There are various types of plug-in modules out there that use either the old X10 standard or one of the more recent ones like ZWave. Has anybody seen this kind of thing in the NZ/AU market? Seems to be heaps of stuff available in the US and to a lesser extent in the UK, but I've yet to come across anything in this neck of the woods. There is a bit of vendor-specific stuff out there such as Clipsal C-Bus system, but it seems to be hideously expensive compared to standardised DIY type stuff available in the US.
ZWave/X10 appeals as a system can be gradually built up - this is a low to no-budget type of project! I've seen a few companies offering home automation solutions, but they invariably seem to be asking a fairly serious amount of money for high-end solutions based on proprietary systems, and are really aimed at non-technical people with money to burn.
Any and all comments welcome!
