I have a problem with my fresh installation of openHAB 3.0.1 and the Homematic Binding.
I have installed the binding and a thing for the Homematic bridge appears in the things inbox (eQ3-HmIP-CCU3-App, homematic:bridge). However, if I want to add the bridge as a thing, openHAB just outputs the message “Error during thing creation: Server Error”. openHAB does not produce any log messages when the error occurs (log level for the Homematic binding is set to TRACE).
I am running the following configuration:
- openHAB Hardware: Raspberry Pi 4 Model B Rev 1.4
- openHAB OS: openHABian 3.0.1 - Release Build
- openHAB Java Runtime Environment: openjdk 11.0.10 2021-01-19 LTS
- Homematic: RaspberryMatic 18.104.22.16891130 connected to a Homematic LAN Gateway
In RaspberryMatic I enabled full access for Homematic XML-RPC API and Remote Homematic-Script API and I disabled authentication as stated in the Homematic add-on configuration guide found in Homematic - Bindings | openHAB. There is no firewall active on openHABian.
I tried debugging using the following commands in the openHAB console:
stop org.openhab.binding.homematic log:set TRACE org.openhab.binding.homematic start org.openhab.binding.homematic
After the start command the following log messages are produced:
18:48:03.188 [DEBUG] [nternal.discovery.CcuDiscoveryService] - Starting Homematic CCU discovery scan 18:48:03.341 [TRACE] [nternal.discovery.CcuDiscoveryService] - Eq3UdpResponse: Eq3UdpResponse[deviceTypeId=eQ3-HmIP-CCU3-App,serialNumber=] 18:48:03.343 [DEBUG] [nternal.discovery.CcuDiscoveryService] - Discovered a CCU gateway with serial number '' 18:48:03.492 [TRACE] [nternal.discovery.CcuDiscoveryService] - Eq3UdpResponse: Eq3UdpResponse[deviceTypeId=eQ3-HM-LGW-App,serialNumber=KEQxxxxxxx]
I’d appreciate any help. I have no idea where to continue searching for the problem.
