The User Interface Configuration Database

The systemtopo.txt file should list all the I/O Servers data points that you want to control directly from the user interface.

It also contains the names of the Wi-Fi location zones.

Several I/O Servers support a discovery mode, where all data points that are suitable for direct control from the user interface can be automatically added to the systemtopo.txt file. Refer to the Application Notes in order to configure the I/O Servers.

systemtopo.txt can be modified at any time; any change is applied within a few seconds without restarting HSYCO. Web pages are automatically reloaded after any change to systemtopo.txt.

The file format is quite simple, it is separated in sections containing the list of all the devices available in the system. For example:


k.light.14 : LIGHT ; LIGHT ; 
k.light.21 : LIGHT ; DIMMER ; DIMMER
k.autom.14 : AUTOM ; VSHUT ;

Every section starts with a line where the name of the section is within brackets, followed by the list of devices corresponding to every section. Every line starts with the id, which identifies every specific device, followed by “:” and the list of parameters separated by “;”.

The file is read ignoring blank lines and blanks within the lines which are not significant.

Any mistake in the file content will be shown in the log. In case of a general syntax error, the error message is:

systemtopo.txt Parser: Syntax Error, line: nnn

The number of the file line of the first mistake will always be shown.

Note In case of error the file is not fully interpreted, therefore the Web interface would not be able to work. The content of systemtopo.txt must be formally corrected to allow the correct execution of the Web Interface.

The individual sections can be omitted if empty.

A systemtopo.txt file which is completely empty is a correct file anyway.

Every section must appear only once in the file, repeating the header of an already defined section is an error.


Contains a line for each Access Point id listed in the LocationBases parameter in the configuration file hsyco.ini.

The format is:

id : <zone name>

that is, the id as listed in LocationBases, followed by “:” and the user friendly name of the zone. The friendly name is shown on the up right corner of the display, and it is mandatory.




This section contains a line for each I/O Server data point that is used in the Web interface, with the following format:

id : <function>; <type>; <img>; <options>; <description>

id is the data point ID, a point separated string with no spaces. See the Application Notes for data points’ formats.

The <function> field can assume the LIGHT or AUTOM values, according to the configuration of the actuator associated to the bus address. For actuators configured in interlocking mode, it must be set to AUTOM.

The <type> field defines the type of function of the command, for the Web interface. It can assume one of the following values:

STD, LIGHT, DIMMER, VSHUT, HSHUT, LOCK, ONOFF, SCENE, corresponding to the graphics shown below (the DIMMER type is not shown in the chart since it is the same as LIGHT, the only difference is that the horizontal bar assumes a different length according to the dimmer level, in 20% steps) when using the standard “blue” skin.

The <img> field is optional. The following line has therefore a valid format:


The <img> field can be used to associate an image or a camera to the device.

By clicking on the button or passing with the mouse in the button area the static image or the video of the camera will be shown in a small, 120x80 pixels pop-up next to the button.

For images, use the filename with extension, 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 as listed in the Cameras parameter in hsyco.ini.

The <options> field is also optional. It can assume the NOCLICK value to deactivate, on the Web interface, the possibility to change the status of the device.

The <description> field is an optional comment, not relevant for the correct execution of HSYCO, but shown in the Project Editor’s devices list.
