Velux Binding

This binding integrates the Velux devices with help of a special gateway, the Velux Bridge KLF200. The Velux Binding interacts via the Velux Bridge with the Velux devices like window openers, shutters and others.

For details about the feature, see the following website Velux

Binding Configuration

The binding can be configured by parameters in the global configuration file openhab.cfg.

Property Default Required Description
bridgeIPAddress Yes Hostname or address for accessing the Velux Bridge.
bridgeTCPPort 80 No TCP port for accessing the Velux Bridge.
bridgePassword velux123 No Password for authentication against the Velux Bridge.
timeoutMsecs 2000 No Initial Connection timeout in milliseconds
retries 6 No Number of retries during I/O

Advise: if you see a significant number of messages per day like

 communicate(): socket I/O failed continuously (x times).

please increase the parameters retries or/and timeoutMsecs.

For your convenience you'll see a log entry for the recognized configuration within the log file i.e.

2018-07-23 20:40:24.746 [INFO ] [.b.velux.internal.VeluxBinding] - veluxConfig[bridgeIPAddress=,bridgeTCPPort=80,bridgePassword=********,timeoutMsecs=2000,retries=10]


Unfortunately there is no way to discover the Velux bridge within the local network. Be aware that all Velux scenes have to be added to the local Velux Bridge configuration as described in the Velux setup procedure.

Item Configuration

The Items of a Velux Bridge consists in general of a pair of mastertype and subtype definition. In the appropriate items file, i.e. velux.items, this looks like

{ velux="thing=<Mastertype>;channel=<Subtype>" }

Optionally the subtype is enhanced with parameters like the appropriate name of the scene.

{ velux="thing=<Mastertype>;channel=<Subtype>#<Parameter>" }
Mastertype Description
bridge The Velux KLF200 represents a gateway to all Velux devices.
scene Named ordered set of product states which can be activated for execution.


Subtype Item Type Description Mastertype Parameter
action Switch Activates a set of predefined product settings scene required
silentMode Switch Modification of the silent mode of the defined product settings scene required
status String Current Bridge State bridge N/A
doDetection Switch Start of the product detection mode bridge N/A
firmware String Software version of the Bridge bridge N/A
ipAddress String IP address of the Bridge bridge N/A
subnetMask String IP subnetmask of the Bridge bridge N/A
defaultGW String IP address of the Default Gateway of the Bridge bridge N/A
DHCP Switch Flag whether automatic IP configuration is enabled bridge N/A
WLANSSID String Name of the wireless network bridge N/A
WLANPassword String WLAN Authentication Password bridge N/A
products String List of all recognized products bridge N/A
scenes String List of all defined scenes bridge N/A
check String Checks of current item configuratio bridge N/A
shutter Rollershutter Virtual rollershutter as combination of different scenes bridge required

Subtype Parameters

In case of the scene-related subtypes, action and silentMode, the spezification of the related scene as parameters is necessary;

{ velux="thing=scene;channel=<Subtype>#<Parameter>" }

The subtype shutter requires an even pair of parameters, each defining the shutter level and the related scene:

{ velux="thing=brigde;channel=shutter#<Level1>,<Scene1>,<Level2>,<Scene2>" }

Virtual shutter

As the bridge does not support a real rollershutter interaction, this binding provides a virtual rollershutter consisting of different scenes which set a specific shutter level. Therefore the item definition contains multiple pairs of rollershutter levels each followed by a scene name, which leads to this setting.

For those who are interested in more detailed insight of the processing of this binding, a deeper look can be achieved by increased loglevel.

During startup of normal operations, there should be only some few messages within the logfile, like:

[INFO ] [.b.velux.internal.VeluxBinding] - Velux refresh interval is 3600000 seconds.
[INFO ] [.service.AbstractActiveService] - velux Refresh Service has been started
[INFO ] [.b.velux.internal.VeluxBinding] - veluxConfig[bridgeIPAddress=,bridgeTCPPort=80,bridgePassword=********,timeoutMsecs=2000,retries=6]

Supported/Tested Firmware Revisions

The Velux Bridge in API version One (firmware version 0.1.1.*) allows to activate a set of predefined actions, so called scenes. Therefore beside the bridge, only one main thing exists, the scene element. Unfortunately even the current firmware version does not include enhancements on this fact.

Firmware revision Release date Description 2016-06-01 Default factory shipping revision. 2017-07-01 N/A 2017-12-14 N/A

Unknown Velux devices

All known Velux devices can be handled by this binding. However, there might be some new ones which will be reported within the logfiles.Therefore, error messages like the one below should be reported to the maintainers so that the new Velux device type can be incorporated."

[ERROR] [g.velux.things.VeluxProductReference] - PLEASE REPORT THIS TO MAINTAINER: VeluxProductReference(3) has found an unregistered ProductTypeId.
