A Comparative Analysis of Smart Home Automation Technologies in the UAE

The Smart Home Automation industry in the United Arab Emirates (UAE) has been growing at a rapid pace since its dawn over the last several years. The market is becoming more and more aware of the capabilities of having a complete automation system whether at the scale of individual residences, palaces, real estate developments, and hotels. Many developments in Dubai and Abu Dhabi have already been completed with a pre-installed automation system. Many developments in areas like Victory Heights, Arabian Ranches, Sports City, and Reem Island have also been built with infrastructure to support such technologies in the future.

In basic form, automation includes systems that control Lighting, Appliances, HVAC, Curtains and Multimedia. The market in the UAE has not only begun to realize the benefits in terms of comfort, security, and luxury. But also in terms of energy saving and increasing property value, thus all these realizations will continue to lead to a booming market in the UAE.

As automation is somewhat of a new technology in the mainstream market, one must be aware of the countless number of underlying technologies that connect and allow for the communication between a user and the Light Dimming Systems or Air Conditioning Systems. On the surface, these technologies may seem to lead to the same functionality, but in the back-end, they are different in potentially catastrophic ways. This leads us to the reason why we started composing this article, that is, to shed light onto the pros and cons of the different technologies (regardless of product or vendor) which are available in the UAE market today.

Any automation system is composed of 2 high-level components, the controller, and the modules. The modules include light dimmers, relay switches, thermostats, motorized curtain control systems, distributed speakers..etc. which are to be controlled by the home owner. The controller, is the heart of the system from which signals are sent to “Dim the lights” or “turn on the air conditioning”. The method of communication between the controller and the modules are the Automation Communication Technology which we wish to address in this article. The method of communication can either be through wires or wireless and are usually in line with certain protocols or standards of communication. This article will explore and compare KNX, X10, Zigbee, En-Ocean, and Z-wave.

The criteria for comparison which we will explore are the following:

Reliability of Communication: How reliable is the communication between the Controller and the Modules? When a message is sent to a module, the system must ensure the message’s arrival and confirmation of receipt. Scoring well in this criteria is very important to ensure that even under circumstances of wired or wireless interference messages are resent until confirmed by the receiving module. Not all protocols comply with this requirement.
Security of Communication: The protocol must guarantee that a 3rd party cannot infiltrate an existing system and operate it with unauthorized access. The results of a hacker entering a parking lot of a hotel and turning all its lights off is disastrous.
Price
Features and Capabilities: It is important that automation technologies go beyond just controlling individual modules and have the capability to integrate with other systems most typically entertainment since that is an area of high usage of any home owner. Example: Easy Integration with Multi-room Music Systems, Multi-room multimedia distribution systems (Movies, Videos, Pictures, Music)…etc.
Investment Protection: It is important to make sure that installed Controller or Modules can be easily replaced in the future. Consider having installed a system that has some components fail after 5 years, and at the same time, the company which installed it became bankrupt. The home owner would be left with no choice but to completely revamp the entire electrical system in the residence which would cost more in time, labor, and equipment that what was originally paid for the automation system. Having a system that is standardized means that any other company can support it or replace certain parts with different products, maybe from different vendors, in order to ensure continued operation.
Interoperability: This criteria refers to the capability of the Controller to speak to multiple Modules from different manufacturers. This will ensure that a system is made up with Lighting, HVAC, Curtains, Appliances, and Multimedia Control Modules are purchased from different manufacturers which are the best or most specialized in those fields. This ensures that a system has the best-in class Modules for each particular purpose. It is not logical that the best manufacturer of light dimmers is also the best manufacturer of curtain control systems, or audio systems. Some communication protocols are closed or proprietary, thus forcing the customer to purchase everything from a single manufacturer. This criteria also overlaps with the Investment Protection Criteria since having an interoperable system will give future flexibility to easily replace Modules even if the company which installed them has closed down.

The remainder of this document will address each communication technology based on the above criteria.

KNX

KNX is an international standard of communication typically installed in wired twisted pair environments. KNX was designed in 1990 and was made as a very robust protocol to be used in industrial automation applications. The protocols reliability cannot be questioned since it implements many OSI communication layers and is quite complex. KNX is also controlled by the KNX association and any company usually spends thousands of dirhams on their employees to go through training in order to understand the inner workings of the system. KNX is a complex protocol by nature, and was designed long before the “smart home” concept was born, thus the hardware that has the capability to support the complexity of KNX is expensive not only to engineer, but also to manufacture and thus the hopes for this technology to become cheaper than its current alternatives is futile.

KNX has and is a popular choice for hotels since 2006 and has been deployed in many developments such as the Shangri-la in Dubai, Rotana Hotels in the Marina, Fairmont, Movenpick to name a few. KNX is also being specified by many real estate consultants for major developments in the Abu Dhabi Reem Island and Yas Island.

Reliability of Communication: Yes
Security of Communication: Yes
Price: No
Features and Capabilities: No. KNX has been more focused at the simple facility of automation and typically fits in hotel environments where customization and multimedia integration is not required.
Investment Protection: Yes
Interoperability: Yes

X10

X10 is an international open standard developed in 1975 by Pico Electronics of Scotland, in order to allow remote control of home devices and appliances. It primarily uses the 220Vpower line wiring for sending messages between the Controller and the Modules (Lighting, HVAC…etc).

X10 has only receyved some popularity many years ago when automation technology started being introduced in the UAE. And was typically installed in small villa project then was slowly discontinued due to its reliability issues.

Reliability of Communication: No. Since it is prone to interference from multiple sources like transformers, motors typically found in TVs, washing machines, fans…etc. Also, messages from Controller to Modules are never acknowledged so there is no 2-way communication.
Security of Communication: No. If a 3rd party can tap into the powerline of a house, messages can easily be sent to control whatever the 3rd party wishes.
Price: Yes
Features and Capabilities: Yes. This technology can easily be integrated into PC based systems and many options are available to provide feature rich capabilities for residential applications.
Investment Protection: Yes
Interoperability: Yes

Zigbee

ZigBee is an open wireless network communication protocol based on the IEEE specification IEEE 802.15.4, which enables the Controller to communicate with its Modules via Radio Frequency. The standard is a development of the ZigBee Alliance, which was founded in the end of 2002. It is an industry alliance of more than 230 enterprises who take up the worldwide development of this technology. The first ZigBee products came on the market in the beginning of 2005. Because Zigbee standardises only the lower protocol layers (radio layer), the different manufacturers have defined their own higher software layers. As a result ZigBee devices of different manufacturers are not compatible with each other.

Reliability of Communication: Yes. A wireless mesh network is created and ensures multiple path routing to every module which translates to long reach, and high reliability in case of interference or even in case of in-path device failure.
Security of Communication: No. Zigbee uses weak hashing algorithms and has been researched to be penetrable. Penetration is not easy but software tools such as “Killerbee” exist and can allow any person with little Linux and scripting experience to hack into an existing Zigbee network.
Price: No
Features and Capabilities: Yes
Investment Protection: Yes
Interoperability: No

En-Ocean

EnOcean is a wireless radio frequency based, energy harvesting technology used primarily in building automation systems. It is not set out for international, European or national standardization; however, EnOcean GmbH is offering its technology and licenses for the patented features under license within the EnOcean Alliance framework. The concept was developed to enable batteryless sensors and switches for building automation. Which is questionable in terms of energy saving because existing alternatives can consume as little as 500W per 60 storey tower in automation devices.

EnOcean based technologies have been installed in some big projects such as the Abu Dhabi Central Market, the Dubai Financial Center…etc.

Reliability of Communication: No, En-Ocean does not offer 2-way communication between the Controller and its Modules. Also the Controller is at a star network with the Modules and there is no wireless meshing, this one-to-one signal mapping can drastically fail in times of high interference.
Security of Communication: Yes
Price: No, En-Ocean prices are more aligned with KNX.
Features and Capabilities: No. Supported but not yet seen in the market.
Investment Protection: Yes
Interoperability: Yes

Z-wave

Among all the above protocols, Z-wave ranks the best so far. The strength of Z-wave lies in the big number of different products from different manufacturers as well as the very robust, 2-way, meshed, and secured wireless communication. Z-wave chips also consume a 10mW at peak and are low cost compared to all other alternatives. Why? because Z-wave has been originally designed for residential applications.

Z-wave is viewed as the next generation of Smart Home Technology and product lines have started to emerge from big players such as Honeywell and Schneider Electric. This technology is not only feature full, reliable and secure, but will be offered at competitive prices and investment protection for projects of any size starting with individual villas all the way to large real estate towers. As of today, Z-wave has been deployed in many villas in the UAE at an individual scale. Z-wave is also starting to make its way through many of the large tenders for developments throughout the Emirates.

Reliability of Communication: Yes
Security of Communication: Yes
Price: Yes
Features and Capabilities: Yes
Investment Protection: Yes
Interoperability: Yes

Easy Ways To Do Laptop Data Recovery In Perth

As electronic storage devices get cheaper, we are increasingly becoming dependent on them for data storage. If we hold on to our memory cards and flash drives for too long without transferring the files to a secondary storage device we might accidentally erase them or the devices might get corrupted. Also our laptop might start malfunctioning due to a logical damage to the operating system and the data in its hard disk becomes inaccessible to us. Don’t panic! Here we are going to discuss about easy ways to do laptop data recovery in Perth.

Data recovery is the process of retrieving impassable data from damaged or debased secondary storage devices and removable files that cannot accessed in a traditional way. There is USB flash drive data recovery, external or internal hard disk drive data recovery, CDs and DVDs data recovery etc. This scenario evolves when there is an operating system failure, malfunctioning of internal or external storage device and accidental damage or deletion of files. Data corruption occurs due to physical damage to the storage drive or logical damage in the file system which prevents access to the data. Mechanical or physical damage to the storage drive will cause at least some data loss and also logical failure in the drive. If it occurs then users will have to take help from professionals for data recovery.

Usually companies providing data recovery due to physical damage have class 100 dust free room so that it does not get settled on bare disk drives. Logical damage is a software level damage which occurs due to partition errors in the file system or if the data gets overwritten. Generally in case of physical damage, enterprises providing laptop data recovery in Perth, takes care of logical damage before hardware repair and recovery. Repairing physical damage to disk drives and also data recovery from it are costly but there are many companies providing better and cheap deals.

DIY laptop data recovery

For logical damage to storage drive, the data remains intact in the drive but becomes impassable which can be recovered following the steps given below

Step 1: Purchase a hard disk drive enclosure online. Make sure that you purchase an enclosure according to the specification of your corrupted laptop. The enclosure turns the corrupted hard disk drive into an external storage device connected using an USB cable.

Step 2: Use a working computer which will be compatible with the operating system of your old laptop. For e.g.: if your damaged laptop is windows, then use a computer having windows operating system. Though Linux can also read data from windows still it’s better to stick to similar operating system.

Step 3: Unscrew your old laptop and locate the hard drive which is of the size of a 3.5 inch floppy drive. You can also look for the location of hard drive of your laptop model online.

Step 4: Connect the disk enclosure’s connector plate with your hard drive connector interface. Insert the disk drive inside the connector and screw it shut for enclosing.

Step 5: The new drive will automatically open on the working computer when it will be connected with the USB cable. A notification will pop up for windows users or an icon appears for Mac users. If it is not recognized, eject it and plug it back to the computer. For non readable hard drives, you will need professional assistance.

Step 6: Once you can open your external drive on the working computer, explore it and restore the files on the working computer or use the computer as a transfer device to transfer the file into another external storage device.

Step 7: After recovery of files from the storage drive, close the window and eject the drive.
