Does anybody know how I can control my windows and blinds supplied by Velux they have rf remote controls but I can not find the protocol or commands anywhere.
Is there a way of capturing a command when i operate the remote and then sending that command when I want then to operate?
Sure this would be of use for other products?
Pete
I think this depends on which technology the windows / blinds are using. Mine are using io-homecontrol, and in their FAQ it says, that the communication is encrypted. So even with a RF-device attachted to something like a Raspberry it won’t be easy to control anything. In my personal opinion it would make more sense to take apart the remote controls and just control them via GPIO with a Raspberry.
However, if more modern models use something different for control, then there may be less destructive ways to include your windows in your home automation.
I am sure mine are the same as yours i have just ordered a broadlink as i think i can teach it the command and then control it from HA if ever I get my head round setting it up.
I have 12 windows and blinds so makes it very difficult to control via a hardware solution I am told there is a BMS interface available so waiting for that information to come through
If i get a solution will let you know.
There is no cheap solution at the moment. Except of hacking the remote controls like danielperna84 said.
But if you have access to the cables of the windows and blinds (attached to the KUX 110) you can directly use 24V to control them with a z-wave relay.
I just stumbled upon this: https://github.com/home-assistant/home-assistant/pull/8203
The product description Programmierbares VELUX INTEGRA® Interface (KLF 200) says its compatible to io-homecontrol, so maybe this device would actually be the solution.
I have just ordered one so we will see the HA site does not give much clue to a newbie like me how I would talk with it but it will be fun finding out
The documentation could indeed benefit from some more details. But I guess if you have such a device and know your way around HASS it won’t be hard to figure it out. If you succeed in getting this up in running it would be very nice if you could extend the documentation to include an example. 
Hi Pete, any news? I am considering to order a klf 200 too and looking for some feedbacks!
It’s on a 7 to 10 day lead time and then I will need some time to play. But will report back if I get it working
It will resolve one problem I have of the remote controls not covering the whole house as it’s a repeater
I am going to try and get a conversation going with the w otter of the HA addin
I sure will - if I get it to work be nice to give something back
Hi Pete, any news? In the meanwhile I bought klf-200ww too.
I received it today by my new house is a bit in delay (no electricity yet!) thus can’t play with it
Jan, did you really succeed to control a Velux blind directly with a z-wave relay?
I have had no time to play with this but will do soon
Did it work @Pete69?
I just took a DML integra blind apart to figure out if it does what I think that it does. I was trying to get a KLF050 to talk to the blind directly, but I suspect I need a KLF or KUX to drive it after all. I see no antenna system on the blind. Is Velux sending the commands over the 24V wires?
is the KLF 200 working in HA ?
yes it does but limited to the scenes created within KLF200 and exported to HA
Hi,
I also have 3 Velux Integra Windows including 3 Blinds.
Currently I am using a KLR200 to control the windows and blinds but somehow I want to bring more logic into the solution (closing blinds when temperature of my Wunderground Station is abve a defined threshold).
If I got it correct I would need 2x KLF 200 as one system can only control 5 products? All three windows are independent…
What about Somfy and Tahoma or Connexoon?

Hi Johannes
I have your same setup and 1 KLF200 has no problem to cope with it.
I think you need just 1 then
Hi,
Excuse me my stupid questions, but I am new in this topics:
I have 3 rooms with roof-window. I want to install 3 cheap wireless temperature seonsors in each room. Then I want to use the temperature and solar sensor from my wunderground weatherstation.
Depending on the inside/outside temperature and the solar status I want to open/close the windows and blinds.
I think this should be possible?
Br,
Johannes
