maybe thats just it one would think it shouldnt matter but perhaps i need a secondary source of power - rather than using one source in parallel, for the lights and sensor...
I was thinking that perhaps the sensor doesn't put out a proper sinusoidal wave that the SSR recognizes - and hence thats why it just hums and flickers.. i will give your suggestion a try though..
As for the other respondant:

yes its pretty far - ive toyed with the idea, but it's a bay door so a wall occupancy sensor would not work... but thank you for the suggestion
