+        In case the disable condition becomes true while a RandomTimer is already <b>running</b>, by default the same action is executed as when stoptime is reached (see keepDeviceAlive attribute). Setting the <b>disableCondCmd</b> attribute changes this as follows: "none" will lead to no action, "offCmd" means "use off command", "onCmd" will lead to execution of the "on command". Delete the attribute to get back to default behaviour.<br>
