# IHC / ELKO Binding

This binding is for the "Intelligent Home Control" building automation system originally made by LK, but now owned by Schneider Electric and sold as "IHC Intelligent Home Control" or "ELKO living system" depending of the country. It is based on a star-configured topology with wires to each device. The system is made up of a central controller and up to 8 input modules and 16 output modules. Each input module can have 16 digital inputs and each output module 8 digital outputs, resulting in a total of 128 input and 128 outputs per controller. Controller also support different kind of wireless devices. User can create application logic to the controller to control inputs and outputs, but also create virtual inputs and output, and function blocks.

The binding can download the project file (application logic file) from the controller. Binding will also listen to controller state changes, and when the controller state is changed from init to ready state (controller is reprogrammed), the project file will be download again from the controller.

IHC / ELKO LS controller communication interface is SOAP (Simple Object Access Protocol) based, limited to HTTPS transport protocol.

# Supported Things

This binding supports one ThingType: controller.

# Thing Configuration

The controller Thing has the following configuration parameters:

Parameter Description Required Default value
hostname Network/IP address of the IHC / ELKO controller without https prefix, but can contain TCP port if default port is not used. yes
username User name to login to the IHC / ELKO controller. yes
password Password to login to the IHC / ELKO controller. yes
timeout Timeout in milliseconds to communicate to IHC / ELKO controller. no 5000
loadProjectFile Load project file from controller. no true
createChannelsAutomatically Create channels automatically from project file. Project file loading parameter should be enabled as well. no true

# Channels

List of default controller channels.

Channel Item Type Description
controllerState String Displays IHC / ELKO controller state.
controllerUptime Number Displays IHC / ELKO controller uptime in seconds.
controllerTime DateTime Displays IHC / ELKO controller date and time

When createChannelsAutomatically parameter is enabled, binding will automatically create channels accordingly to project file. Binding create channels for dataline_inputs, dataline_outputs, airlink_inputs, airlink_outputs, airlink_relays, airlink_dimmings, resource_temperatures and resource_humidity_levels, and also channels for wireless device signal strengths and low battery warnings. User can manually add other channels or disable channel auto generation and add all needed channels manually.

List of supported channel types.

Channel Type Item Type Description Supported channel parameters
switch Switch Generic switch channel. resourceId, direction, commandToReact, pulseWidth, inverted
contact Contact Generic contact channel. resourceId, inverted
number Number Generic number channel. resourceId, direction, commandToReact, pulseWidth
dimmer Dimmer Generic dimmer channel. resourceId, direction, commandToReact, pulseWidth
datetime DateTime Generic datetime channel. resourceId, direction, commandToReact, pulseWidth
string String Generic string (enum) channel. resourceId, direction, commandToReact, pulseWidth
rollershutter RollerShutter Generic rollershutter channel. resourceId, direction, commandToReact, pulseWidth
rf-device-low-battery Switch RF device low battery warning. serialNumber
rf-device-signal-strength String RF device signal strength. serialNumber
push-button-trigger Trigger Push button trigger channel. Possible trigger events: PRESSED, RELEASED, SHORT_PRESS, LONG_PRESS and value as a duration in milliseconds. resourceId, longPressTime

Channel parameters:

Channel parameter Param Type Required Default value Description
resourceId Integer yes Resource Id in decimal format from project file.
direction Text no ReadWrite Direction of the channel (ReadWrite, WriteOnly, ReadOnly).
commandToReact String no Command to react. If not defined, channel react to all commands.
pulseWidth Integer no Pulse width in milliseconds. If defined, binding send pulse rather than command value to IHC controller.
inverted Boolean no false openHAB state is inverted compared to IHC output/input signal.
serialNumber Integer yes Serial number of RF device in decimal format.
longPressTime Integer yes 1000 Long press time in milliseconds.

There are several ways to find the correct resource id's:

  1. Find directly from your IHC / ELKO LS project file (.vis file).
  2. Via IHC / ELKO Visual application. Hold ctrl button from keyboard while mouse over the select item in Visual.
  3. Enable debug level from binding. Binding will then print basic resource ID from the project file, if loadProjectFile configuration variable is enabled.

The binding supports resource id's only in decimal format. Hexadecimal values (start with 0x prefix) need to be converted to decimal format. Conversion can be done e.g. via Calculator in Windows or Mac.

Resource id _0x3f4d14 is 0x3f4d14 in hexadecimal format, which is 4148500 in decimal format.

Mapping table between data types:

WSTimeValue DateTime datetime <resource_time id="_0x97db0d" …>

# Profiles

Binding provides IHC / ELKO specific ihc:pushbutton-to-command profile for push-button-trigger channels. This profile can be used to transforms trigger events to item commands without writing rules.

Profile support following configuration parameters:

Parameter Param Type Required Default value Description
short-press-command String no ON Define the command be send when short button press is detected.
long-press-command String no INCREASE Define the command be send when long button press is detected.
long-press-time Integer no 1000 Define the long button press time in milliseconds.
repeat-time Integer no 200 How often long button press command is send in milliseconds. If 0, long press command is sent only ones.
timeout Integer no 10000 Timeout for repeated long press command. Cancel long press command sending when this limit is exceeded.

Supported commands:

Command Supported Item Type
ON Switch
OFF Switch
STOP Player
PLAY Player
PAUSE Player
NEXT Player
UP Rollershutter
DOWN Rollershutter

All commands but TOGGLE are standard openHAB commands. When TOGGLE command is specified, profile will toggle switch item state. E.g. if item state has been OFF, profile will send ON command to item.


Dimmer test { channel="ihc:controller:elko:my_test_trigger"[profile="ihc:pushbutton-to-command", short-press-command="TOGGLE", long-press-command="INCREASE", long-press-time=1000, repeat-time=200] }

Will send TOGGLE (ON/OFF) command to Dimmer test item when short button press is detected (button press less than 1000ms) and send INCREASE commands as long button is pressed over 1000ms (200ms interval).
