HOMEMATIC IP: Playground for some checklists

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.

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

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:

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?

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