-    If you have defined a &lt;condition&gt; and this condition is false if the switchingtime has reached, no command will executed.<br>
-    An other case is to define an own perl command with &lt;command&gt;.
+    If you have defined a &lt;condition&gt;, this condition will be evaluated in the daily evaluation of the switching times. If false, no switching times will be set for this day. To force a re-evaluation, you may e.g. use the "enable" or "WDT_Params" commands<br>
