat so it doesn’t run after all of cars used by your family have left your neighborhood
  • Setup your Sonos to play the sound of a loud dog barking when there is motion and you’re not home
  • Have your Jawbone to automatically open your window blinds and disable your alarm when you get up in the morning
  • Recieve a text after your mail has arrived
  • Use your phone to start a “Good morning” mode that adjusts thermostat, turns on a coffee maker and starts your favorite music playlist, or a “Goodbye” mode, that opens your garage door, turns up the thermostat, turn off all of your lights and locks your doors
  • Get a notification on your BMW dashboard if there is an intruder, fire or water leak in your home
  • Use a sensor to monitor the moisture in your soil and only turn on sprinklers when needed
  • Use your iPhone or Android smartphone to control any smart device in your home. Have you ever left your home and realized that you forget to turn something off? You can now address issues like this using your phone – no matter where you are.
  • Make a voice call on an Ooma Telo using an Amazon Echo
  • Turn on a ceiling fan after the temperature rises above 78 degrees
  • Change the color of your lighting based on different events. For example:
    • If there’s a water leak, turn my lights blue
    • If there’s a smoke alarm, turn my lights red
    • If there’s a fire, turn on all of the lights in my home
  • Record 10 seconds of video prior to the start of an event, so you can see what triggered an alarm. For example, if someone were to kick in your front door, you’d see the door fly open and the face of the person as they entered, not just the back of their head

And last, but not least, a smart home will save you money. Nest Labs released a white paper last year, which showed a smart thermostat saves its owner 10-12% on heating and a 15% on cooling. That’s a savings of up to $145 a year. ecobee claims an average savings of 23%. If you live in Southern California you can get two $150 ecobee thermostats for free if you agree to raise your thermostat on peak usage days. You’ll save even more if you have your lights automatically turn off when you exit a room. I could go on, but you get the idea. If you can dream it, you can probably do it.

How to Get Started

Start by buying a smart hub. The hub is the brain of your smart home, connecting you and your devices via apps on your phone, tablet or computer. Once you select a hub, you can start buying smart devices. I started with an Amazon Echo. Then I bought a smart hub and two motion controllers for $180. Discount coupons and sales are common. There are also money-saving bundles available that include a smart hub, motion sensor, two multipurpose sensors (that monitor whether doors, windows, or your garage are open or closed) and an outlet to control lights, or small appliances. Here are some tips how to make your smart home more reliable:

  • Locate your hub wisely – It’s tempting to put your smart hub next to your Wi-Fi router, but that’s not the best place for it. Locate it in a central location that is not too close to your router and other wireless devices.
  • Watch for interference – Because ZigBee devices share the same 2.4 GHz band as Wi-Fi products, they could have problems with interference. When possible, have your smartphone, laptop and media streamers to use the 5 GHz band to eliminate wireless interference. If you must use the 2.4 GHz band, use a mobile app like this one to change to a less congested Wi-Fi channel. Sonos products can also interfere with ZigBee devices. Z-Wave devices are more reliable because they use a less congested wireless band.
  • Create a device map – It’s a good idea to draw a simple map of your connected home and the estimate the distance of each device from the smart hub or the closest device with the same protocol.


    • Pay attention to the distance between your smart hub and ZigBee devices, because their maximum range is 35 feet. Every time ZigBee or Z-Wave signals go through a wall, their range drops. Z-Wave has a maximum range of 100 feet however, if you have metal junction boxes and dense walls, the range can drop to only 17 feet. Try to arrange devices and repeaters to have line-of-sight communication with each other, or at most one wall (or floor) between them.
    • Color code Z-Wave and ZigBee devices differently on your map, because ZigBee devices can only communicate with other ZigBee devices and Z-Wave devices can only communicate with other Z-Wave devices.
    • Circle all devices that act as repeaters. Keep in mind that battery-powered devices cannot act as repeaters.
    • Techie tip: Rotating your smart hub can solve signal problems. Try to determine which direction your antennas radiate and position the hub so it doesn’t radiate away from your devices.
  • Use repeaters to extend your range – Z-Wave and ZigBee device utilize mesh networking, which allows signals to “hop” through other devices to reach the destination device. However, both have range restrictions (as discussed above). Add a repeater if some of your smart devices don’t respond reliably. Keep in mind that a ZigBee repeater won’t extend the range of a Z-Wave device.
  • Tune-up your network – As you add smart devices, the topology of your network changes. There are several things you can do to improve the communication between your smart devices and hub:

    • Z-Wave devices do not automatically look for new “parents.” Once a device picks a parent, it will hold on to it until it cannot talk to it any more, even if a different parent is added to the network that would be a better choice. To make sure your Z-Wave devices are routing optimally, look for a “Repair Z-Wave Network” command in the software for your hub.
    • You can force a ZigBee device to pair with a better parent by turning off your hub, and leaving it off for up to 10 minutes so the device loses communication with its former parent (the hub). After you turn back on the power to your hub, your ZigBee devices will find better parents (if they exist).

The Last Word

The smart home has come a long way. The best smart home hubs support multiple connected home protocols so you can choose from a wide range of devices. Interoperability between products is good and there is a wide range of products available including motion sensors, presence sensors, moisture sensors, door locks, electrical outlets, voice activated controllers, smoke detectors, smart light bulbs, garage door openers, vents, sprinklers, blinds, speakers, thermostats and much more. Smart devices communicate over a mesh network, which improves as you add more devices and connected to the cloud so you can monitor and control your smart home anywhere in the world. It’s time for you to think about automating your home. Start simple and add products over time. There are many good videos online that will help you get started. Have fun!

How to use less than 100MB of mobile data each month

I recently switched carriers from Verizon to Google’s Project Fi. Google only charges you for the data you use, so it is in your best interest to use as little as possible. I used to use 3GB or 4GB of data each month. Now I use less than 100MB of data every month. You read that right. I reduced my data usage by 40x. Read on to learn how to do it and still use your phone every time you need it.

  1. 1Turn off cellular data when you don’t need it– Some apps use cellular data when Wi-Fi is available. Almost all apps use data in the background when you are not using them. I found that I had apps that I never used that wasted large amounts of data. Over an entire month, this really adds up and eats into your monthly data plan. Even with cellular data off, you’ll still be able to make calls and send or receive texts over the cellular network.
  2. Monitor your data usage and uninstall problem apps– It’s essential that you go to Settings and review your cellular data usage. Be aware which apps use the most amount of mobile data. Social media, news and weather apps are notorious for syncing often – even if you rarely use them. If you uninstall Facebook, Snapchat and popular news and weather apps, you’ll be surprised how much data and battery life you save. You can still access Facebook using your mobile browser whenever you want to. News and weather sites can be accessed via browser as well. You can even bookmark them so they appear on your home screen like an app. Try to only use apps like Instagram and web browsers over Wi-Fi, because they use lots of data.
  1. Restrict background data usage– It’s highly recommended that you go to Settings > Data usage and view the app background data for your apps. I’ve enabled ‘Restrict app background data’ on all apps and haven’t had any problems. When you do this, a warning will appear, but you can ignore it. I’ve been doing this for almost a year without any problems whatsoever. I was surprised to find that apps I never use consumed a lot of background data. There is a global setting to restrict background data, but I recommend you do this on a per app basis, so you can enable any apps that have a problem in the future.


  1. Only update apps on Wi-Fi – Make sure you go to Settings in the Play Store app and go to ‘Auto-update apps’ and set it to ‘Do no auto-update apps’ or to ‘Auto-update apps over Wi-Fi only.’ This will save you large amounts of data.
  1. Avoid streaming over mobile – Streaming audio or video uses much more data than text. Download your favorite songs and playlists so you can listen to them offline. Avoid streaming video from sites like YouTube or Netflix over mobile because this can consume extremely large amounts of data. Consider switching to a carrier like T-Mobile with their binge-onplan, which lets you stream endless amounts of music or video without eating into your data plan.
  1. Never use maps with cellular enabled – Google Maps consumes huge amounts of data when you use it for driving directions. Most people don’t know that you can use turn-by-turn driving directions without using any mobile data if you load your directions while you are connected to Wi-Fi. If it ever says “Lost data connection” turn on cellular data for a few seconds and it will fix the problem. Then turn it back off. You can do this with the quick settings menu, so it doesn’t distract you from driving. Better yet, do this when you are waiting for a stop light to change. You can also cache maps before you leave or select a region on a map and have it work offline, but I find that to be unnecessary.
  1. Use Wi-Fi whenever it’s available– Almost everyone has Wi-Fi access at home and work so the only time you should turn on mobile data is when you are on-the-go and out of range of Wi-Fi. Free public hotspots are common and there are apps that will help you find them. Most broadband providers provide access to free Wi-Fi hotspots as well. Another tip is to go to your favorite sites before you leave home in the morning. I sync my email, news app, Twitter and RSS feed apps before I leave the house. This saves me over 100MB a day.


  1. Change your sync settings – You might want to try disabling ‘Auto-sync data’ by going to Settings > Accounts > Google and touching the 3 dots in the upper right. When you are connected to Wi-Fi, you can manually sync all of your Google accounts at any time by going to Settings > Accounts > Google and touching the 3 dots in the upper right and selecting ‘Sync now.’ You can also reduce data consumption by adjusting your Inbox to check for mail less often. I have mine set to ‘Never’ and I still receive notifications when new mail comes in. This change is made in the mail app and not on the Settings pages.
  1. Know your daily data budget – If you want to consume less than 1GB of data a month, you need to keep your average data usage under 33MB a day. If you consume 60MB in a single day, don’t worry. It won’t be a problem as long as consume less than 32MB on a few other days. I try to use an average of 3.33MB a day, so I stay under 100MB. It’s not hard to do because I often go days without using any mobile data. If you suspect an app is using too much data, download software like App Tune-up Kitand use it to select the app you want to test. It will run for one minute and measure the amount of mobile data used by the app. [Disclosure: I was on the team that created this app.] Most popular games use large amounts of mobile data. You should only play these apps when you are connected to Wi-Fi.
  1. Avoid apps with ads – Apps with ads consume more mobile data than apps without ads. If the apps you use have ad-free versions available, purchase them. Spending a few bucks will save you money in the long run.

  1. Use other people’s data – If you have a friend or family member with unlimited data, ask if you can tether and share their data. If you’re phone doesn’t support this feature free of charge, there are apps in Google Play like FoxFi that do this very well. Make sure they work with your phone and carrier before buying them. They generally have a trail version.

Using mobile data consumes over twice as much power as Wi-Fi data, so following the above steps won’t just save money, you’ll also extend your battery life. I ended up reducing my monthly phone bill from over $70 to about $23 a month. That’s a savings of around 60%.  Check to see if your carrier offers discounts if you change your plan to one that uses less data. If they don’t consider switching to a carrier who does. The savings add up quickly. In five years, I’ll save $2400.

You don’t have to follow all of the above steps to save data. Even if you only try a few of these suggestions, you could cut your mobile data usage in half. The more steps you follow, the more you’ll save.
