Actually, you don't need a switch that transmits its address to do this. The Leviton discontinued "red line" and their newer "green line" X10 switches will do exactly what you want. They remember the last dimmer setting, and ramp up to that when turned on. They can also be sent a pre-set dim command so they will turn on at whatever brightness level you want. Their older "red line" switches have worked flawlessly for us since we built this house. They do require a neutral though.
