Pros of WiFi vs Z-Wave\/ZigBee\/BLE<\/span><\/h2>

OK, so you don\u2019t want to go with a wired connection.\u00a0 Let\u2019s take a look at how WiFi compares to the other common home automation protocols.<\/span><\/p><\/div>

Price<\/span><\/h3>

WiFi-enabled smart devices are usually less expensive compared to their counterparts. It is also much easier to find DIY devices that use WiFi, making it a cheaper option.<\/span><\/p><\/div>

WiFi Is More Common<\/span><\/h3>

WiFi is already a necessity and is in most households. It\u2019s easier to purchase devices that are already WiFi-enabled. For people who are new to home automation, the protocols like Z-Wave and ZigBee might be totally new and sound too technical. Plus, they require a new hub.<\/span><\/p><\/div>

Simplicity - No Need for Extra Hardware<\/span><\/h3>

WiFi takes the lead when it comes to simplicity - that is, when you don\u2019t need to connect dozens of devices and only a minimal number of devices for a home automation set-up. Since it is very common, you don\u2019t need to invest on extra hardware when you only need the basic setup for your home automation system.<\/span><\/p><\/div>

Cons of WiFi vs Z-Wave\/ZigBee\/BLE<\/span><\/h2>

WiFi Isn\u2019t Designed to Create Mesh Networks<\/span><\/h3>

Mesh networking is a fancy term used to refer to devices that are able to talk to one another. The network allows multiple paths to a destination device. A mesh network increases network reliability in home automation, boosts signal as they hop to the next device, and prevents loss of signal. Imagine this scenario - if one of your devices is turned off in a signal path, the network will simply find an alternative route to its destination device.<\/span><\/p>\n

<\/p>\n

Newer routers like the Orbi can form a mesh network between routers, but that\u2019s not nearly as good as a network between each devices.<\/span><\/p>\n

<\/p>\n

Z-Wave and ZigBee are common wireless device protocols that communicate via a mesh network by default. Unlike Z-Wave and ZigBee.\u00a0 The makes for a stronger network over longer distances.<\/span><\/p><\/div>

High Power Usage<\/span><\/h3>

WiFi consumes 10 times more energy compared to similar devices using ZigBee, Z-Wave, or Bluetooth Low Energy (BLE). Your WiFi devices will drain your battery faster and eventually become more expensive in the long run. On the other hand, ZigBee, Z-Wave and BLE are designed for low-power devices. This is the reason why you can hardly find a battery-operated sensor or device that uses WiFi - most of these devices use Z-Wave, ZigBee or Bluetooth.<\/span><\/p><\/div>

A Limited Number of Devices Can Be Connected<\/span><\/h3>

Many WiFi routers can only allow up to 30 devices connected at once. If you are using lots of devices like smart bulbs or smart switches, you will eventually run up against the limited device count. On the other hand, Z-Wave allows 231 connected devices per network while ZigBee can handle thousands!<\/span><\/p><\/div>

Pros of WiFi vs. Ethernet\n<\/span><\/h2>

Convenience<\/span><\/h3>

Home automation requires the connection of multiple devices such as cameras, lights and switches, monitors, sensors, and many others. The wireless nature of WiFi allow you to connect and access multiple devices easily. Plus, most of us already have WiFi in our homes.<\/span><\/p><\/div>

Expandability<\/span><\/h3>

When setting up your home automation system, you may decide someday to add more devices on your system. This would mean adding new cables if you have a wired network. The benefit of using a WiFi network is that you can simply add new devices without the hassle of additional wiring.<\/span><\/p><\/div>

Lower Cost<\/span><\/h3>

Compared to its wired counterparts, WiFi offers bigger savings in cost and labor associated with running physical wires or cables. For home automation devices like smart plugs and outlets, WiFi chips are very cheap due to their pervasive use in computing and mobile devices.<\/span><\/p><\/div>

No Unsightly Cords\/ Cables<\/span><\/h3>

Devices connected to WiFi only require a single access point. You can easily setup your devices anywhere you want without unsightly cords and cables. On the other hand, wired systems will require complex planning to run physical cables to numerous locations, especially in areas that are far away from the main router and outlets. <\/span><\/p><\/div>

Connect Multiple Devices Wirelessly<\/span><\/h3>

Using a WiFi network means you have more free router ports. You don\u2019t need an additional Ethernet outputs - simply connect new devices on the network. Most good routers will support hundreds of connections.<\/span><\/p><\/div>

Cons of WiFi vs. Ethernet<\/span><\/h2>

Limited Distance to Cover<\/span><\/h3>

The WiFi network with standard equipment can be limited in range through walls and other obstructions in a standard home, but it\u2019s usually sufficient for a typical house. But if you have a larger home with many rooms and you want to put sensors and monitors in every corner, then a typical WiFi network may not be enough. You may need to add repeaters to reach longer distances or use a mesh network.<\/span><\/p><\/div>

The Number of Devices that Can Be Connected is Limited\n<\/span><\/h3>

While it\u2019s true that you can connect multiple devices on the network wirelessly, the number of devices can be limited, some wireless routers only allow up to 32 devices. Moreover, as you connect more devices, the channel becomes saturated and may affect overall performance of your system, sharing limited bandwidth across scores of devices.<\/span><\/p><\/div>

Interference<\/span><\/h3>

WiFi is just like any radio frequency transmission - it is subject to interference and complex propagation effects that are beyond the control of your network provider. Interference can affect\u00a0 the performance of your WiFi signal and slow down your network. Some common sources of interference include microwave ovens, other wireless peripherals, fluorescent lights, Bluetooth devices, and cordless phones.<\/span><\/p><\/div>

Obstacles<\/span><\/h3>

Whether we like it or not, obstacles can block your WiFi signal and affect the devices connected to it. The main reason is that WiFi uses shorter radio waves which cannot just penetrate any obstacles between your devices and router. The more obstacles, the more difficult it is to have a good signal. Common obstacles at home include metal, walls, glass, fluorescent lamps, and electronic devices that use radio frequencies to transmit data. Even the ground can be an obstacle if you\u2019re in a basement.<\/span><\/p><\/div>

Connection Speed<\/span><\/h3>
The fastest speed of WiFi is much slower than a wired network, and that\u2019s just with one device with a dedicated connection. This may not be very significant if you only have a few devices connected to your network. But as you add more devices<\/a>, you may eventually experience slower speeds and higher latencies, affecting your overall home automation system as well.<\/span><\/div>

Security and Privacy Issues<\/span><\/h3>
Internet security is a hot topic riddled with lots of \u201crabbit holes.\u201d Although there are various encryption technologies you can use, most of these methods are quite common and have their own weaknesses that can be easily exploited by hackers. Plus, a WiFi signal can be easily jammed using a smartphone or wireless landline phone. For example, if your home security system depends on WiFi, intruders can block the signal easily and disable your alarm system<\/span>. Hackers can also access live footage of your home through your WiFi cameras and exploit any information they can get to break into your home or get your personal details. You can read about Vivint camera hack and check how hackers can mess up with your WiFi cameras!<\/span><\/div>

What You Can Do<\/span><\/h2>

Using WiFi to enable your home automation system is not totally doom and gloom -\u00a0 you just need to implement ways to improve and protect your network. Here are our short tips you can do at home:<\/span><\/p><\/div>

Get the Best of Both Worlds<\/span><\/h3>
WiFi, ZigBee, Z-Wave and BLE have their own pros and cons, depending on how you use these devices as well as your goals for your setup. For example, Bluetooth is designed for short distance only so you may not find it suitable for two devices that are installed far away from each other. Plus, you can connect directly from your phone!\u00a0 ZigBee and Z-Wave can use mesh networks to increase reliability and increase battery life, both lacking in WiFi. Many home automation hubs will allow you to use devices with multiple types. See our <\/span>Samsung SmartThings<\/span><\/a> review to see one of them.<\/span><\/div>

Use Only What You Need<\/span><\/h3>

Planning ahead before you invest in a home automation system is important to avoid needless costs. If you are just starting a home automation system, we recommend you begin with the basics such as smart lighting and eventually add devices as needed. Make sure that you don\u2019t add devices that you don\u2019t really need or whose functionalities are already present in your existing devices.<\/span><\/p>\n

<\/p>\n

An added benefit is that you won\u2019t annoy the rest of your family with home automations that are finicky and cause problems when you focus on doing a few things really well to get started an sell them on your dream too. ;)<\/span><\/p><\/div>

Check Your Settings<\/span><\/h3>

When setting up your devices, make sure that you check its settings as well as the app settings to ensure that you are only giving enough information for your devices to function. Never forget to check these settings whenever your devices are updated.<\/span><\/p><\/div>

Use Different Devices that Use A Common Language<\/span><\/h3>

When investing for a home automation system, you don\u2019t have to put all your eggs in one basket. Rather than put your entire home under one company, a mix of devices is safer plus you get to experience features that other companies may not offer (as long as these devices don\u2019t have compatibility issues).<\/span><\/p><\/div>

Use Repeaters If Needed<\/span><\/h3>

WiFi can be easily affected with obstacles and interference. You can add repeaters as needed to improve its performance, especially if you have a large house with many rooms where you want to deploy your devices. <\/span><\/p><\/div>

Secure Your Network<\/span><\/h3>

Smart homes require us to be smarter and more vigilant. Despite the advances in technology, internet security is still a hot issue that can put your home at risk if not being cared for. You can implement methods or tools to secure your network and keep any outsiders from connecting and taking over your network. Some of the simple things you can do are changing your router password, changing your network\u2019s SSID name, filtering MAC addresses and only adding those that are from your devices, and enable network encryption.<\/span><\/p><\/div>

Wrapping it up<\/span><\/h2>

Smart homes are growing and soon most homes will become connected online. WiFi offers lots of advantages including convenience, mobility, and wireless transmission. However, it also comes with disadvantages that include speed performance, security and privacy issues, and limited distance. On the other hand, other home automation protocols like Z-Wave, ZigBee, and BLE also offer features that you may not find in WiFi-enabled devices. At the end of the day, it\u2019s all about interoperability - each of these protocols have their own advantages which you can use for your home automation setup.\u00a0<\/span><\/p>\n
