A Knockout Post
As automation is somewhat of the new technology in the main-stream market, one must certanly be aware of the numerous number of underlying technologies that connect and allow for the communication from a user while the Light Dimming Systems or Air Conditioning Systems. On the surface, these technologies might seem to lead to the exact same functionality, but in the back-end, they`ve been different in possibly catastrophic ways. This leads us to your reason we began creating this article, that is, to shed light onto the advantages and disadvantages of the technologies that are differentregardless of product or merchant) which are available in the UAE market today.
Any automation system consists of 2 components that are high-level the controller, as well as the modules. The modules include light dimmers, relay switches, thermostats, motorized curtain control systems, distributed speakers..etc. Which are to be controlled by the true home owner. The controller, may be the heart regarding the system from which signals are delivered to "Dim the lights" or "turn regarding the atmosphere conditioning". The method of interaction between your controller plus the modules are the Automation Communication tech which we wish to address in this essay. The method of interaction can be through wires either or cordless and tend to be usually in accordance with specific protocols or requirements of communication. This article will explore and compare KNX, X10, Zigbee, En-Ocean, and Z-wave.
The criteria for contrast which we will explore are the following:
Reliability of Communication: just how reliable is the interaction involving the Controller therefore the Modules? Whenever a message is delivered 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 also under circumstances of wired or cordless interference communications are resent until verified by the getting module. Only a few protocols conform to this requirement.
Security of Communication: The protocol must guarantee that the party that is 3rd infiltrate a current system and run it with unauthorized access. The outcomes of a hacker entering a parking large amount of a resort and switching all its lights off is disastrous.

Reliability of Communication: Yes
Safety of Communication: Yes
Cost: No
Features and abilities: No. KNX has been more focused at the simple center of automation and typically gels hotel surroundings where modification and multimedia integration isn`t needed.
Investment Protection: Yes
Interoperability: Yes
X10
X10 can be an international standard that is open in 1975 by Pico Electronics of Scotland, to be able to enable remote control of home devices and appliances. It mainly makes use of the 220Vpower line wiring for sending communications between your Controller and the Modules (Lighting, HVAC...etc).
X10 has only receyved some appeal years ago whenever automation technology started being introduced in the UAE. And was typically installed in little villa project then ended up being slowly discontinued due to its dependability problems.
Reliability of Communication: No. as it is at risk of interference from numerous sources like transformers, engines typically present in TVs, washers, fans...etc. Also, communications from Controller to Modules should never be acknowledged so there isn`t any communication that is 2-way.
Security of Communication: No. In cases where a party that is 3rd tap into the powerline of a home, communications can simply be delivered to control long lasting 3rd party wishes.
Price: Yes
Features and Capabilities: Yes. This technology can simply be incorporated into Computer based systems and options that are many offered to offer component rich capabilities for domestic applications.
Investment Protection: Yes
Interoperability: Yes
