Home control unit

[iobrokerneu]

Hello,
is there a possibility to add the new Homematic IP central unit as well? This is about the Home Control Unit.

Best regards,
Sascha.

I am not able to make any tests or reverse engineering because I don't own the device. I have no idea how and whether the connection works at all.

If somebody could do some research and tell me what to do, I could implement it.

I tried hmip_generate_auth_token.py with my HCU and it does not work.

1. connectionRequest REST request seems to work
   Response Code: 200 Date: Sat, 30 Nov 2024 19:34:11 GMT Content-Length: 0 Connection: keep-alive Server: TRA Tra-Request: d71fc58e746e9232f7ad3b3c620779ee Tra-Gateway: rewz Tra-Location: DE Tra-Version: 1.0

2. requestAuthToken does always return INVALID REQUEST, even after pressing the button on the HCU

3. The button on the HCU seems to have a different behavior: when you press the button the App shows the message "Remote access enabled for 5 minutes, to create new users"

Any tips what I can test or how I can capture/decrypt the communication ?

I can propose Charles proxy:

• install charles proxy
• prepare SSL decryption https://www.charlesproxy.com/documentation/using-charles/ssl-certificates/ (works best on iOs, Andrroid s a it difficult)
• setup as proxy for the Wifi connection
• verify that it works by e.g. getting a webpage and if you see GET/POST requests in proxy then all good ... if you only see "CONNECT" then ssl do not work and needs to get fixed
• start the Homematic app and do a "pairing" ... look at whats there and if you like provide the charles file (saved session)

I would also be interested in seeing it :-)

I have created a PR in HomeAssistant (home-assistant/core#132537) to bump homematicip to latest version. I think you should be able to use the HCU after that in HomeAssistant.

#543

@hahn-th the PR fixes the token generation only to make hmip_generate_auth_token.py work !
There are some more updates needed for the hm_cli.py to work (I'm just about to add those)
I also missed to remove sys.path settings from hmip_generate_auth_token.py which I used for debugging on my system.

[hahn-th]

Okay. Tell me when you're ready.
Are the lots of changes necessary?

[dietzm]

I just created the new PR. I added the accesspoint-id to all headers and created a new device type ACCESS_POINT.
My tests using hm_cli and pytest worked fine.
Please note that I can not test with the old HAP accesspoint anymore. I hope that the additional header does not impact it.

[dietzm]

hm, some aio tests seem to fail.

[dietzm]

ok, all done

if someone could briefly explain how to install the new version in HA, that would be really great :)
