Smartlinc Android App

Saturday, February 19th, 2011

Here are the beginnings of an Android app that I've built for Insteon's Smartlinc:

Smartlincr Smartlincr

Upcoming features:

  • - device status
  • - dimming capability (code is already there, just need the UI)

There's one sentence on Smarthome's product page for this controller that reads: *Browsers running on Linux are not currently supported From what I've read on various blogs and forums, there's a bug that causes a 4 second delay for HTTP requests and it has more to do with Linux than which browser you use. So, because Android is Linux based, the bug is apparent in this app. Fortunately, it is an asynchronous 4 second delay. For example, you can tell a light to quickly turn on and off 5 times in a row and in 4 seconds the light will turn on and off 5 times as you commanded; it won't take 4 seconds for each command.

Feel free to leave a comment below if you have a question or feature request!

Slicehost – Ubuntu Quick Setup

Tuesday, April 21st, 2009

I've been looking at different hosting options for the past few weeks (mainly dedicated and virtual private / virtual dedicated). It seems as if they're all out to nickle and dime you to death. "Oh, you want your server to be connected to the internet?... that'll be an extra $20/mo please". They don't even really say "please" (I threw that in myself). Through some forums, I discovered a company called slicehost. They only sell VPS plans, but it seems as if they know what we (the developer) want. It says so right on their website. They offer multiple flavors of Linux installs and you have full root access to them along with a bunch of other features. Last year Slicehost was aquired by the mighty RackSpace, one of the top hosting companies in the world.

Everything sounded interesting, so I decided to try my first "slice". I went with the 256, knowing that I can upgrade at any time. After you pay, your slice is ready within minutes and your ip address and root password are emailed to you. I chose to go with an Ubuntu image (8.04 LTS) and I'll show you how to get it up and running ASAP!

If you like this tutorial and think would like to try out a slice for yourself (currently starting at only $20/mo.), please don't be affraid to use my refferal link:

Go ahead and login to your server (I use PuTTY for Windows for my SSH needs). The first thing that you'll probably want to do is change your root password and then setup a user for yourself, so that you won't be working as root all of the time.

Next we'll install Apache 2:

sudo apt-get install apache2

... and then MySQL. Be sure to set your root password:

sudo apt-get install mysql-server

For MySQL management I installed phpMyAdmin (this will also install PHP as a dependency):

sudo apt-get install phpMyAdmin

As an extra admin tool, you can install Webmin. I just downloaded this into my home directory with wget:

wget http://link_to_current_webmin.deb

To install Webmin you can use (replace current_webmin.deb with the name of the deb file that you downloaded with wget):

dpkg -i current_webmin.deb

It will probably fail due to a lack of dependencies, so you can run apt to fix it. This should also continue the Webmin installation:

sudo apt-get --fix-broken

You should now be able to access your server at: https://your-ip-address:10000
You'll have to add an exception to your browser for the invalid SSL cert. It's ok to do so.

Lastly I just installed ProFTPD, for my FTP server, through Webmin. There's a one click install under unused modules or you can use:

sudo apt-get install proftpd

Once this was installed, I used Edit Config Files to uncomment (remove the '#') "DefaultRoot ~" (this allows users access to only their home directories) and add the line: "IdentLookups Off" (this speeds up the login process).

At this point, Webmin showed my memory usage at less than half (102MB) of the 256MB allotted and my disk usage at around 1.2GB of the 10GB for this plan! I just set my slice up, so I can't comment on it's performance as of yet.

I hope this is a good start to get you up and running. I can't guarantee that this is the most secure setup, but it's a start...

LinuxMCE Includes Insteon Support (Beta)

Saturday, January 12th, 2008

Insteon support from the Linux MCE project has finally arrived. Linux MCE is open source -

"whole-house media solution with pvr + distributed media, and the most advanced smarthome solution available"

- software for linux. LinuxMCE has recently announced beta support for the PLM 2412s module. This Power Linc Modem (PLM) is a simpler version of the, more common, Power Linc Controller (PLC). It has the ability to send both Insteon and X-10 commands, but not as a stand alone unit.

LinuxMCE provides drivers, written in Ruby, for both the PLM and the EZBridge. The EZBridge "bridges" your Insteon controller to your ethernet network. The EZBridge isn't cheap though ($154.99 at the time of this writing). Being that it's an ethernet device, it could potentially allow you to control your devices while you're away from home.

While this doesn't seem like a huge leap for LinuxMCE, it definitely shows that Insteon won't get left in the dark.
