Hacking Home Automation Systems Through Power Lines

Quoted from Hackaday.com

As home automation becomes more and more popular, hackers and security experts alike are turning their attention to these systems, to see just how (in)secure they are.

This week at DefCon, a pair of researchers demonstrated just how vulnerable home automation systems can be. Carrying out their research independently, [Kennedy] and [Rob Simon] came to the same conclusion – that manufacturers of this immature technology have barely spent any time or resources properly securing their wares.

The researchers built tools that focus on the X10 line of home automation products, but they also looked at ZWave, another commonly used protocol for home automation communications. They found that ZWare-based devices encrypted their conversations, but that the initial key exchange was done in the open, allowing any interested 3rd party to intercept the keys and decrypt the communications.

While you might initially assume that attacks are limited to the power lines within a single house, [Kennedy] says that the signals leak well beyond the confines of your home, and that he was able to intercept communications from 15 distinct systems in his neighborhood without leaving his house.

Can’t imagine how someone disturbing your private time while you’re enjoying your hot bath? think again. have a nice weekend.

Wirelessly Automate Your Home

I’ve stumbled across this quite simple idea of home automation using Wifi. [Mrx23] combined OpenWRT, a microcontroller, and a set of RF controlled outlet switches to add automation to his plug-in devices. An RF remote that controls the switched outlets has been connected to an Arduino. The router communicates with the Arduino via a serial connection. And the router is controlled by a web interface which means you can use a smartphone or other web device to control the outlets.

The best thing about this system is the power that the router wields. Since it has an underlying Linux kernel you have the option of setting CRON jobs to turn lighting on and off, and group settings can be established to set up a room’s lighting level for watching movies, hosting guests, etc. Combine this with the fact that OpenWRT can use port forwarding for Internet control and the possibilities really start to open up.

With iPad, home automation would be much easier system to be installed and implemented – and the price would be more affordable.

iPort has introduced two new products in its Control Mount Series for the Apple iPad and iPod touch.  The CM2000 Control Mount for iPad and the iPort CM100 Control Mount for iPod touch both integrate the handheld Apple touchscreen products in an in-wall frame, transforming them into in-wall touchscreens for display of weather, news, stocks and many other preferred Apps.

The CM100 also transforms the iPod touch into an in-wall Internet radio source, and connects to any stereo or audio/video receiver.  Users can download their choice of any Internet radio apps available in the Apple App Store and play the audio back through any connected stereo system.
The CM2000 (US$499) and CM100 ($250) may be installed in either a vertical or horizontal orientation, depending on the functionality and design of the room.  When installed into the iPort, the iPad and iPod touch remain constantly charged.

Nine Predictions for Smart Buildings in 2009

Sunday, February 1st, 2009



1.  Manufacturers of BAS devices will convert many of the devices to DC power, allowing Power-Over-Ethernet (POE) to be used, thus spurring greater penetration of IP protocols in the BAS world. Known as the most under-valued building technology, POE will drive the convergence because of its cost advantage and management functions. Innovators in this arena will be second tier and Asian BAS companies.

2.  Just sensing whether a building space is occupied or not, will no longer suffice. Systems will need to provide real-time information on how many people occupy the space and where they are located. This will just continue the march to real-time sensing of everything that occurs in a building. Next will be the introduction of “sensor dust” which can be added and embedded in wall coatings. Buildings will have so many sensors installed, that facility management tools will become 3-dimensional.

3.  Smart commissioning will render obsolete what we now think of as commissioning, which is typically a one time or periodic event. Commissioning will no longer be something you may do once a year or every couple years, but something done in real time using sophisticated, rules-based software. Generally re-commissioning an existing commercial office building has an average financial payback of 8.5 months, which is very attractive. However, smart commissioning will have a payback period measured in minutes and will become a standard feature of high performance buildings. (more…)

Automate Your Home

Sunday, July 13th, 2008

house_sky.jpgIt’s every nerd’s fantasy — a “smart house” that knows when you left the lights on and turns them off, adjusts the heat and A/C according to the outside temperature, closes the blinds in the afternoon sun and reminds you to get milk at the store.

It may sound like something out of a 1980s sci-fi movie, but it’s not as far-fetched as you think. In fact, home automation is a burgeoning market with all sorts of toys available.

For most part, it’s a playground limited to a few lucky dot-com millionaires. If you happen to have sold YouTube for a billion dollars, just find a contractor who specializes in this stuff and pretty soon an automated voice will announce when the milk is low.

Fortunately, the rest of us aren’t completely left out of the home automation fun. But this stuff gets pretty geeky pretty fast, and it definitely helps to have some background knowledge about electronics and networking before diving in.
