Connecting Velux Active KIX 300

Yes, as I mentioned the KIX 300 has HomeKit support which I didn’t tried. Above Connecting Velux Active KIX 300 mentioned HomeKit simulators/bridges which probably work completely local.

The API I use is the cloud-based-Netatmo-like-API which is also used in the Velux APP.

And then again there is the KLF200 which has absolutely nothing to do with the KLX 200 (neither netatmo cloud nor homekit API)

Thanks for the clarifications, @nougad! I will certainly continue to follow this conversation.

Hi guys,

I see that Velux Active now supports Google Home / Assistant since few months ago.

I have configured it with my KIX300 and it works, it is still buggy, but I believe that they will fix this with future versions.

So, here is the question; does this mean that they opened some api? Would it be possible now to use this for OH-KIX300 binding?

This is wonderful! Thanks a lot @nougad for your work and @Polo for your help, I can now store the sensor values and build graphs :grinning:

@nougad here’s the traffic for windows:

Found a much better way of how to interact with KIX-300, the answer is HomeKit.
It has several advantages over the reverse engineered solution used by velux-cli:

  • easier to setup
  • future proof as it uses a standard protocol to interact with the KIX-300
  • works locally, no cloud
  • works with windows as well
  • get all values from sensors

So this is what I did:

  1. install https://github.com/jlusiardi/homekit_python#installation
  2. create pairing file
  3. run discovery (within the same network!)
  4. run pairing (you find the pairing code of the KIX-300 on the backside of the gateway) - use ``velux` as alias
  5. list accessories with python3 -m homekit.get_accessories -f pairing.json -a velux
  6. get characteristics or put characteristics

Basically it’s just following the instructions from the link above :wink:

Example how to open a window (11.10 is the characteristic id you get from list accessories):

python3 -m homekit.put_characteristic -f pairing.json -a velux -c 11.10 50

Have fun!

Hi Bernhard
I just implemented your homekit solution. It works perfectly!! Thanks so much!

Is there a nice way to link the python commands directly to openhab?

Kind regards
Jens

did you implemented an binding module?

Hi Rafael,
i just followed the steps described by Bernhard. The commands via console work fine so far.
But I’m not sure how to make items and things from the python commands.

Kind regards
Jens

hi,

i’ve created following protoype. (i didn’t test the UP/DOWN/STOP commands for the blinds, could be that they are inverted and that the stop command doesn’t work at all). Using a slider for the blinds works pretty well.

you need to adjust the id’s (e.g. 5.10) and the path to the paring file (this file need’s to be owned by the openhab user, (not the openhabian user))

hi all,

i did already something with openhub and it went so far so good.

But with this i have a problem in creating the “pairing file”.
what information are needed and where can i find it?

I followd the link and installed the homekit_pyton and i can discover the bridge.
But thats it…

thanks for support

chris

hi all,

i found a good step by step guide


no it is working perfect for me

thanks

I have extracted the client_id and client_secret from the VELUX active 1.5.0.7 APK using JADX. Those two information are returned by some methods, located all in the same class file.

# client_id: 5931426da127d981e76bdd3f
# client_secret: 6ae2d89d15e767ae5c56b456b452d319

How to get your oauth2 token?

$ curl --location --request POST 'https://app.velux-active.com/oauth2/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=password' \
--data-urlencode 'client_id=5931426da127d981e76bdd3f' \

--data-urlencode 'app_version=1108002' \
--data-urlencode 'user_prefix=velux'

Hi Hubert,

Thanks for extracting and sharing that. Now working for me. :slight_smile: To get token:

curl -d “grant_type=password&client_id=5931426da127d981e76bdd3f&client_secret=6ae2d89d15e767ae5c56b456b452d319&username=my@email.com&password=mypassw&user_prefix=velux” https://app.velux-active.com/oauth2/token

As documented here:

Did anyone succeed in setting state for Departure Switch (NXD)?

Tried:

curl -s -H “Content-Type: application/json; charset=utf-8” -H “Authorization: Bearer mytoken” -X POST -d “${JSON}” “https://app.velux-active.com/syncapi/v1/setstate

with $JSON set to:

“home”: {
“id”: “myhomeid”,
“modules”: [
{
“id”: “xx:xx:xx:xx:xx:xx”,
“locked”: true
}
]
}
}

But get this response:

{“error”:{“code”:21,“message”:“cannot set property locked for module xx:xx:xx:xx:xx:xx”}}

@nougad - I may have somehow missed it, but how do you create a request for locking or unlocking your home?

/Jacob

Hi. Thank you very much for all info present in this thread.

I was able to install and run as openhabian the Homekit python version suggested by Bernhard and to define Things/Items as suggested by Rafael.

When I run the command as openhab I get below error:

/usr/bin/python3: Error while finding module specification for ‘homekit.get_characteristic’ (ModuleNotFoundError: No module named ‘homekit’)

The same command executed by openhabian work smoothly.

Python modules owner and group looks fine.

I have tried to move Homekit python site-packages in PATH to /usr/lib/bin but without success.

I have googled the error but without success (I’m not a python programmer nor a linux/raspberry expert).

Could you please give me some suggestions?

Release = Raspbian GNU/Linux 10 (buster)
Kernel = Linux 5.10.11-v7+
Platform = Raspberry Pi 3 Model B Plus Rev 1.3

Thank you in advance for your help.
Pierpaolo

Hi again. I’m going to answer myself :slight_smile:

To install homekit for openhab user the command is: sudo -u openhab pip3 install --user homekit[IP]

Probably also this command should work but I have not tested it: pip3 install --system homekit[IP]

To be honest I’m not able to understand if this can create problems on the raspberry installation or if it is ok.

Bye.

Pierpaolo

I have created a small instruction to patch the APK file and get all required info to interact with windows and unlock your home.
The app is only required once to get the all the keys.

Btw:
I was able to generate and exchange all other keys via web API except for the HashSignKey which seems to be generated when the app connects directly to the gateway. I could log that exchange with wireshark (~9 requests and responses between app + local gateway) but data seems to be encoded/encrypted.

But having all the keys allows to create own APIs (eg Node-RED).

Maybe this is useful to some people, like everything here was for me.

Hi there, I have an OpenHAB setup with a KLF200 to control my windows and rollershutters. It works fine apart from the KLF 200 being a pain to work with (login via its own WI-FI only!). However, whenever I need to restart the OpenHAB service the KLF200 refuses any incoming connection and I have to keep unplugging it completely several times for long periods of time until it hopefully starts working agains. This seems totally random and sometimes takes days.
As this is not acceptable I was hoping the KLX300 could be a solution. Will there be a binding for OpenHAB eventually? I am also happy to tinker with copy-pasting code to make it work. Thanks!

Newer KLF200 devices work reliable only over LAN access. The internal WiFi access point should be disabled automatically 10 minutes after power connection. This has been added to the latest Pull Request documentation.
My setup is running fine for 2 month now.
