Smart home installation guide eHouse building for self-assembly.

EHouse system - Smart home, An intelligent building for every pocket, requirements and expectations.

Many people build a house, I do not decide to use home automation, due to the high costs of these installations (up to PLN 100,000 for a house with an area of 100m2). These systems in our country are treated as luxurious equipment for a very high price. Facing investors, who due to the limited budget give up intelligent installation, we want to present a solution, which will be much cheaper and as good as the smart home systems from the top shelf " financial ".
Smart home eHouse is a solution, in which, unlike other systems, one does not pay for a single lamp or an on / off switch, but for the entire driver (RoomManager - allowing to connect up to 24 electric receivers, 12 switches or digital sensors, 8 analog sensors). It is a device that integrates a conventional electrical installation with an intelligent one, not imposing on the investor specific elements of finishing the house. In addition, the design and installation can be done in-house, by the investor or commissioned to a local electrician or installer.
Below, we present a set of documentation enabling independent installation of the eHouse smart home system.

Installations of the Smart home eHouse can be divided into a few steps:

Installation of low-voltage wiring

Arrangement relay modules and connecting to them data bus (RS - 485) and Supplying the eHouse system (+ 5V, 0V, + 12V).
Arrangement HeatManager (HM) , ExternalManager ' a (EM) , RoomManager ' those (RM) and connection of wires to the relay module (without powering up the power supply)
Connection of digital switches and sensors to RM, EM, HM ,
Connection of analog sensors to RM, EM, HM ,
Verification by measuring instruments of connections correctness checking of short circuits and connections between modules.
Disconnection of wires from RM controllers, EM, HM, switching on the power bus supply and checking the voltage and current in the system on the power connectors and in the measuring points,
Connection of modules to the power supply,
Installing the eHouse application and connecting a PC to the data and power bus and checking the operation of the entire system,

Installation of high-voltage wiring 230V.

Disconnection of all RM controllers, EM, HM from the relay module
connection of 230V sources by the relay circuit to selected receivers according to the design
Precise verification of connections before switching on automation and power supply devices
Checking the compatibility of supply voltages at a given point in the system with a voltmeter, before connecting the automation.
Connection of 230V voltage to the relay module if required
Repeated checking of supplying voltage or short circuits in the system, which would damage all electronics
Connection of automation systems to cabling.
Checking the operation of the system.

The heart of the smart home system are the RoomManager drivers, HeatManager, ExternalManager. They are all built on a base one printed circuit board and differ only in connected peripheral modules allowing for specific features of a given controller.

The main features of the modules are:

The main differences of controllers	HeatManager	RoomManager	ExternalManager

Smart home system, eHouse building (used connectors, wires, elements) has been designed in this way, to enable it based on the following documentation, very fast installation, even people who are not professional installers of this type of equipment. Additional accessories and connectors needed to install RoomManager controllers, HeatManager, ExternalManager are shown below

RoomManager (RM) driver accessories, ExternalManager (EM), HeatManager (HM).
The main elements of the eHouse system.

To make a smart home installation, you need only a few tools, which simplify and speed up the processing of wires, crimping and assembling the connector, and assembly and disassembly of individual modules. Required tools for installing the smart home eHouse outside the soldering iron are:

Tools for easy wiring installation (system connection clamping).
Wire preparation tool (stripping of leads especially for 230V wires).

Diagrams according to which the installation of the eHouse system should be carried out are below.
Applying unconditionally to these drawings, everyone can do it himself, or instruct the local electrician or installer to install the eHouse system.

A simplified block diagram of the eHouse system installation.

As you can see from the scheme of the eHouse system, it has 2 mains, which create a low-voltage network connecting the intelligent home system modules:

Data bus eHouse (RS - 485 Full Duplex).
Supplying the eHouse system (+ 5V (*), 0V, + 12V).

(*) 5V power supply is the unswitched power supply for relays, in the case of using relays for other voltages (max 12V), this line should be connected with the appropriate voltage for relays

These buses connect the relay modules to each other, which fulfill the function of distributors, enabling the main drivers to be connected to them (RoomManagers, ExternalManager, HeatManager), with a few convenient connectors permanently fixed on the wires. Only the power bus is soldered directly to the relay module, because to ensure trouble-free operation of the system and limiting the resistance of contacts. The instruction for connecting the relay module for the system cabling is presented below:

Installation of the relay module.

The relay module outside the bus distributor has built-in relays, which can be protected by fuses eg. polymer.

Polymer fuses for protection of relays.

For additional protection of the devices, it is possible to insert polymer fuses into the required current and voltage in place of the relays on the relay module.
Relays used in the system for switching on electrical equipment.

The relays are used for switching on and off devices with voltage, current and power less than the rated parameters of relays. To obtain a small contact resistance and good connection with devices connected to the output contacts of relays, these connections are also soldered (which ensures long-lasting and trouble-free operation of the system). This protects against sparking contacts and heating them which occurs, when the contact has a high resistance. In the case of damage to the relays (which is rather unlikely, if we do not connect receivers of too high power or of inductive nature to relays. It is easiest to simply desolder and put in a new place (please remember to disconnect all connectors before doing so), turn off bus power supply (+5, 0, +12) and 230V mains voltage or main fuse.
Alternatively, instead of the relay module, you can use independent relays mounted on the mounting rail in a central or local switchboard. However, it is necessary in this case to separate the RS data bus - 485.
Connection of relay modules with main controllers (RoomManager, HeatManager, ExternalManager) is done with the help of J1 (RS - 485), J2 (power supply + 12V), J5 (digital outputs). The wiring and connection of the appropriate connectors are shown below.
