I mostly want to do thzt because I want to be able to turn off heating and air conditioner remotely, but I would also like to have a master button to turn off all the lights when people live the apartment, a button to turn of lights on a path to the toilets in the bedroom and an alarm that automatically opens the shutters in the morning at the scheduled time (always found that waking up by sunlight is better)
Does anyone here have any recommendation of which devices I can control directly with something like a raspberry pi that's always on? I've read that Z-Wave's specifications avoid the Zigbee specifications pitfall that make them to vendor dependent..
