[SOLVED] A switch to turn on/ off rules

Nope, you don’t connect the roller shutter channel to the newly created item Rolladensteuerung_AnAus_Switch.state. This item is a virtual item (for more info: Design Pattern: Unbound Item (aka Virtual Item)) to prevent the rule from running. It must not be connected to a channel.

your rule should be like:

rule “Rolladen hoch bei Sonnenaufgang”
when
    Channel ‘astro:sun:local:civilDawn#event’ triggered START
then
    if (Rolladensteuerung_AnAus_Switch.state == OFF) return;
    
    Rolladen_ALLE.sendCommand(1);
    Rolladen_Hauswirtschaftsraum_BlindsControl.sendCommand(100)
end
