+       Set the OWServer device which should be used for sending and receiving data 	 
+       for this OWDevice. Note: Upon startup fhem assigns each OWDevice 	 
+       to the last previously defined OWServer. Thus it is best if you define OWServer 	 
+       and OWDevices in blocks: first define the first OWServer and the OWDevices that 	 
+       belong to it, then continue with the next OWServer and the attached OWDevices, and so on.

     <li>trimvalues: removes leading and trailing whitespace from readings. Default is 1 (on).</li>
     <li>polls: a comma-separated list of readings to poll. This supersedes the list of default readings to poll.</li>
     <li>interfaces: supersedes the interfaces exposed by that device.</li>
