To take the last point first: Just created a new version to implement heating state / actuator state. Please feel free to test and report any errors/misbehaviour.
- odp0011: Retrieve heating state (set up as on/off switch, read only)
- odp0013: Retrieve heating actuator state (set up as a dimmer (0-100), read only)
Regarding logging, I am a bit uncertain as you are referring to syslog/console log, and here you will see the complete XMPP stream from your SysAp. And XMPP is mainly handled by an external library. Assume you are running OH from a PC or Mac? This information is not logged in regular OH logs.
