IoT (Internet of Things) is the undeniable new trend in the world. We are now seeing the approach of the IoT era coming very close. It is time for you to consider upgrading your house to a new level with all sets of new smart devices. Light bulbs, door locks, air conditioners, and everything else is now under control of your phone. To organize the smart devices and assist your smartphones in connecting to them, brands have designed a hub, or the center for controlling. In this article, we will talk about some smart home devices and select the best smart home devices you can buy online.

Best Smart Home Devices for Reviews

1. Kasa Smart Plug Outlet

The first product we would like to introduce in our selected list for the best smart home devices is the Kasa Smart Plug Outlet. The Kasa Outlet is the first thing you need to know of when you get your hands on the smart device systems. Kasa Outlet lets you control any devices you want in your home by simply connecting and disconnecting the power into them.

The Outlet works with 2.4GHz Wi-Fi, advertised to be independent on the hubs or smart centers. The only thing you need to do is read the instructions to set up your outlet in under 5 minutes. The outlet then will work as expected, where you can control the power from anywhere in the world via the app, and schedule the devices to be on or off at specific times. 

Finally, the outlet works with Amazon Alexa and Google Assistant, sadly not the Apple Siri. The device is certified to be safe from electricity overload and trusted by over 5 million people over the world.

  • 2.4GHz Wi-Fi compatibility

  • Easy instruction manual

  • Amazon Alexa and Google Assistant compatibility

  • 5 million users so far

2. Echo Show 5 by Amazon

The Amazon Echo Show 5 was introduced several years ago to act as an alternative to the Apple HomeKit and Google Home. While Apple HomeKit and Google Home are both struggling to get a stable amount of customers in the world of early IoT systems, Amazon Echo Show has been living so well under the protection of the Amazon ecosystem. 

Echo Show 5 acts like an information center for all your smart home devices. Echo Show shows weather information, air conditioner’s status including the temperature or the timers, your events from your smartphones, your light configurations, and everything else. As a member of the Amazon family, it is obviously determined to work completely with Alexa. Unfortunately, it doesn’t seem to function with your Google Assistant or Apple Siri.

The product features a 5.5-inch screen with the Fire platform acting in the background. It even has a front-facing camera to assist you when you want to video call with your friends in the kitchen. 

  • Amazon Echo system

  • Center for information

  • Alexa Assistant

  • Front-facing camera + Mic

3. August Wi-Fi 4th Gen Smart Lock

Designed with the motto of being simple, the August Wi-Fi 4th Generation Smart Lock is recommended by Apple to work with its smart ecosystem. August smart locks from outside look like a giant blocked cylinder you usually see in science fiction movies. 

As for the features, the August 4th generation is manufactured with the capability of working with 2.4GHz Wi-Fi networks in a 45% smaller case than the previous generation. With the Wi-Fi enabled, the lock can be controlled from anywhere using the August branded software. You can also use one key pair for multiple locks in the house, or share the keys with your family members or friends. Additionally, the fingerprints or faces make up an additional security layer for the locks.

The lock can be integrated into your existing locking system of your house, though it does require some screwdriving the deadbolt and door hardware. We have personally tested this lock and we found it easy to replace it with our existing traditional lock. Finally, the lock works with Alexa in the Amazon ecosystem, Siri in the Apple ecosystem, and Google Assistant in Google ecosystem. It takes no effort at all to check your status, when you feel paranoid about whether you have locked your door at home or not.

  • Apple recommended

  • Alexa, Siri, and Google Assistant compatible

  • Easy replacement with intuitive manual

  • 45% smaller than previous generation

  • 2.4GHz Wi-Fi required

4. Smart WiFi Light Bulb

The next product of our list today is a light bulb. This Smart WiFi Light Bulb is made by LUMIMAN for working with Alexa and Amazon smart home solutions. It follows the trend of smart home devices that don’t require a Hub to work. Instead, it uses the Wi-Fi 2.4GHz to transfer and receive data. The unfortunate thing about the device is that it only works with 2.4GHz Wi-Fi; therefore, if you don’t fancy the 2.4GHz, you would not get it working.

The light we introduce in the article today is multi-colored, which means you can select a specific color in a spectrum of yellow colors or green colors. It is also dimmable and adjustable for different light conditions.

  • 2.4GHz Wi-Fi

  • Adjustable and dimmable for different light conditions

  • Alexa and Google Assistant compatibility

5. Ring Indoor Camera - Alexa compatible

The article today doesn’t have a budget choice. The next thing we want to talk about is a security camera. The Amazon Ring Indoor Camera, hence the name, was manufactured and designed both by Amazon. We are certain that many of you have heard of the Ring brand before. Made by Amazon, you should have a peace of mind that it works seamlessly with Amazon Alexa and all the lineups ranging from the Echo lineups to the Fire lineups.

The Ring Indoor Camera doesn’t feature a fancy camera. In fact, the details about the resolution of the camera have not been disclosed by Amazon. Instead, the camera shows itself a real smart camera with all the features including the mic and the speakers for you to talk to people from your Amazon devices, the Wi-Fi connections, the Ring system grid which combines multiple Ring devices into a giant network, and the ability to store your videos on the cloud for up to 60 days.

  • Amazon Alexa compatibility

  • Wi-Fi

  • Mic + Speakers to talk to people from your phones or tablets.

Buying Guides

1. Smart hub

Smart hub works as a control center for IoT devices. Smart hub was initially designed for Bluetooth IoT items to help them connect to the Internet. Some of the smart home devices nowadays still operate on Bluetooth and require the smart hub. However, some of them have skipped the hub barrier and jump right onto the Wi-Fi stage. They can now have their own Internet connection to be connected to your phone.

Consequently, smart hubs don't play the role as important as before but now act as a center to manage and do bulk actions. While we’re not sure about the future of smart hubs, buying a hub is still a good choice today.

2. Wi-Fi

We will talk about kinds of connections to connect to the best smart home devices. Wi-Fi connections currently don’t seem to be the popular type of smart lock connections. Wi-Fi, on the other hand, is considered a premium feature in a smart lock. Here are a few reasons why:

  • Wi-Fi consumes more battery than Bluetooth and NFC: Bluetooth version 3 or newer would require even less than 1mW of power to operate at its top performance, while Wi-Fi would definitely require more than that. You do not want to plug in your door or your clock 24 hours a day, so Wi-Fi is a monster that consumes batteries like fire.

  • Wi-Fi requires more processing power to the chip: A high-performance chip or IC and advanced operating system would be required to operate the Wi-Fi part, because Wi-Fi comes with encryption, signal coding, and everything in between. Typically, an embedded computer made with an ARM chip is used in this situation.

These are the advantages that Wi-Fi connections bring back to us:

  • The ability to be controlled from everywhere on earth: Wi-Fi enables devices to connect to the Internet, so the lock is not bound to the local household or the hub but open to the whole Internet. A user can control the lock from a certain place on Earth with an Internet connection, allowing us to monitor or allow the guests to enter and wait inside while we are heading home.

  • Wider range of devices: Devices can now work with smartphones, smart watches, TVs, tablets, or automation systems that don't have Bluetooth.

  • Security: Bluetooth uses little energy but compromises with security. In fact, studies have shown that Bluetooth chips aren’t designed to handle complex security tasks, so you would not expect an uncrackable Bluetooth lock, or to be more precise, you would not expect a Bluetooth lock that is protected from the outside world at all.

With Wi-Fi and the HTTPS protocol over the web protocol, you can be confident that only you would be granted the permissions to open your door.

3. Bluetooth

Most smart home devices are compatible with Bluetooth and Bluetooth smart hubs. However, Bluetooth doesn’t seem important to Wi-Fi enabled equipment. In fact, Bluetooth shows its advantages when the Internet connection is unavailable to both the lock and the unlock devices such as phones or tablets. Here is the list of reasons why Bluetooth is still a great choice for smart home devices:

  • Energy usage: As we mentioned earlier, Bluetooth uses much less than 1mW to operate at peak, so there is absolutely nothing to worry about. A pair of normal CR batteries can power the light bulb or a sensor for years without worry about replacement.

  • The ability to replace Wi-Fi when not available: When Wi-Fi is out of reach, using Bluetooth is ideal. First of all, Bluetooth is nearly available on most devices. Secondly, despite the fact that Bluetooth itself is not secure, the Wi-Fi processors can be powerful enough to create another layer of security on top of Bluetooth to protect users’ information.

  • The near range: As a disadvantage of Bluetooth, the near range of operation is also an upside in some situations. The near range senses when the users come near the device to automatically turn on and off the lights, unlock the door, change the air conditioner’s temperatures. It also acts as a sensor for the thieves, because if you need to crack the door’s password, you have to get near it for the Bluetooth signal

4. The battery of the smart home devices

A smart light bulb would definitely not require a battery to work, because it works with the direct electricity current to the bulb. However, equipment like the door lock, the gate sensor, and many else need a battery to operate. These are the types batteries often used in smart home devices

  • A/AAA/CR battery: These types of batteries are easy to be replaced, but replacing the battery requires the devices to be taken apart, thus, affects the waterproofing capability of the device. An A or AAA battery can be able to support the lock for at least 3 months up to 2 years, while CR3023 would be enough for years.

  • Built-in rechargeable battery: It requires to be plugged in once in a while, in order to keep working normally. The period of charging may be around 6 months or a year, so it wouldn’t be much of an inconvenience.

  • Solar-powered: This type of battery is the coolest, which doesn’t need any efforts from the users’ side; however, it is not suitable for indoor items or items in dark areas that don't have the sunlight directly shine on.

5. The compatibility

These are the most anticipated features and connectivities for smart home devices. Feel free to email us if you want us to add any features to the list.

  • Phone/Mobile app: Mobile apps are great ways to allow you to control your devices from your phone from anywhere in the world. Mobile apps would also provide excellent security if that involves unlocking your door or checking your house’s status.

  • RF card/NFC connection: This feature allows light bulbs, doors to be unlocked with a ring, a card, or smart watches.

  • Face recognition: The devices would be able to recognize your face even from far away. With the integration to the security cameras, the house could tweak the light configuration, air temperature, music, etc. to each person’s preferences.

  • Voice control: Control your light bulbs, set the room’s temperature, or change your TV channels with your voice. This feature works with a specific set of AI Assistants depending on your smart hub kit. For example, Apple HomeKit would definitely work with Siri, while Google Home and Amazon Home work with Google Assistant and Amazon Alexa, respectively.

1. Should I be worried about the security of my house?

There are two types of security you should know before buying your smart home devices:

  • The security coming from the hardware side: This type of security is not usually the type of thing you should be worried about.

  • The security from the software side: You should worry about situations when your phones are stolen or your cameras are hacked, which would lead you to the privacy circumstances. To avoid this, make sure you have all your equipment updated with the latest security updates, along with keeping your mobile devices secure.

2. My Wi-Fi smart lock doesn’t work, what should I do?

If your Wi-Fi lock doesn’t work, the procedure for your should be:

  • Sit back and check when you last replaced the lock’s battery, or the power is plugged in.

  • Use a screwdriver to take apart the battery compartments and see if they batteries are well inserted.

  • Use a screwdriver to take the device apart to check for anything that would cause the lock to be stuck.

  • Finally, if none of these worked, take the lock to a warranty service of your brand.

3. What about the warranty of my smart home devices?

Smart home devices are usually warranted for 1 years at least. For tops value, the warranty period can last up to 5 years for generous brands. If you purchase an Amazon device on the Amazon website, you’ll also get a free refund or 1-1 exchange when you have trouble with your items.

4. Is my device waterproof?

Well, 50-50. Locks, sensors or outdoor lights are waterproof because they need to withstand extreme weather. However, indoor lights, plugs, or outlets are not. 

Therefore, do not attempt to test your devices with water and other types of liquid unless you are under protection, for you could cause injury to yourselves.

5. How do I install my device?

Depending on your device, you might need to use different procedures. However, the common steps are:

  • Remove your existing devices, such as the outlet, locks, etc.

  • Use a screwdriver to install the new ones.

  • Use your phones and follow the instructions to set up your devices before using them.
