The "dark only" suggestion is useless since my motion sensors are outside the house where they can't "see" the lights.
As far as hard coding the override into the switch, I don't see why it would be a problem, since if you manually hit the switch to turn it on then you can manually hit the switch to turn it off (if you're relying on lack of motion to turn it back off then you would also be relying on motion to turn it on in the first place)... you won't necessarily have your motion sensor right under your light (I have some of these in my house and they have the sensor inside the wall switch - more reliable and simple than X10 wireless for that application, not to mention cheaper).
Why does everybody worry about a few cents extra cost per unit when it would actually make it useful and bring it up to standard with similar units from other companies? I'd be willing to pay extra... the reality is that the motion sensors and wall switches probably cost less than $1 to make. They've been riding that profit margin for YEARS without making any major improvements (while manufacturing costs sunk and they recouped their development cost)... I mean you can't even adjust the sensitivity or range or get sensors with different fields of view (wide, narrow, etc.) like you can get with wired sensors on other brands. You can't make the local wall switch keep the light on like you can do with other units that either have a direct mechanical override switch for on (not just off) or let you flip the switch off and back on to make the light stay on (like most wired outdoor security lights).
I was really hoping the engineers or somebody at the company might read these comments and consider them as a way to improve their product and/or customer satisfaction rather than getting a bunch of responses like "but it would add cost" or "it could be tricky or cause problems so we shouldn't even try". We'd still be driving Model Ts if Chevrolet hadn't developed a competing product that had features customers wanted, and Ford would be gone if they hadn't responded with new products and features, the same will happen to X10 if they continue to sit and let the evolving pile of products found at Home Depot take over.
