I installed an Ubuntu >>Ubuntu 18.04 LTS <<(in VMware) with OpenHAB 2.3.0 and would like to get Homematic running with OpenHAB.
CCu2 with firmware: 2.35.15 is working together with the temperature sensor (HM-WDS40-TH-I-2). I tested IOBrocker and was able to create nice charts.
Now I am trying to get the CCU2 working with an temperature sensor in OpenHAB (switched off IO Broker)
For Testing purpose I connected my SONOS with OpenHAB and tested the functionality.
Surprise – it worked immediately!
Afterwards I installed the Homematic binding. But the status is still offline. After some googling I found a way to read the logs:
845 [ERROR] [est.core.internal.thing.ThingResource] - Exception during HTTP PUT request for update config at 'things/homematic:bridge:OEQ0456190/config'
java.lang.NullPointerException: null
Help and hints appreciated
Config screen attached
