Believe it or not, a magnia sg20 is almost perfect for running MisterHouse.
So what is misterhouse? Goto http://www.misterhouse.net for more info, but basically it is a home automation program utilizing x10 technology.
I already had several x10 devices in my house, but automating them was a pain. Timers have to be reprogrammed constantly due to sunset differences all year. Timers do not allow for "conditional" programming. A computer program is great, but you have to run a computer 24/7 and they are all windows based. If you have a magnia you are running a computer 24/7 anyway, so all that's needed is a x10 program that runs on linux. Enter MisterHouse, it's pearl based so it's platform independant.
Installation is fairly straightforward, although programming it takes some serious learning.
One problem though... the magnia has no serial port for the x10 interface.
I managed to overcome this problem by using a network based serial port. The Comtrol Rocketport can be utilized with a magnia, and the older version can be had on eBay for less than $50. Here is the new version: http://www.comtrol.com/products/hardware/rpsh_si.asp
More explanations when I get round to it... or when somebody asks for details.

Something I am very interested in doing. But I know almost nothing about Linux. I would be very interested if you could walk me through this. And even more if it will work with a Pocket PC.
Thanks

Yes! It can be configured to be operated from a pocketPC !
You need a "real" pc to act as the server.
It works fine in windows, you just need to install perl (free).
I wouldn't recommend windows, unless it's NT or 2000 server, for this task though.
Read a bit more at misterhouse.net
I run it on my Magnia SG20, since it's already running 24/7 anyway.

Well I also have a Magnia SG20, that runs 24/7, and one of the reasons I got it was to to do home automation. But I'm to cheap to go the Stargate route. So your setup looks like it might be something I can afford.
My biggest problem is I don't know anything about Linux. So I need a lot of hand holding when it comes to simple things in Linux. I download and installed Bastille, to harden my SG20. But I'll be darn if I can figure out how to start it.
So I would be most grateful, if when you had the time you post instructions on how to get it working. Steps that will work with/for the not to bright!
Thanks
Thanks,

Follow the steps in the articles to:
1. get full ftp access
2. install webmin
then start exploring your machine via the webmin interface.
Once you get that far, and get a serial port (I did it with a comtrol rocketport serial hub) ...
THEN you'll be ready for home automation.
I have posted instructions for making the rocketport work.
Installing misterhouse is fairly straightforward, the linux instructions are available (as well as the program itself) at http://www.misterhouse.net.
After installing misterhouse, you need to do two things:
1. Edit mh.private.ini and set your local parameters
2. Create your device and control files
I will try and make a quick start guide soon.
This is the setup I have working in my house and two other family member's houses. I have not found any commecial software for home automation that works in linux. Also, keep in mind that the stargate option has remote control only! Misterhouse allows scripted events.

Well I now have added an SG30 running Build us 3.1.0-74. Any chance you'll have time to walk me through adding MisterHouse to this unit? I've got Webmin 1.300 running on it to. This build does not seem to support the old Orinoco 802.11b cards, any thoughts on getting it to work with the old card? It seems it only supports the 802.11g card.
I'm thinking of upgrading the SG30. As I understand it the SG30 will only support a 137 GB drive, which means a 120 GB drive I believe. I am wondering if the faster drives 5400 rpm and 7200 rpm might be worth it on the SG30, any thoughts?
To me it's not clear if this means the USB drive is limited to a max of 137 GB as well?
Thanks

Goodness! I totally missed this post! Hope a very late response is still helpful. Here goes:

E-mail me that you still want to do it, and I'll write it up! Get your CM11 ready! I can't help you with X10 USB interfaces.

There are many, many posts on the SG20 Yahoo user group on how to use alternate cards. I don't use the Magnia wireless myself - I use access points, which can be had for cheap. I would welcome a step-by-step for an article here if you feel up to it.

A faster drive might speed up boot times a little, I can't see it helping with anything else - RAM is the upgrade that makes the most difference.

The capacity barrier you are encountering is due to the ATA Interface Limit (128 GiB / 137 GB) Barrier. Since USB is OS device-driver based, the next limit will be imposed not by the ATA devices but by the 32 bit operating system, this limit will be at 2.2 terabytes (2,200 gigabytes).
