I’ve been a fan of Ubiquiti Networks products for a while and they’ve recently expanded their mFi range of home/business automation stuff. These “mFi In-Wall Manageable Devices” are wi-fi enabled switches and power outlets that can be centrally managed. Turn em all off/on, log power consumption, set timers and remotely manage it all. You can even dim lights by sliding your finger up or down the switch to adjust the light level. A whole house of these would be awesome. Hopefully they release these certified for use in Australia soon. No word on pricing, but Ubiquiti are pretty reasonable pricing wise.
