This is the one that caused me grief big time...;-(... So i had to remove
the timing function of the Lounge lights.......

Not sure if this is the best way to implement this sort of thing.......
But what i have done (and im just about to test)...is when the counter
reaches zero start ramping the lights off over 1 minute period and start a
30 second timer at the same time....When the timer rings it checks the
vacancy sensor status and if on either thru pir probe or ir probe
activation
ramps the lights back up to 100%...???

Like this idea also just not sure how to implement it.......

Thanks for the pointers
