Ventilation remote support KNX protocol over RF
Maarten

Hi as I'm preparing my house for my homey I have the option to install a Q-Stream Picto 12 Volt Ventilation system with a optional remote. That's nice, but I would rather have homey do the remote function. I called the company Buva but they couldn't give me more info about the technology used.
I found out it uses RF with the KNX protocol. Any idea if this is gonna be supported? It would be really nice if I don't even have to buy the remote. Because I think the communication is wireless by default. Thank you!

The KNX BAOS binary protocol typically precludes the development of client applications that run in a web browser. For this reason, access to the object server is now possible via the new KNX BAOS Web Services, based on HTTP and Java Script Object Notation (JSON).

has used the same chip as Homey uses (the CC1101) to sniff stuff from his Siemens KNX setup. He also posted the config he used to achieve this (taken from his "cc1101.cpp"):
Now, I am by no means a developer, but I can write some basic stuff when I need to. So I moved over to this page here:
https://developers.athom.com/library/signals/rf/
At first I was hopeful, a lot or parameters seemed to match the ".cpp" file. But when it came to modulation, it said:
However, the Homey dev documentation states:
"The table below shows the radio configuration used by the 433 MHz and 868 MHz receivers. These values cannot be changed by a developer.
I'm not really that familier with this kind of hardware, but my gut feeling is telling me that that might be a showstopper. Can anyone who actually knows what they're doing comment on this? Or point me in the right direction to start developing an app for KNX?
Thanks!
I'm interested in this function as well. Do you have any update? Or still waiting on response from developers?
