Hi,
So the code has evolved quite a lot over the last few days and may not be that relevant to my initial question but I wanted to share it here just in case anyone else would like to use any of it. Feel free to ask any questions and suggest amendments (its a bit over engineered).
Broadly speaking the purpose of the code is to do three things:
1. Turn on the lights when motion is detected (setting a count down timer)
2. Allow for different scenes to be executed at different times of the day
3. Reduce the countdown timer of other rooms in the house (on the basis that if you are in the living room, you probably aren't in the conservatory) This bit probably needs a bit more thought and could be cleverer
In addition to this there are three general categories of activation:
1. Motion detected when we are out
2. Motion detected when we are in and its dark
3. Motion detected when we are in, its dark and nightmode is on (this is a dummy switch to indicate that we are in bed).
In situations 1 and 3 the activated scene is hard coded, in the 2 situation the scene is read from a variable. The additional benefit of the variable is that I'm able to stop the motion sensors adjusting the scenes by having a 'none' scene. This means that if I want to show off my hue lights to visitors from the phone app or make use of scenes not in domoticz I dont have domoticz fighting me.
In addition to the code below there are two other scripts - one that counts down the countdown variables, and one that chnages the scene variable depending on time of day.
Thanks again for your help.

can not have it all... the likelihood that that happens is very very small 
I probably made some errors (timedate function, you probably can't just type sunset+1hour 
, dimmer level
