Don't use bluetooth for home automation (it is simply to big and complicated). ZigBee is a new coming standard and very simple protocol for things like that. At client/slave side you only need the horsepower of a 8051. Bluetooth reuires at least a ARM controller ;-) (ZigBee is very new and there are no chips available yet).
Some examples: a bluetooth device needs approx. 3 seconds to get logged in the bluetooth network. A very long time for a light switch ;-). Zigbee requires 30ms for this. A bluetooth chip needs much power (mobile phone operation, you need to regularly recharge it). The Zigbee parts are deigned to run 2 years from battery (hopefully :-).
