HOMEMATIC IP: Playground for some checklists

Connect HOMEMATIC IP GARAGE DOOR MODULE HmIP-MOD-TM

How to connect

online:

• unlearn the module from previous CCU, with reset to factory default
• disconnect the module
• rekeying: See below
• connect the module
• wait, it should connect

offline:

• unlearn the module from previous CCU, with reset to factory default
• disconnect the module
• enter Key and SGTIN. FIXME: should the - separators be entered or not? Raspberrymatic accepts both without error message
• connect the module
• wait, it should connect

The vendor doc says that instead of disconnect/connect, we should press the button shortly before starting learning mode. This does not seem to work reliably.

Meaning of LEDs

????? This is not documented by the vendor. At least I did not find it.

short red	guessing: learning failed?
short green	guessing: learning succedeed?

constant yellow	guessing: learning mode active

Reset to factory defaults

????? This is not documented by the vendor. At least I did not find it.

Rekeying

This seems to transfer a module from one CCU to another. How does it work? When is it needed? How long does it normally take?

Successful rekeying might look like this: :

Jan 6 01:19:05 de.eq3.cbcs.server.local.base.internal.HMIPTRXInitialResponseListener INFO  [Thread-6] Exchanging adapter from 3014F711A0001F58A9XXXXXX to 3014F711A061A7D3CXXXXXX ... 
Jan 6 01:19:04 de.eq3.cbcs.server.local.base.internal.HMIPTRXInitialResponseListener INFO  [Thread-6] No NWK, try to set address ... 
Jan 6 01:19:23 de.eq3.cbcs.server.local.base.internal.HMIPTRXInitialResponseListener INFO  [vert.x-eventloop-thread-1] Adapter exchange successful. 

Troubleshooting

Raspberry:

• the Pi 4 disturbs homematic communication. Try a USB extension cable for the Homematic USB transceiver

Offline:

• it seems that the key and the sgtin either do not have a checksum or that they are not checked by Raspberrymatic

Online:

• When using raspberrymatic:
  • activate ssh login
  • login with ssh
  • ping homematic.com
• is there a firewall rejecting outgoing connections to port 8443?

More questions

How are these files used by Raspberrymatic in this context? They seem to contain data of known modules.
