 Define a sequence of commands to control other machines.
 Numbers(s) are the node numbers, the command shall sent to.
 The commands 'on'/'off' are used for machines and other nodes.
-Offset is the time to the next line in seconds (0..999).
+Offset is the time to the next line in seconds (1..999).
 If endless is set, the Sequencer restarts again and again.
 The command '  ' does nothing, only consuming the offset time.
