A HomeMatic CCU Addon implementing a xml request functionality as an interface to all homematic deviced available to a CCU device. This addon provides useful scripts that can be accessed via a HTTP request to a CCU device and allows to query and set all e.g. room- and devicetype names.

Supported CCU models


This addon can be added like a usual CCU addon package via the WebUI provided functionality by selecting "System-Konfiguration » Systemsteuerung » Zusatzsoftware", to upload the addon package as a tar.gz and the use »Installieren« to actually install the addon. After a restart of the CCU the xml-api interface can then be selected from the »Zusatzsoftware« tab in the CCU settings.

Security advice

The call to one of the API routines is without any authentication. If the HomeMatic control center can be reached via the Internet without special protection, this is a serious security risk!


After installation the XML-API should be avilable via the following URL call:


where [CCU_IP] corresponds to the IP address or name of your CCU device and [ScriptName] being one of the following tool scripts:

ScriptName Description / Parameters
devicelist.cgi             Lists all devices with their channels. Contains name, serial number, device types and ids.
show_internal=1 (outputs all internal channels also)
functionlist.cgi           Lists all functions with their channels.    
favoritelist.cgi           Lists all favorites and users.
show_datapoint (outputs also attribute datapoint_id and datapoint_type)
mastervalue.cgi             Returns one or more (1234,5678) devices with their names and values of their master values.
device_id=1234 (returns all master values of device)
requested_name=TEMPERATURE_COMFORT,TEMPERATURE_LOWERING (returns only master values for specified names)
mastervaluechange.cgi       Sets one or more (TEMPERATURE_LOWERING,TEMPERATURE_COMFORT) master values of one or more (1234,5678) devices.
device_id=1234 (sets master values of device)
name=TEMPERATURE_LOWERING (sets specified master value only)
value=17.0,22.5 (sets master values to specified values)
programlist.cgi             Lists all programs.
programactions.cgi change the Programactions active and visible
Parameter: programactions.cgi?program_id=1234&active=true&visible=true
protocol.cgi               Returns the system protocol.
clear=1 (clears the system protocol)
runprogram.cgi             Starts the specified program.
program_id=1234 (id of program to start)
roomlist.cgi               Lists all rooms with their channels.
rssilist.cgi Lists all devices with their signal strength.
scripterrors.cgi           Searches the last 10 lines of /var/log/messages for homematic-script errors and output these.
state.cgi                   Returns for single or multiple devices (1234,5678) the channels and their values.
device_id=1234 (id of the device to return values)
channel_id=5678 (id of the channel to return values)
datapoint_id=12839 (id of data to return only Value())
statelist.cgi               Lists all devices with channels and current values.
ise_id (id of devices to list values for)
show_internal=1 (also return internal attribute state)
statechange.cgi             Changes one or more channel states.
ise_id=1234,5678 (id of the channels)
new_value=0.20 (new value for channel state)
systemNotification.cgi     Returns the current system notifications
systemNotificationClear.cgi Clears all current clearable system notifications.
sysvarlist.cgi             Lists all system variable with values.
text=true (return current value of system variable in attribute value_text)
sysvar.cgi                 Returns single system variable with values.
ise_id=1234 (id of system variable)
version.cgi Outputs version of XML-API

All of these scripts, if called, generate a xml structured output that can then be used by third-party applications to display or modify certain information. All of these scripts rely on a ise_id device or channel identifier. You can get this ise_id for the needed datapoint by analysing the result of statelist.cgi. The id can be used in the following way:


This call, if executed with the right ise_id and IP adress would then set a dimmer to 20%.




  • implemented mastervalue query + change which can also handle HmIP devices.
  • fixed version output


  • fixed incorrect use of .Variable() on alarm type system variables.


  • add programactions.cgi for activ and visible Programactions


  • fixed bug in sysvar.cgi if called without any argument (ise_id) resulting in a SyntaxError in ReGa.

  • fixed a bug where .Timestamp() was incorrectly used in protocol.cgi.


  • Support to query and set master values via mastervalue.cgi and mastervaluechange.cgi
  • Fixed systemNotification.cgi to not use .AlDestMapDP() incorrectly.
