eHouse LAN – Demo House 200m Comfort Installation

The Intelligent House, Building Automation eHouse LAN can be controlled via Cloud eHouse Cloud .
This is another option besides direct access through eHouse for Java , Android (TCP / IP, UDP, SMS, eMail) and web browser.
One control method does not exclude another.

The following project is a comfort installation system (one controller per room) with full access from outside. eHouse LAN demo project was discussed in earlier posts:
The installation realizes the complete automation of the building ~ 200m2 (ground floor, floor) – in the comfort version.
The system is based on eHouse PRO server and eHouse LAN controllers for small switchboards (all inputs / outputs from single room goes to room switchboard).

“Working in the cloud” is the synchronization of system data with the Web server and MySQL database.

Advantages of Cloud:

  • Can work with any Internet connection without any restrictions
  • does not require public access Internet
  • Does not require a fixed IP address or DDNS service for the link
  • No complicated configuration of NAT Internet Router, sharing and redirection of Ports, Servers, DMZ, etc.
  • If you work on the web, it can be controlled from any device with a web browser

Disadvantages of Cloud:

  • Higher link load and data transfer
  • slower, refresh and delay than direct access (3 to tens of seconds of refresh)
  • depends on the stability of the WWW/MySQL server
  • loads the WWW/MySQL server and needs a large data transfer for each installation

To reduce disposing of the link and web server/MySQL, the refresh is set to 60 seconds when the client is not connected to the cloud. In case of connection and start up of the system command, the frequency increases (up to several dozen or so seconds) depending on the configuration.
Because it requires a web server, it is a paid service that depends on the amount of data transferred (transfer rate and refresh rate).

At: eHouse LAN + Cloud Building Automation is publicly available (without passwords) Centralized demonstration system installation. It is also an eHouse PRO test installation for BMS system integrators to test the system without eHouse hardware.

Examples of visualization of eHouse by the Web (SVG + JavaScript). Architectural (created with the help of CorelDraw with eHouse scripts) and generated automatically based on system configuration.
Because visualizations are in text files, it is easy to edit and change.

eHouse LAN Home Automation – Mini/Midi Switchboard Installation

eHouse LAN RoomManager – Building Automation, connection at the building.
Installation of a mini-switchboard and midi-switchboard in a residential building.

We can install the small room switchboard in place, that will eventually be covered with light furniture.
The point is to allow easy access to the switchgear, if service is needed, and to avoid marring the room where it is installed.
The switchgear can also be installed in adjacent rooms (eg utility rooms), which require increase in cable length.

Installation of the switchgear on the wall:
The switchgears are concealed with detachable frames so we can remove them until finishing the walls (including final painting).

This article is instructional and boxes and cans are screwed directly to the wall, without drilling wholes for it.
In the normal case, wholes should be cut under the switchboard and cans to determine the proper depth of foundation of these elements.
Flat strips (for low voltage inputs) do not require forging furrows because they are about 2mm thick.
We fix the switchboard on the wall preferably at the height of electrical sockets (it has several mounting holes in the side and back of wall ).

eHouse LAN Building Automation - Switchboard

We dismantle the frame so as not to damage or scratch it.

 Building Automation

We mount electrical cans in the wall (preferably 6cm deep).
Cans mounting

If we do not have prepared IDC-16/14 wires for the infra-red panel / switches, we clip them. It is necessary to clamp at right angles and make sure that the tape does not move when clamping.

The plastic insert of the crimper should be glued with insulating tape so that it does not move.
Clamping IDC cables

The connector is marked with an arrow next to pin no. 1, while the flat cable with red color is marked with cable no. 1 (should be adapted with each other).
Clamping IDC cables

We connect the flat cable of the infrared panel to the appropriate “IR Panel” connector to measure the length of the wire we need. The tape should be kept at a minimum distance of 20cm from 230V interfering wires and communication interfaces (eg Ethernet).
The infrared panel contains: temperature sensor, lighting sensor, infrared transmitter and infrared receiver.
To perform all its functions correctly:

  • must be installed in front of A/V equipment which it intends to control at a distance of less than 8mb and must “see” this device.
  • if we intend to correctly measure the temperature, it should be as exposed as possible in a place, where there is good air exchange (at a height of 1.5 m from the floor)
  • the length of the flat cable must be less than 8m
  • ensure the distance of this tape over the entire length of 20cm from other wires

connection the IDC-16 cable of the infrared panel

We spread the flat tape only vertically and horizontally (no slants), gluing it, eg with a glue gun, to withstand the plastering process or gluing G-K boards.

Cutting the cable with sharp scissors with reserve of 20-50cm. If you intend to place the panel outside the electrical box, you can increase this length.

We clamp the IDC-14 quick connector for on/off inputs (switches). In the controller it is necessary to tighten the 14-pin IDC connector. You can do it on the IDC-16 flat cable by pulling the last 2 wires. However, they may be useful in the future, for example, to connect the illumination of sockets or in situations when a cable breaks during construction works.

Making a loop in cans at least 5cm above the top of the box so that you can tighten IDC-14/IDC-16 quick connectors.

The tape is further fed in series to subsequent cans of switches. It is possible to duplicate the switches in various places of the room.

Connection of electrical devices to relay contacts:
Rail “COMB” make contact shorten of all connections (common “COM” relays) – work on one phase.
Neutral “blue” wires are connected on blue rail.
The yellow-green protective conductors are connected to yellow rail.
Electrical devices (phase) are connected to the NO contact (Normally open) of the relay.
The comb can be cut to control the devices for various voltages.

Connecting the first electrical circuit to the relay contact:

The switchgear must be protected by a over-current and differential-current fuse, placed for convenience in the central switching station and not in the mini-switchboard, due to easier access, especially when the switchgear is covered with furniture.

In order to protect against mechanical damage of flat tapes by construction crews, it is worth covering them with reinforcement mesh for expanded polystyrene (width ~ 10-15cm) and apply adhesive to styrofoam.
This will also prevent the tapes from unsticking in case they do not stick too well.

eHouse LAN Home Automation system – opened protocol of communication

eHouse LAN, PRO, Wi-Fi Smart House can be integrated with any systems / devices and software through open protocol TCP/IP and UDP.
It is possible to send control commands to each eHouse LAN, Pro, WiFi controller using TCP/IP client application. To create your own software, there are 3 types of authentication to the controller:

  • XOR Password – password hashed variable code received from the server
  • plain password – a simple password
  • No checking authorization – open access

It is required to set the minimum desired level of authorization for each controller configuration. Safer methods of authentication are also active for the visualization panels and eHouse system applications for configuration.
eHouse LAN, WiFi, PRO controllers send their status as the UDP broadcasts, so that any number of panels can receive this information in a common LAN.
