Hi all,
I re-setup everything two days ago through theses steps:
- Stopped Max Binding 2.3.0 using karaf => Status was “Resolved”
- Factory Reset of the Max Cube
- Paired all thermostat+ to Max Cube using MAX! Software on MacOSX
- Stopped MAX! Software on MacOSX
- Started Max Binding 2.3.0 using karaf => Status is “Active”
- Configured binding in exclusive mode, and update every 30sec.
Every works… ouch, no, everything workED, but all the configuration is lost again 
I wanted to follow @hmerk tutorial (HOWTO: Reflash MAX!Cube to CUL/CUNx and use with homegar and homematic binding) but at the moment I don’t want to use another solution than a OpenHAB stuff
To be continued…
