}

rules( KAKU2 is set to ON twice for debugging purpose. Log will show exact time )

rule "Zonsondergang: Licht achter aanzetten 30 MINUTEN VOOR ZONSONDERGANG"
when
    Channel "astro:sun:SchinMin30:set#event" triggered START
then
    RFX_Kaku2.sendCommand(ON)
    logInfo("RFXCOM", "(Licht achterkamer) KAKU2 Gaat AAN 30 minuten voor zonsondergang" )
end

rule "Zonsondergang: Licht achter aanzetten ZONSONDERGANG"
when
    Channel "astro:sun:home:set#event" triggered START
then
    RFX_Kaku2.sendCommand(ON)
    logInfo("RFXCOM", "(Licht achterkamer) KAKU2 Gaat AAN op zonsondergang" )
end
