Velux electric windows come with their own remote control device, it’s very good and gives you granular control of each window, I’ve installed four windows. Velux call this range Integra and it uses the io-homecontrol protocol.
For my home intelligence/automation system I use Fibaro’s Home Center 2 which uses the zwave protocol. Not all is lost though and you can interface the two, you do however need to get some extra kit.
Velux have a device called the KLF 100. It can be used for several functions but I’m using it as a interface. There is a catch however, and that is if you want to control all windows individually you’ll need a KLF 100 for each window. However if you want to open all windows and close all windows then one KLF 100 can do this.
Open up the box and the unit is quite large.
I’ll be installing this in the loft so not too much of a problem.
Remove the lid and you’re presented with a display and three pins for connecting external devices.
At this point for testing I connected up a switch.
By doing this you can test the functionality and setup the interface without adding the extra complexity of the Fibaro setup.
The next session details the setting up of the interface step by step.
Turn on the unit and the loading screen is displayed
Select the language
Select the function, in this case Interface
The default channel is 7
Set the Up Position and the Down Position. With the setting below the window will open fully and close fully when the up or down button is press
The next stage is to register the windows with the interface
As all the windows are already reinsured with the Velux Intregra unit they can be sent from the control unit to the interface at this point. Navigate though the menus and send the products.
Once the products have been imported, create a list and add all the windows that you want to control, all four in my case then save it
Finish off the setup and test
By pressing the toggle switch all the windows will open together or close together, unless the rain sensors on the windows have triggered
Adding the Fibaro relay in-between the switch and the KLF 100 allows the Fibaro Home Center 2 to operate the windows via zwave. Screen shot of the iPhone interface
The final solution will be mounted and boxed away, but this has worked for the testing.
Here is the full wiring diagram, enjoy.
