Velux Integra Roof Windows

[Nad]

Hi all,

Just wondering if anyone has looked into how to control these roof windows via Cortex? I'm guessing this is going to be another item that will need to be done via the API.
It looks like they seem to come with their own remote control and does offer the good old wall switch which would be easy to integrate.

Thanks,
Nad

Just found that they do have an interface unit called the KLF 050 which they seem to keep quite well hidden. I've found it for sale in some European sites but not much is mentioned in the UK. It would have been nice if the had a control port that you could just plug stuff into but i guess that's hoping for a bit too much in this day and age of wireless everything

This is the only PDF I've found for it ...

not much detail available - for our motorised beds, we wired in-parallel with the remote control's switches ...

one-way of course, no feedback, 'though we may yet add our own reed-switches ...

is the motor-unit accessible, for wiring into it, maybe ??

I'm planning to hack the ceiling fan remote to control them but unfortunately the standard Velux controller is a fancy touch pad unit.
I really like your idea about the reed switches for the feed back circuit, didn't even really think about that.

I don't know if the motor unit is accessible as I haven't got our 1st window yet. Should get my hands on one in a few weeks time.

Thanks,
Nad

Yes it looks like the wall switch interface could be the simple solution and Cortex does have a dedicated object for managing that kind of appliance (using relays in place of the buttons). If Velux are releasing a web based REST API for their stuff then Cortex will pretty soon be able to communicate via that route (spoilers ;-) ), though the proof will be in the specifics..

our bed's remote was wired to the motor-unit, so all we had to do was take the remote apart to decipher how the wires (few) were connected to the various button switches (many), then cut the cable & reconnect the two ends via Idratek relays ...

so, easier than with the wireless Velux touch-panel - OTOH, their receiver has to interface with their motor-unit in some way, and page two here seems to show the receiver unit wired to the motor-unit ... :

so, maybe the same trick could be applied in your case, too ... ?

That's a good point Chris. If the receiver unit is not integral then there may well be access to the motors and perhaps even feedback. On the other hand one might have to be careful to check that the motor control in the receiver is not doing something a bit more sophisticated than simply on/off, e.g if doing current sensing to check for stall in the receiver electronics rather than this being in the window. I suppose if it has been a simple add on evolution from older mechanical switches you'd think it would be the latter.
