Hardware

Picking The Right Components

The Core

Most important, is the "Core". This is the main LinuxMCE server that runs all the applications. A commercial version uses a high-end server with RAID-5 storage.) You'll probably be able to get by with a good Pentium 4, at least 80 GB of storage and two network cards (Gigabit ideally).

It would be best to use a dedicated core, which means you can put this computer somewhere out of the way and not connect a monitor to it. If you are using only one computer for your system, then you've chosen the "hybrid" system, which means that your core will also be your media player. You'll definitely need a monitor or TV for this system!

Here are some possible Core server platforms.

Media Directors

Media Directors (MDs) can also be generic PCs, but are better when they have an output for a television set such as S-video or RCA jacks. Having a good sound card is also a good idea. The MDs play all your streaming music and video from the core, network attached storage (NAS), or any other MD in your home. Output to a TV and speakers for an awesome multimedia experience.

Here are some possible Media Director platforms.

Orbiters

Orbiters are high-tech remote controls. LinuxMCE provides for multiple orbiter options such as a generic PC, wireless tablet PC, PDAs, mobile phones running Symbian or Microsoft Mobile, or through a web interface that can be accessed by any computer inside your network or through the Internet. (The web interface requires user authentication, but currently not with SSL.)

Here are some possible Orbiter platforms.

Network Attached Storage

An alternative to having a lot of storage space in the core is to have a small hard drive for the core and store all your files on a network attached storage (or NAS) server. The Buffalo Terastation is 1.0 TeraByte RAID-5 and under $1K(US). Having a NAS will allow you to not lose your precious media files. You'll likely want the larger storage for your collection of music and videos. Keep in mind that your LinuxMCE system can also record TV shows (using MythTV) and video from your security cameras (using Motion).

Here are some possible NAS solutions.

Additional Devices

Home automation devices for controlling your lights, security cameras, a plasma screen TV, a streaming media music player such as the SlimDevices Squeezebox, an alarm system with a serial interface, etc. These are examples of devices that require another controller device called a gc100. This allows these and other devices that communicate using a serial port (e.g. alarm panels) or an infrared port (e.g. a TV) to connect to the network and talk with your LinuxMCE core.

Plug 'n' Play Capabilities

Once LinuxMCE is installed, you can treat it like an appliance -- plug it in, turn it on, and leave it alone. You don't even need to install any software on the media PCs that will be used as Media Directors. If these PCs are connected to the Core by wired Ethernet, they can usually be set to boot LinuxMCE from the Core server over the network whenever you want to use them as a Media Director. The rest of the time they can be used as a regular PC, using whatever operating system is on their hard drives.

The LinuxMCE Core must be your LinuxMCE network's DHCP server so that it can offer the plug-and-play and network boot services. You cannot have 2 DHCP servers on the LinuxMCE network. In our Core, it is recommended to have dual network cards -- one for the "external" network, (your home LAN to which your Internet is connected), and one for the "internal" LinuxMCE network (to which all your LinuxMCE devices are connected). For the LinuxMCE "internal" network, the LinuxMCE Core server also effectively acts as a firewall.

Note that you can easily have PCs outside of the LinuxMCE internal network, if you choose. Simply do not connect them to the switch/router which is connected to the LinuxMCE Core.

Wiring Considerations

Additional Hardware Resources

Choosing hardware components can be difficult. There are multiple articles regarding hardware selection in the Hardware Category.

Also see:

Setting Up The Hardware

There are many ways to install LinuxMCE, and lots of options for equipment. However, the key components in a LinuxMCE system are the Core (the PC acting as the master server), Media Directors (media PC's connected to your TV's), and Orbiters (remote controls-web pads, pda's, mobile phones, etc.).

I will use my own PC's

First a warning LinuxMCE is Linux-based, but don't worry. Sometimes drivers are not available for Linux as soon as they are for Windows. Particularly, if you bought some new, exotic hardware there may not be drivers. If you're looking to get some new hardware to run LinuxMCE you may want to check sites the following Locations:

If you already have the hardware it can't hurt to try.

You will need one PC to run the Core software. Although you could install the Core on top of your existing operating system, or build from source, it will be tricky and you will miss out on a lot of features. You really need to use our own distribution because, in addition to our own software, LinuxMCE also includes lots of other open source projects, like Asterisk, Firefox, Xine, VideoLan, MythTV, etc. We built "wrappers" for all of them which is how we get them all to work together seamlessly. For example, if you start watching a movie in 1 room, LinuxMCE will use Xine on that local media director. Use the orbiter to move that movie to 2 rooms, and LinuxMCE seamlessly detects the network capabilities (multi-cast switch, etc.), moves the video source to the Core using VideoLan, broadcasts to both rooms, uses VLC to do the rendering and changes the UI on the remote controls. If you use the vanilla packages from, say Fedora, none of that will work. Plus, a lot of LinuxMCE's more advanced, kernel-level modules, like plug-and-play, bandwidth shaping to ensure your phone calls are clear, network boot, and so on may not work on other Linux distributions and definitely cannot be done under Windows.

Note this PC should always be left on since it becomes the 'brains' for the whole house and all the other pieces won't function unless they can find the Core.

Special Requirement

There is only one special requirement. The Core needs to be your DHCP server so that it can offer the plug-and-play and network boot services. You cannot have 2 DHCP servers on the same network (not easily at least). If you have another DHCP server (like a cable/dsl modem), we recommend your Core have dual network cards: one for the "external" network, where your internet is connected, and one for the "internal" network within the house, and into which all your devices are connected. This makes LinuxMCE act as a firewall, and allows it to co-exist with another DHCP server. If you have a DSL or cable modem that needs to be the DHCP server it won't be a problem--just plug it into the "external" port. LinuxMCE's DHCP server only operates on the "internal" one. However, if you have only 1 network card in the Core, you will need to be able to give it a static IP and disable the DHCP server in your DSL/Cable modem. Otherwise you will have to disable LinuxMCE's DHCP server and lose a lot of functionality.

Adding Additional Hardware

You can also put other cards in the Core, such as analog phone line interfaces from www.digium.com for the phone system or analog video capture cards for surveillance cameras. You can put the PVR/satellite capture cards in the individual media PC's, or you can put several in the Core, which will share the video throughout the house.

Wherever you have a TV/Stereo you can use a PC or thin-client as the Media Director--it doesn't need to be on all the time and there's no software to install since they will network boot off the Core. Just be sure it has a good Linux-compatible sound card, a Linux-compatible video card, supports PXE network boot (nearly all recent motherboards do), and--optionally--a PVR card. To use the Bluetooth mobile phones as remote controls, add a USB Bluetooth Dongle for each media director (around $25). All the media directors will report the signal strengths of all the mobile phones--this is how the Core figures out what room you're in. Since all resources in the whole house are shared, you will be able to control any device in any room from anywhere--as long as you're within Bluetooth range of any media director (about 10m or 30feet), you will have control over everything in the house. You can also use low-cost network audio players, like the Squeeze Box, wherever you want to add music.

To control the system, you can use the PC's mouse and keyboard, or an infrared remote, or run the Orbiter software on your mobile phones, webpads and PDA's.

Also view our Hardware Category to see what 3rd party devices will work with LinuxMCE, like lighting control systems, cameras, alarm panels, etc.

A Dedicated Core

Connects to a Dedicated Core

The Core is the central point of the LinuxMCE system and runs applications and daemons needed for the other devices to exchange messages. A dedicated core will run all of the LinuxMCE components, it really means that the user will not be using the Core as a Media Director as well.. You'll need to use additional Media Directors to be able to play movies, listen to music and watch TV. This kind of setup is recommended when you have lot of extra devices, this way the back end applications will have full access to Core's resources. This method basically means your main server will be tucked away in storage closest and will not be used as a Media Director.

There is work currently on getting a Clean Core working, to further reduce the resource consumption of the Core.


A Dedicated Hybrid

Connections to a Hybrid Core

A "hybrid" just means the computer that is running is the "Core" software is also running the "Media Director" software-you use the Core as a Media Director. The only reason we don't recommend this in our high-end installations is because a computer suitable for a Core is usually a pretty massive box with major hard drive capacity and rather noisy, so it's shoved away in the wiring closet, rather than sitting next to a TV like a Media Director would. However, you can use a regular PC as the Core + Media Director (Hybrid) also. Just remember that it will need to always be on since the Core software is what controls everything in the house.


Be sure you complete the installation of your Core/Hybrid before trying to boot the media directors.

Installation of Software Components

There are currently two methods of installation. The DVD installation which only requires the downloading and creation of a single installation disk, and the 3 CD method which requires 3 disks, but offers more flexibility in installation.

Setting Up LinuxMCE

Tell LinuxMCE About Your Home

Tell LinuxMCE about your home shows you how to use LinuxMCE to get all of the information about the current installaion. In about 2 hours you can have everything setup--the whole-house media server, full control all your lights, climate, and tv/hi-fi gear, the phone system, follow-me, everything. It's quick, painless, and non-technical.

Setting up your LinuxMCE system consists of 4 things:

  1. Providing some general information, such as what kind of network you have.
  2. Creating the devices (lights, tv's, cameras, etc.).
  3. Creating your scenarios. A "scenario" is a group of commands, or tasks, you want executed when you touch a button. Each scenario you create will appear on the Orbiters as a button. Scenarios are generally organized into 5 categories: lighting, media, climate, security and telephone. You can create, for example, a lighting scenario called "Entertaining" which turns on all the lights in the house and in the front yard. A button labeled "Entertaining" will then appear on the Orbiters in the lighting section--touch it to activate the scenario. Any scenario can do anything. For example, just because the "Entertaining" scenario is a lighting scenario doesn't mean the scenario only affects lights. You can make the scenario also play some music, and maybe open the front gate. You can use the "Advanced, My Scenarios" menu option for low-level control over a scenario, to make it do whatever you want. However the Wizard includes pages that make it very easy to create scenarios. For example, when you add a lighting scenario with the Wizard, it lists all the lights in the house and lets you pick the ones you want to change with the scenario.
  4. Creating event handlers. This is how you tell LinuxMCE you want it to do something in response to some event. For example, you want LinuxMCE to turn on the Front Porch light when a motion detector is tripped. Or you want it to play a loud message on the TV's when there is a security breach. Or stop watering the lawn after it rains.

The developers have tried to automate has much of the set up as possible with several scripts and wizards. See the different wizards below, and if the wizards are unable to set up the system properly then visit the admin website for many more options

  • To get started you will want to read the documentation on Quick Start Guide
  • You will need to know if your graphics card is capable of running the UI2 with masking or the UI2 with alpha blending prior to running the wizard. Please read Graphics Test for information on how to determine the capabilities of your current video card.
  • If you are in doubt or if you want to get a working setup quickly please select UI1 which will work on any video card supported by Kubuntu.

AVWizard

The Audio/Video Wizard is designed to allow for easy setup of components which allow the Core or a Media Director to output content to the connected display, which can range from a simple CRT, to HCTV with component and/or composite inputs.

Setup Wizard

The setup wizard is an automated series of screen which allows the user to enter information and devices that LinuxMCE will control. The Setup Wizard is broken down in to two modes: Media Player Wizard and House Setup Wizard. After selection of the Setup Wizard you will see an additional screen. If the audio and video are properly setup you should see and hear a video. If this is correct please select Next.

The next screen you will encounter asks which wizard would you like to start: House Setup Wizard or the Media Player Wizard. Please select the wizard you want to begin.

House Setup Wizard

Media Player Wizard

Using LinuxMCE Admin Website

Although there are automated wizards to assist in setup, the most robust system for setup is the LinuxMCE Admin Website. The user can create and modify any and all devices that LinuxMCE can control.

You need a web browser to configure your LinuxMCE system using the built-in LinuxMCE Admin Website Since the Hybrid + Media Directors have one built in, you can just click the "LinuxMCE Admin" website to bring it up directly on the Hybrid. Or, from any web browser in your home, go to the URL: http://myip/pluto_admin where myip is the IP address of the Core/Hybrid. Login then click Wizard.

Scenarios, Events & Security

In the Scenarios page, add the scenarios, or buttons, you want for each room. Like a Lighting scenario in the Bedroom called 'Go to sleep' which dims the lights, or a security scenario in the living to view a camera. When you do a 'quick reload router', DCERouter will automatically add Media Scenarios for each room for whatever media devices are in there. But your new scenarios are not visible on the Orbiter until you regenerate--see the note below in 'Using LinuxMCE with an Orbiter'. Next add Events, in other words, when something happens (a motion detector is tripped, the sun sets, etc.) you want LinuxMCE to do this (turn on a light). Also set security options, like how you want to be notified when something happens in the house. Each page has context sensitive help to explain everything. They will take effect next time you reboot or 'quick reload router'.

Configuring Myth TV

Most of the setup for MythTV is done automatically, but for more information take a look at the following links

Upload Your Media

There will also be Microsoft Windows compatible network shares on the Core or Hybrid (uses Samba) . There is a "public" share for putting all files that the whole family can share--movies, music, etc. And there is a private share for each family member. To access these network shares in Windows, choose Start, Run, and type \\ plus the IP address of the Core or hybrid.

For example: \\192.168.80.1 Note that if you add new family members, their network share will not be available until after you reboot the Core/Hybrid. Once you copy your media into the appropriate folder, you can go into the LinuxMCE Admin Website, choose "Files & Media" and "Media Files Sync" to be sure your media is in the database, add attributes (artist, actor, etc.), and choose cover art.

Using LinuxMCE

LinuxMCE is a complicated piece of software, so proper understanding of each of the components makes for a better experience. CLICK HERE for a quick introduction and description of the terms needed to understand most to best use LinuxMCE.

Orbiter Interface

The Orbiter is quite simple to use, and all the screens are quite straightforward. Use the LinuxMCE Admin Website to configure your LinuxMCE system, including choosing the options on your Orbiter, such as lighting scenes, climate scenarios, and define what a/v equipment you want it to control.

Media Director Orbiter

Main Orbiter Screen

Orbiter is just our way of saying remote control. All the Media Directors run an on-screen Orbiter, like the one below. Choose options on the on-screen orbiter with a keyboard/mouse attached to the media director, or with an infrared remote control. The Orbiter software runs on Linux, Windows and Windows CE, and can also be run on webpads and PDA's. Either way, it works exactly the same.

In the lower right on the main obiter screen are the 'who' and 'where' buttons. This indicates what room you are in, or want to control, and which family member is using the Orbiter.

Touch either button if this isn't correct. Even if you are using an on-screen orbiter on the media director in the Living Room, for example, you can still change the location to the Bedroom. That means you would be using the Media Director in the Living Room as a remote control for the devices in the bedroom. Normally you don't change the location for an on-screen orbiter, since that device stays in a fixed place, but you do when you have a wireless web pad or pda you carry around.

Lighting Scenario Page LinuxMCE Admin Website

The icons on the left all lead to a maps, or floorplan, of your house showing your lighting, media, climate, telecom and security devices. Next to each of the floorplan icons are the scenarios for that category and the given room. In the scenarios section of the LinuxMCE Admin web site you create the scenarios for each room. You can have a lighting scenario called 'entertaining guests' that sets some lights, plays some background music, unlocks the door, and so on.

NOTE: Many orbiters have relatively slow processors (like PDA's and phones) and may be running on slow wi-fi connections. So, the orbiters do not retrieve the large, full-size graphics, scaling them, drawing the text, and rendering everything on the fly.

Rather all the graphics on your Orbiter are pre-scaled and pre-rendered by OrbiterGen. This means that if you add new scenarios or devices, or change floorplans or skins, you won't see them immediately on the Orbiter. You must go to the 'Advanced Options' page by clicking the LinuxMCE logo on the main menu, and choose 'Regenerate this Orbiter'. You'll be asked to wait about 60 seconds or so while the renderer creates new graphics, and then the Orbiter will reload.

Mobile Orbiter

Unless you turned off the "Auto Detect new Bluetooth Phones" option for the Media Director, compatible Bluetooth Mobile phones will automatically be detected when they are within range of any Media Director if they have Bluetooth turned on. A message will appear on all the Orbiters asking if it's a phone, and if so, to whom it belongs. Be sure you add your family members to the LinuxMCE Admin web site before doing this. Also, you may need to turn on the TV to see the message on the on-screen orbiter.

If you choose to install the software, the phone will beep. Just hit 'yes' to accept the software, and accept the default prompts.

The mobile orbiter works pretty much like a regular orbiter. The difference is that you don't usually need to worry about the "who" and "where" button. The "who" is determined when you chose to install the software. That family member is assumed to always be the user. And the "where" is automatic-whenever you come within range of a media director it will automatically switch to the correct location. You can press the button under the location if you want to control a location other than the one you are in.

Since the display is smaller, rather than showing all the scenarios on the main menu, you must first choose the category, like lighting, and then choose the scenario from the sub menu that appears. You can also hold the category to toggle 'follow-me' mode, indicated with a red F. So, if you hold down the 2 button, a red F appears for media. Now as you move around the house your media will follow you. All 5 categories have follow-me.

Troubleshooting

This troubleshooting guide assumes some basic knowledge of Linux. In LinuxMCE, everything is a device. In the LinuxMCE Admin Website, you can choose Devices, to see a list of all the devices in your installation. We recommend you don't make changes here - you can break things! The top level device is usually a computer, either the core or a hybrid or an orbiter. All the logs for the devices on that computer are stored in /var/log/pluto. You can ssh in to the core using the root password you chose, and from there, you can ssh to all the media directors-shared keys were automatically setup.

All current activity is logged in the file that ends in ".log". At bootup, certain device logs are archived into /var/log/pluto/*.log.*.gz files

All DCE devices are running in separate screen sessions. Type "screen -ls" to see all active screen sessions, and "screen -r PID" where PID is the id you saw in the -ls list to attach to the screen session. There is not much for you to do or see though since all the output on stderr and stdout is going into the logs. DCERouter is running the same way on your core or hybrid.

At bootup, all the scripts listed in the LinuxMCE Admin Website under Boot Sequence are run. If any programs crash, a core dump file is put in /usr/pluto/coredump.

If you're a programmer, you can also check out our Programmer's Guide. If you want to learn about writing DCE Devices, see the DCE.
