KNX Utility

The KNX Utility application provides a graphical interface to configure a KNX I/O Server. Whenever a KNX I/O Server is defined in HSYCO, the KNX Utility will appear among the applications of the manager.

Open the application and select the KNX I/O Server to be configured in the select field in the top-right corner. If only one KNX I/O Server is defined it will be automatically selected.

Import an ETS4 project

To import an ETS4 project, upload the .knxproj file on HSYCO server, then click on the "Import" button at the bottom of the page and enter the file name (the “.knxproj” extension can be omitted).

ETS4 project import.

The checkbox option “keep defined virtual datapoints” is needed when updating an old KNX installation to an extended one and you need to retain the previously created virtual datapoints.

This procedure will create a datapoint for each group defined in the ETS project with the corresponding DPT type and the default attributes.

Datapoints

A datapoint is the equivalent of a group of the KNX framework. New datapoints can be added employing the import procedure described above or manually, by clicking on the "+" button in the "KNX Datapoints" tab. To modify the attributes of a datapoint click on the corresponding item in the list.

Attributes

Address

this is the KXN group address corresponding to this datapoint ranging from 0/0/1 to 31/7/255. It must be unique for each defined datapoint

DPT

the DPT type (ranging from 1 to 18) used to format the datapoint value

ID

the ID to assign to the corresponding datapoint of the KNX I/O Server. It can be any unique string without spaces

Description

a textual description of the datapoint. It will be visible in the Project Editor when configuring GUI objects

Priority

KNX priority to be used when sending frames to this group (low, normal or urgent)

Read

check this option if this group

Icon

attribute for DPT 1 datapoints. It specifies the icon to be used for button objects associated to this datapoint (the values correspond to the ones used in the devices list of systemtopo.txt)

Thumbnail

attribute for DPT 1 datapoints. It can be used to optionally associate an image or a camera to the datapoint. For images, use the filename of a file located in the www/img directory. To associate a camera, the “cam:<n>” format should be used, where <n> is the camera index starting from 1, based on the order of the camera list in the settings page

Virtual datapoints

KNX lights, dimmers, automations (e.g. blinds) and thermostats need a set of datapoints for control and feedback. It is possible to create a virtual datapoint that links these datapoints so to be treated as a single one which, in turn, can be directly associated to an object in the Web user interface.

Light

To add a "light" virtual datapoint select the “Lights” tab and click on the “+” button in the bottom bar.

Attributes

ID

an identification number for this datapoint. It will be used to compose the ID of the corresponding datapoint of the KNX I/O Server (e.g. if ID is set to 1 the corresponding datapoint will be 'light.1')

Description

a textual description of the datapoint. It will be visible in the Project Editor when configuring GUI objects

On value

specifies if the 'on' state for this light is represented by a value of '1' or '0'

Icon

It specifies the icon to be used for button objects associated to this datapoint (the values correspond to the ones used in the devices list of systemtopo.txt)

Thumbnail

It can be used to optionally associate an image or a camera to the datapoint. For images, use the filename of a file located in the www/img directory. To associate a camera, the “cam:<n>” format should be used, where <n> is the camera index starting from 1, based on the order of the camera list in the settings page

Feedback datapoint

datapoint representing the on/off feedback. It must be a DPT 1 datapoint

Command datapoint

datapoint to be addressed when sending on/off commands. It must be a DPT 1 datapoint

Dimmer

To add a "dimmer" virtual datapoint select the “Dimmers” tab and click on the “+” button in the bottom bar.

Attributes

ID

an identification number for this datapoint. It will be used to compose the ID of the corresponding datapoint of the KNX I/O Server (e.g. if ID is set to 1 the corresponding datapoint will be 'dimmer.1')

Description

a textual description of the datapoint. It will be visible in the Project Editor when configuring GUI objects

On value

specifies if the 'on' state for this light is represented by a value of '1' or '0'

Thumbnail

It can be used to optionally associate an image or a camera to the datapoint. For images, use the filename of a file located in the www/img directory. To associate a camera, the “cam:<n>” format should be used, where <n> is the camera index starting from 1, based on the order of the camera list in the settings page

Feedback datapoints:

Level

datapoint representing the dimming level feedback. It must be a DPT 5 datapoint

On/Off

datapoint representing the on/off feedback. It must be a DPT 1 datapoint

Command datapoints:

Level

datapoint to be addressed when sending a dimming level command. It must be a DPT 5 datapoint

On/Off

datapoint to be addressed when sending an on/off command. It must be a DPT 1 datapoint

Automation

To add an "automation" virtual datapoint select the “Automations” tab and click on the “+” button in the bottom bar.

Attributes

ID

an identification number for this datapoint. It will be used to compose the ID of the corresponding datapoint of the KNX I/O Server (e.g. if ID is set to 1 the corresponding datapoint will be 'autom.1')

Description

a textual description of the datapoint. It will be visible in the Project Editor when configuring GUI objects
