You need some microcontrolled switches, some microcontrolled relays and microcontrolled dimmers (they go near the circuit breaker panel) , some low voltage (12v/24v/35v) power modules to power the microcontrollers inside the switches and leds, in the switches, and to give a little bit of power for switching the relays and dimmers on/off. You need the TPS Electrical wire (125v-240v AC) to go from the light fittings back to the computer controlled relays/dimmers. You will also need some RS485 (see above for defn) wire for multi-drop chaining the switches.
