Smart Home Guide
Smart Home is an electronic system with computer software that allows control of any electrical and electronic equipment, and integration with other systems .
When choosing a system should take into account, that we are dealing with electrical equipment working continuously for a few/several years. It is worth to buy the system , wherein the time “life” of electronics is not calculated for 3 – 4 years .
In addition, systems require specific installation and intervention in the electricity and the need for repair, maintenance, calibration.
To enjoy home and building automation for many years, should take into account not only the unit cost of system purchase , but many other factors as the replacement system and the installation of smart home , associated with a renovation or in extreme cases, the sale of the house :
- usability and functionality
- the opportunity to develop and upgrade the system
- development of electronic technology and information
- service , tests , calibrations , inspection
- wear on electronic components and actuators (relays) , lifetime , aging of the elements , equipment life
- safety , electric shock , Breakthrough for high voltages
- resistance to the human factor , users , children
- exposure to damage other devices
- optimal working conditions: moisture , temperature , voltage stability , interference
- technical conditions , technological building and its size
- the number of control points , control
- span installation , distance points controlled from one another
- The use of electronics manufacturing technology : for example, compliance with RoHS greatly reduce the life of the electronics to (3 – 5 years ) . All systems “Plug & Play” require adherence to standards RoHS (lead-free assembly)
In the case of drastic renovations or construction of new homes, buildings wired systems are many times more reliable, stable, longevity of wireless .
In the event that you can not interfere with the installation of a building used radio systems or communicating the grid but this is a last resort .
1 ) Radio systems use radio waves for wireless communication between controllers .
Certainly residents will not long enjoy the installation of smart home radio systems, especially battery, when they have every few weeks to replace the batteries in each controller.
They are also easily obstructed and sabotaged by transmitting more power than the small drivers on the walls. In addition, are significantly influenced by aging (particularly elements responsible for receiving and transmitting radio signals) . Most of the works on standard amateur or WiFi frequencies where there are conflicts, or at least more battery usage. These devices need to be replaced with new ones in period 3 to 5 years from the date of installation or production, which should also be taken into account before purchasing.
Their work is also affected by changing ambient conditions , new systems within work , GSM base stations , monitoring radio-lines, used construction techniques and sometimes even setting home furnishing items.
Battery replacement and services are associated with getting to the electrical boxes, which is generally installed electronics with actuating relay and voltage 230V.
In addition, there is a risk of electric shock and / or fire in the event of a puncture to the mains voltage as a result of getting insects or rodents to electronics . controllers are virtually unrepairable and must be replaced regardless of what becomes damaged.
2) Another type of system requires a fairly small interfering with the installation of electrical systems are using electricity network to transmit control signals. In fact, beside power has the same disadvantages as wireless systems. They are more fully described in the post :
3) systems which require a dedicated installation.
They require installation on the condition of the electrical installation or repair . Despite this, have a much longer life, stability and safety and work in optimal conditions. Drivers installed in the wall socket , also pose a risk of damage or blocking the entire system for damage control.
Among the best of these are systems installed in the mini-switchboard on the premises or central switching where there is a large distance between the part of the Low Voltage (electronics ) and 230V where there is practically no possibility of accidental break or short circuit to high voltage.
In addition, they are much more easily serviceable than controllers hidden in a wall socket (cans). smart house eHouse in three versions to meet the highest standards for safety in professional installations :
- eHouse One – RS-485 installations dedicated especially large and very large objects (hotels , office , houses , apartment buildings ) with a very large total length of the plant (up to 1200m without extensions) – to create professional mini – switchboard
- Ethernet eHouse – LAN dedicated as the previous system with another type of communication interface (standard computer network)
- eHouse.PRO – Dedicated LAN centralized installations and large central switchboard for the entire facility or hybrid installation ( integrating other versions of eHouse )
Due to the unique design of controllers and low voltage nature of the work we are not obliged to comply with RoHS standards.
Drivers are not executed in Compliance technology so that the life of drivers is estimated at around 15 – 20 years .
We have a fully functional installations and controllers issued in 2000.
Design experience and knowledge gained since then has enabled us to produce professional, long-lived systems and installations, even when self assembly for people who have never dealt with electronics or electrics .
These systems have a distributed electronic part (low voltage to 12V) from the relay regulations and voltages 230V , so that there is virtually no risk of penetrating the external voltage to the system , fire etc. . Relay contacts for damage can be replaced on relay module even yourself ( they are in sockets for DIN rail) , without having to replace the entire controller as in other systems .
Electronic modules are not in the electrical boxes , but in a mini – switchboard, central switchboard or external enclosures, This makes them much more accessible and exchange takes far less time.
The use of quick-assembly IDC sockets allows you to express disassembly and reassembly in less than 1 minute , despite the huge amount of I/O drivers (50 to 520).
Electronic controllers are modular (segmented) and designed to replace the failure of one does not affect the operation of the entire building automation system .
Inputs are of the type of communication interfaces “hot plug” and allow you to disconnect the drivers live, without interfering with other segments of the installation.
Service , tests , measurements , calibrations , upgrade software or configuration is performed remotely from a PC without having to physically connect to the controller.
In extreme cases (e.g. . questionable accuracy of installation or wiring ) , controller can be unplugged from faulty installation and tested “on the desk” using the evaluation / demonstration unit.
Controllers configuration can be similarly carried out on the desk , and not in a production plant on the site , which it is much less convenient and significantly reduces the possibility of errors during configuration and installation of the system in the building .
