Homegear supports EnOcean’s Rolling Code encryption. To enable it, set the configuration parameter
true, e. g. by executing on the console:
homegear -e rc '$hg->putParamset(<Peer ID>, 0, array("ENCRYPTION" => true));'
Then send a teach-in packet from the device. Please consult the device’s manual on how to do that. After the packet has been sent, the Homegear log should show a line like:
Module EnOcean: Info: Encryption was setup successfully. Encryption type: 3, CMAC size: 3 bytes, Rolling Code size: 2 bytes, Rolling Code: 0xED3C, Key: AE7B242C037FE6F098C8AEAE04CF1F5F
Now encryption is enabled.
