240V –> switchboard –> switch –> light
CBUS
240V –> switchboard –> CBUS relay –> switches/button or dimmer –> lights
CAT5, but not Ethernet
Motorola HC05 (a few years ago)
32.5V DC to power light switched 4KHz
infrared sensor, light sensors, serial interface, Ethernet interface
buttons assigned to group numbers output channels assigned to groups
long press, increase brightness short press, decrease brightness
all off button
1 light = switch1 or switch2 1 light = switch1 and switch2
ASCII serial commands
serial sniffing send stuff, receive stuff Intel hex dump, looks similar address data checksum
information on clips website
cost to get started
$3000 for first switch
standard house with wiring, $5000 for system to be installed. ceiling fans, power points used to control Christmas tree Dynalite, similar system, open protocol X10??? no intelligence, just the protocol X10 sensors are expensive Need Australian models, are legal in Australia. X10 is slower
open hardware project???
$30 per cheap switch $100 per light switch
soft dimmer, increase brightness gradually, increase globe life relays noisy, but required for fluorescent lights
Oscar, extension on alarm control system, not very good
heating/cooling, yes, if via 240V interface
turn lights on/off from the comfort of your mobile phone
reliability single point of failure, switch board can have two switch boards hit by lightning could cause problems two wires
