Home Automation Networking through Home Electronic System
The international standard, although relatively slow, has a​ large participation in​ the​ trade of​ ideas between developers of​ home automation around the​ world .​
The application models specifications promotes the​ interoperability of​ the​ products .​
This is​ considered worthwhile then focusing on the​ latest protocols .​
There are reports written to​ lead energy utility corporations to​ develop new consumer services which utilize networks for​ home automation .​
This led to​ the​ development of​ home automation networking international standard called as​ HES (Home Electronic System) .​
Just recently, this material has been updated and​ reflects its progressive results .​
The HES primary goal is​ to​ identify software and​ hardware so that manufacturers can offer one product version which could operate on a​ wide range of​ networks for​ home automation .​
There are several HES components needed to​ accomplish this objective .​
- Universal Interface .​
This interface module is​ integrated in​ the​ appliances to​ allow communication over different networks of​ home automation .​
The HES primary goal is​ to​ establish communication between appliances on any communication network of​ home automation .​
UI or​ universal interface is​ incorporated to​ the​ appliances including the​ standard data plug .​
The standard language application is​ likewise developed to​ all messages and​ commands of​ the​ appliances .​
Each connection points on the​ network contains NAU (Network Access Unit) which convert the​ appliances messages and​ data signals to​ a​ specific communication protocol of​ home automation .​
HES identify the​ protocol of​ communications between the​ NAU and​ the​ IU .​
- Command Language .​
The language utilized by appliances to​ communicate with each other regardless of​ the​ network where messages are being carried .​
The HES language accommodates the​ commands of​ the​ networks .​
However the​ interposing of​ NAU-IU link among appliances and​ network mediums cannot optimize the​ operation of​ the​ home automation system but it​ reduces costs when sold in​ a​ large market .​

- HomeGate .​
This residential gateway links control networks at​ home to​ the​ external networks of​ service providers .​
The primary function of​ the​ gateway is​ to​ translate protocols among WAN (wide area network) and​ LAN (local area network) .​
This contains features of​ a​ firewall limiting messages which can flow inside and​ outside the​ house .​
The working group on HES is​ also licensed for​ investigating network applications on communications, control, and​ command in​ mixed-use and​ commercial buildings .​
Apartment houses having offices and​ retail shops belong to​ the​ mixed-use buildings category.
The subsystems and​ appliances designers makes the​ decisions concerning variables and​ functions which can be accessed from other gadgets within the​ networks of​ home automation .​
In engineering language, these are options concerning controllability and​ observability .​
There must be a​ consistency in​ these decisions so that the​ devices can successfully interoperate .​
The application model explains the​ device engineering aspects which can be written, executed, or​ read through the​ networks .​
This model is​ important to​ convey information to​ the​ product's manufacturers which will be connected by a​ network for​ home automation purposes .​

Major protocol never includes the​ subsystem model's complete application within its specifications .​
Checking of​ objects which comprise an​ application can infer a​ model .​
The selection of​ methods, variables, and​ objects are patterned on how the​ communication interface designers understand the​ device .​
This information needs to​ be completely described in​ the​ application model .​
Otherwise, the​ manufacturers can misinterpret details on operation of​ the​ device since they don't have staff or​ network experts having familiarity with the​ models of​ communications .​
The countries which are considered as​ Principal Members have approved HES models for​ publications including energy management, security, and​ control system .​
The Working Group of​ HES examines functional safety issues .​
Thus the​ IEC (International Electrotechnical Commission) Advisory Committee of​ Safety requested the​ Working Group to​ develop guidelines on home automation network safety .​
The safety messages that are considered critical must be confirmed before it​ will be sent throughout the​ network .​
The appliances operation through the​ network does not compromise its safety aspects .​
Thus, in​ case of​ network failures, the​ device maintains the​ appropriate levels of​ safety .​
There are safety standards provided by IEC for​ various devices when they operate individually .​
The ACOS main concern is​ that interaction between products via home control networks obtain the​ safety requirements harmonization .​
Functional safety is​ defined by the​ IEC as​ the​ home control system's capability to​ execute actions essential for​ maintaining and​ achieving desired levels of​ safety within normal situations and​ emergency cases .​
