Low Power Computers?
by Andy McCallum

Rate this Message:
Hi,
Is anybody running MH on a low-power consumption computer? If so, what level of computing performance is the machine? (I use MH on Linux, so the questions below assume Linux.) I am thinking of rebuilding my 200 Watt guzzling MH machine, onto a 5 Watt 500 MHz AMD Geode LX800 CPU, 256 MB RAM board (in particular this one http://www.yawarra.com.au/hw-alix2.php). The advantages are no moving parts and longer life on the UPS during power outages. The power saving alone will pay for the machine in 2 years. Before I reinvent the wheel, how has everybody got around the issues stemming from low power CPU and no local hard drive storage.
Thanks, Andy. ------------------------------------------------------------------------------ Come build with us!

What about one of those solid state drive netbooks. They use very little
power, built in UPS and monitor. They are fairly inexpensive $200 to $500. http://www.teleread.org/2009/07/30/199-acer-netbook-with-89-inch-screen-16g-solid-state-drive-and-win-xp-home-e-reading-possibility/ Just a thought.

I have a test-installation running fine on an Alix.1d with 4GB Transcend industrial CF as "HDD". powerful enough for mh in any way..
IMHO its the perfekt 5W platform for such things, I'd just take an alix.1d instead of alix.2 because the presence of a "real" BIOS and a VGA/PS2 port is very helpful sometimes ;-) At least for installing it. - The CF, if your use the right one as mentioned above ist no issue (I do stress tests for ~ 11 months with 24x7 writing now with it on a regular ext2fs, no failure on 9 boxes so far..) - rrd-generation: now, its no Xeon Quadcore ;) But its done within ~10-60 secs per graph heavily depending on the size; 200x400 ist quick, 600x1200 is dead slow.

I haven't tried it yet, but if you are interested, though it isn't X86,
the Sheeva Plug ($99.00 USD) may fit that bill.

Hi, I've just bought a Bubba2 from Excito. Currently moved all my file sharing to it, printing, mail collection and my Squeezeboxes/SliMP3s (6in total). Next thing to do is to move MH to it. I've actually been holding off moving MH because of RRD graphs for my weatherstation.

Good suggestion. Do you know which Power PC chip they are using? I couldn't find any significant detail on the website. Potentially it is a similar performance to the Alix I am looking at.

Wow. Thanks everybody for your replies and information. I am excited that Michael M. is already running an Alix, especially to hear that a CF card is handling ext2fs with regular writing. Looks like the Alix.1d is the one I will get too. The Industrial CF card is a good idea, but in Australia they are 4 times the price of standard CF cards. I wonder if the life increase is worth it? Big thanks to Raphael J. for suggesting rsyslog. I wasn't aware of it but it looks perfect for the various text log files in my automation setup. I particulary like the fact that if the rsyslog server goes down there is no impact on MH operation. Hopefully, there will be no regular writing to the local file system on the CF card. (I will have to work out a way to have MH log output picked up by rsyslog without writing it to the CF card.) Andy.

All,
Maybe a late reply but I am running MH on openwrt (OS) that runs on routers and other small devices like the NSLU2. I have written a little post about the setup on my blog. http://blog.export.be/2009/03/how-to-install-misterhouse-on-openwrt-kamikaze-809/ Also very low power consumption.

I have taken the plunge and ordered an Asus EEE PC, the 1000HG for AUD$400. It has an N270 processor which should be more than enough power and even has a 160Gig H/D which I plan to only boot off and then allow to shut down, with logging sent to the house server. Unfortunately, it doesn't quite meet my objective of zero moving parts, but the price/performance was too good to pass up. As pointed out previously on the list (by whom I can't remember) I also get a screen and keyboard located right next to my headless servers under the house. Andy.

initial MH / XP / Insteon / PLM setup.
by clabrown

Rate this Message:
Hi All:
Trying to get initial setup of MH / XP / Insteon / PLM setup running. Currently have1 RemoteLink controlling 1 LampLink manually using 2 access points. I think I have MH installed and updated using TortoiseSVN in C:\misterhouse\mh with a mh.private.ini in C:\misterhouse. I started with the mh.private.ini from the MH / Insteon starup wiki, and changed it to set the code directory to what was an empty dir c:\misterhouse\gvi_code, but it now has some 4 files that MH must have created as defaults, still using the original data directory. Also changed the location information and timezone info, and finally commented out the last line "web_refresh = 0" because that seemed to make the MH webpage on localhost show up as blank with a single "0" in the upper left hand corner. I also went to the Setup MrHouse/CommonCodeActivation and enabled the first Insteon parameter. Now under Browse Catagories an Insteon button shows up, but it does not seem to have any entries. and clicking the Scan all link tables "Run" button shows a message of "No response resulted from the last command". My PLM is connected to COM1: but I haven't found anywhere to specify that, and I suspect the "Insteon_PLM_serial_port = /dev/insteon" line from the example ini in the wiki is probably irrelevant since XP does not have a /dev directory like linux. I suspect that it's not communicating with the PLM since I don't see where the COM port or parameters may have been specified... also I'm not really sure how to tell if it's communicating. I'm hoping that I don't have to tediously type in a table of insteon addresses. I'd like to do 3 things before Monday: 1 prove it's talking to insteon ... manually toggle a light through MH? 2. same thing for some old X10 modules I've already got. 3. setup simple timer program ...(ie garage flood light on at dusk, off at 23:00) Any help would be appreciated.

Correct. I know nothing about windows but you should find the mh windows documentation portion that explains where the right ini file should be and use COM1 instead of /dev/insteon > where the COM port or parameters may have been specified... also I'm not > really sure how to tell if it's communicating.

If you can see your PLM in the list of insteon devices and sync to it, you're communicating (but you're not there yet) > 3. setup simple timer program ...(ie garage flood light on at dusk, off > at 23:00) you'll find plenty of examples that came with the code, you can copy one in the code directory, whereever that is on windows For instance: # Example use, turn the patio lamp at 10 minutes before sun set if(time_now("$Time_Sunset-0:10")) { $fmr_light->set('50%'); } Example use, turn the patio lamp off at midnight if(time_now "07:14 PM") { $fmr_light->set(ON); } if(time_now "07:16 PM") { $fmr_light->set(OFF); } Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.

That's correct, they are equivalent. Worst case you can stick your settings directly in mh.ini.

Pete,
I use a nslu2 running Debian Linux to gather data with digitemp and it works well. One big downside is that a nslu2 that has not been modified will not automatically restart after a power outage. This can be a real bummer if the power fails when you are away form home. For about the same money you can get an Asus WL-500gp router which will run mh with openwrt and may be more flexible.

Letcher,
Been there I opt for the nslu2 with some hardware hacks . Now 4 USB + hardware rs232 :) Openwrt also runs on the wrt54g series linksys wifi routers..
