I had a choice of two threads to post this reply and selected this one as it was the first (the second being Lightwave signal range in UK)
I have found a non-scripting way round the double button press issue on the LightwaveRF Mood Switch i.e. second and subsequent same button presses not being detected.
As recommended by durosity earlier in this thread, set-up a trigger to detect a device Last Updated change:
LightwaveRF Mood Switch > Last Updated > Has Any Change.
Then add a Condition: 'If device' > '< YOUR LIGHTWAVERF MOOD SWITCH NAME>' > 'Command' > 'is equal to' > '<YOUR MOOD SELECTION> e.g. Mood 3'
Then specify the action for selected Mood.
Now multiple button presses on the same button will work and no scripting involved
