 This node supports the following modes:
 
-* `group code + Device` - For devices without family code. The group code is either an binary string with length 5 or a numeric value (1-4) and could be set in field <b>Group</b> or <b>msg.group</b>. The switch/device could be set in field <b>Device</b> or <b>msg.device</b> (value [ABCD] (in this case Field Device must be set to "msg.device").  The Switchposition could be set in field <b>Switch Position</b> or in <b>msg.payload</b>. In this case the value 0 means off and the value 1 means on.</li>
-* `Family + Group code + Device` -For devices with family code. The Family code must be one of the chars [abcdef] and could be set in field <b>Family</b> or <b>msg.family</b>. The group code is numeric and must be one of the values [1234] and could be set in field <b>Group</b> or <b>msg.group</b>. The switch/device could be set in field <b>Device</b> or <b>msg.device</b> (value [ABCD] (in this case Field Device must be set to "msg.device"). The Switchposition could be set in field <b>Switch Position</b> or in <b>msg.payload</b>. In this case the value 0 means off and the value 1 means on.</li>
-* `Channel + Device (Tristate)` For devices with tristate code like micro-electric AS 73 witch is also sold as REV Telecontrol in Germany (Version with house code with 6 DIP switches). The Channel code must be a binary string with 0=off and 1=on and could be set in field <b>Channel</b> or <b>msg.channel</b> (in this case Field Channel must be empty). The switch/device could be set in field <b>Device</b> or <b>msg.device</b> (value [ABCD] (in this case Field Device must be set to "msg.device"). The Switchposition could be set in field <b>Switch Position</b> or in <b>msg.payload</b>. In this case the value 0 means off and the value 1 means on.</li>
-* `Tristate String ` Send a tristate string. The String could be set in field <b>systemcode</b> or <b>msg.payload</b>. Only the chars 0,1,F and S without any blanks are alowed.</li>
-* `Binary String` Send a binary string. The String could be set in field <b>systemcode</b> or <b>msg.payload</b>. Only the chars 0 and 1 without any blanks are alowed.</li>
