Waking up rule | Homeautomation

In the morning I like a relaxing wake up. The music starts playing and gradually increase in volume as does the lighting. This is how ny rule to do this looks like:


rule "Wekker Aan"
    when
       Time cron "0 0 7 ? * MON-FRI"
    then
     SonosPlay1SlaapkamerIvo_Volume.sendCommand (10)
     SonosPlay1SlaapkamerIvo_MediaControl.sendCommand (PLAY)
     HueAmbianceCeiling1_Brightness.sendCommand (5)
     HueAmbianceCeiling1_ColorTemperature.sendCommand (100)
end
rule "Licht Aan"
    when
     Time cron "0 1 7 ? * MON-FRI"
    then
     SonosPlay1SlaapkamerIvo_Volume.sendCommand (20)
     HueAmbianceCeiling1_Brightness.sendCommand (10)
end

rule "Licht Change"
    when
     Time cron "0 2 7 ? * MON-FRI"
    then
     SonosPlay1SlaapkamerIvo_Volume.sendCommand (50)
     HueAmbianceCeiling1_Brightness.sendCommand (20)
end

rule "Licht Aan, geluid uit"
    when
     Time cron "0 5 7 ? * MON-FRI"
    then
     SonosPlay1SlaapkamerIvo_MediaControl.sendCommand (PAUSE)
     HueAmbianceCeiling1_Brightness.sendCommand (75)

end
