There actually is a big difference. The $95.00 pro switch does not require polling. They send data to the controller when there is a change in state at the switch. They also come with a ten year warranty instead of the 5 year. They are also based on the 2nd generation chipset which uses less power (an insignificant amount). Still, I would rather poll my devices anyway for 50+ dollars. Besides I don't even touch light switches in my house, that is the purpose of automation. Everything is controlled by my computer and motion detectors and lot's of programming. Who would want to use the switch anyway?
