Hardware devices



  • currently only the colored lights works with link project
  • A19 has 2 different bulb types, Lux and one that states white & colored. Lux is white and dimmable only.

  • be sure to get the 2nd generation (should be 1st generation compatible) ie. Philips 456194 Hue White and Color Ambiance Starter Kit, A19 Starter, Standard Packaging
  • There's another white only kit, don't get that one yet. ($75 w/ 2 bulbs)
  • The hubs from both the Color kit and the white only are the same hub models. You can get a colored light to work on the white starter package. If you get the wrong kit, you just need to get the right bulb.


  • be sure to download the app on your iphone or android device and setup the hub.

adding a new light

  • on the iphone : -> go to settings -> my lights -> +connect new lights.
  • Make sure the light is near the Hue Hub; ZigBee spec for linking is that the devices need to be within 30 centimeters of the hub.

Raspberry Pi 2

  • Highly recommended to have a heatsink for your raspberry pi. Certain Raspberry Pi sets such as complete kits from Vilros will include heat sinks.

Version Check

Make sure you are on jessie and not wheezy; you can do this by :

more /etc/apt/sources.list
  • If you see wheezy, then it's wheezy. If it says jessie somewhere, then it's jessie.

Upgrading from Wheezy

There's 2 ways :
1. let the system upgrade:

sudo nano /etc/apt/sources.list
change wheezy with jessie 
sudo apt-get update && sudo apt-get dist-upgrade

2. reinstall the OS. There's 2 ways to do this. NOOBs or using an image; NOOBs is probably easier for most people.

  • If you're going to do this on a mac, I suggest using Apple-Pi Baker:
  • if you reformat the card, make sure you use FAT16, or FAT32; 64 MB or higher might end up formatting in exFAT which won't work; it also has to be formatted to have a bootable MBR (Master boot record)
    • Note : Apple-Pi Baker will format like this with the format button so you don't have to worry about making these settings; SDFormatter won't by default

Steps for install

One and Done task :

post install

Make sure your libs are up to date

sudo apt-get update && sudo apt-get dist-upgrade

setting a password

You may also want to set a password on the device, if the noobs didn't ask for you to set one up: Menu -> preferences -> Raspberry Pi Configuration -> Password The user would be Pi

Reseting the Device

One and Done task :

  • tip: if you have a Mac and Apple-Pi-Baker, you can backup your image from the SDcard, and then restore from a frozen build which might be better than having to setup from scratch.

Raspberry Pi 3

See Raspberry Pi 2 section.

Programming language


uninstall any previous instances of rust

  • sudo /usr/local/lib/rustlib/

installing multirust

git clone
sudo ./
multirust default stable
multirust update 
multirust override nightly-2016-03-07
multirust default nightly-2016-03-07  
  • First time use doesn't work without setting a default
  • foxbox won't compile using stable.
  • override will over ride to a build
  • default will make it the default build

creating rust so that it cross compiles on pi:

choice 1

  • you most likely don't have to do this, using fabrice's tool is probably better
git clone ~/Projects/pi-tools
export PATH=~/Projects/pi-tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin:$PATH

git clone
cd rust
rustc -V
git reset --hard 998a6720b 
sudo ./configure --target=armv7-unknown-linux-gnueabihf  --prefix=$HOME/Projects/pi-rust && make && make install

Choice 2: the better choice

  1. Use ubuntu 15.10 ; doesn't seem to work on 14.10?
  2. git clone
  3. read and follow :


Project Link

Using a Fabrice Build

  1. Raspberry pi needs a lib updated : sudo apt-get install libupnp-dev
  2. use a browser and download a build : builds can be downloaded from here :
  3. after downloading the build, extract it and run ./foxbox


  • Compiling for the Raspberry pi requires cross compilation to the raspberry pi.
  • it's recommended to use a Ubuntu 15.10 for now if you're going to compile for yourself


Https is turned on now, the following will only work for regular http. To turn https off, make sure you supply with --disable-tls parameter when running foxbox.

check to see if it's up :

curl -X GET --url http://<ipaddress of machine with foxbox>:3000 --head

create an account:

curl -X POST -d @credentials.txt http://localhost:3000/users/setup

The credentials.txt should be a text file that contains the following format:

    "email":"<email address>"

Note: Make sure to use double quotes and not single quotes.

logging in:

curl -X POST -H "Authorization: Basic <<64bit encoding of <user>:<password>>"

Listing Device services available :

curl -X GET -H "Authorization: Bearer <token result from logging in>"

This would also give you a list of devices and the device id.

Device State

Get the state of a Hue bulb : curl -X GET -H "Authorization: Bearer <token>"<device id>/state

Change State of the Device

curl -X PUT -H "Authorization: Bearer <token>"<device id>/state -d <json of change of state> ex. for Hue: curl -X PUT -H "Authorization: Bearer <token>"<device id>/state -d '{"on":"false"}'

For Hue:
  • red : '{"on":true, "hue":0, "sat":1, "val":0.5}'
  • greenish (not very green) : '{"on":true, "hue":120, "sat":1, "val":0.5}'
  • blue : '{"on":true, "hue":240, "sat":1, "val":0.5}'
  • off : '{"on":false}'


Project Vaani

Dev environment on mac


installing homebrew on mac
Installing Maven on Mac
brew install maven
Installing Gradle on Mac
brew install gradle
installing bison on mac
brew install bison
installing swig on mac

Note: you can probably skip this step as it's done in the pocketsphinx script :

brew install swig

Vaani version OpenHAB

OpenHAB background info
  • It may help to understand the openhab architecture :
  • mary-tts and net-speech-api are in the installations for the orchestrator
  • You can pull and compile all of them by compiling in this order "smarthome", "openhab-core", "openhab2-addons", "openhab", "openhab-distro", and running: mvn install in each directory; it's better to setup the IDE. The openhab-distro is where the distributions will compile; you can run mvn install clean to clean and install and with the -DskipTests=true to skip tests.
  • NOTE: OpenHAB 1.4 packaged everything together with a Designer and Runtime; for 2.0, Designer and Runtime are a package part of Eclipse

Troubleshooting Errors
Issues with CodeHaus downloads

From Codehuas:

Now that Codehaus no longer serves up Maven repositories, you will need to change your configuration.

If your configuration is not updated and you slam our redirector, then you may be served invalid JAR files with status 200 to encourage you to update your configuration.

Making Maven Work

In ~/.m2/settings.xml you can update the URL to be used for specific repositories.

For example:


I believe the repo we want is :

Plugin execution not covered by lifecycle configuration: org.eclipse.tycho
  • select the error and hit command 1. This should bring up the "Discover new m2e connectors"
  • select finish
  • Make sure Tycho Configurator is selected. ( uncheck Groovy-Eclipse if it's listed )
    1. ) Install Tycho m2e connector manually using Help -> Install New Software. You can use the following update site: ""; Do not forget to update your project: Select the package "org.eclipse.om2m" -> right click -> maven -> update Project.
    2. ) Make a test with Eclipse Luna RCP and Rap developers using Window -> Preferences -> maven -> discovery -> open catalog. Then find and install tycho.
Project 'org.openhab.binding.smarthomatic' is missing required source folder: 'src-gen/main/java'
  • the reason is because we're missing a PR :
  • fetch and cherry pick the PR listed in the issue.
  • turn off all building automatically settings ( ie make sure that you uncheck build automatically after cleaning and in the menu setting)
  • refresh the whole project ( select all the files and hit F5 )
  • clean the whole project
  • run the setup steps again
  • then build the whole project again
The import with org.openhab.binding.smarthomatic.internal.packetData cannot be resolved
  • verify that you have the openhab2-addons repo
  • if refreshing, cleaning, and rebuilding doesn't do the trick, you can try quitting out of the Eclipse, and rm ~/.m2 and then try rebuilding again.
  • if that doesn't work try mvn install method and then go back to eclipse once everything is compiled.
Missing Constraint: Import-Package:; version="0.0.0"
  • right click ( or control click) on the -> select Build Path -> and select "Use as Source Folder"

Source selection.png

  • Within the "run configurations..." dialog, select plugins and with default start-level and default auto-start; do the same for any other packages it's complaining about.
setting up pocketsphinx with OpenHAB
  • pocketsphinx should install now with the Mozilla Vaani version. See IDE setup.
Building smarthome
  • see for build and distribution location.
  • if you're showing errors:
    • do a clean without rebuilding
    • run the setup
    • close out of the application
    • do mvn install in the following git hub repos in the following order : smarthome, OpenHAB-addons, OpenHAB-core, OpenHAB, OpenHAB-distro.
    • reopen the Eclipse app and then retry building.
Troubleshooting issues with the Designer
= "executable launcher was unable to locate its companion shared library" for MacOS =
  1. control-click on the app
  2. from the context menu select "Show Package Contents"
  3. go into the Contents folder
  4. open the Info.plist file in a text editor
  5. search for <key>Eclipse</key>
  6. add and save the file:
  7. close out of the plist and the open folders and launch the application.

Building OpenHAB distributions
  • You can pull and compile all of them by compiling in this order "smarthome", "openhab-core", "openhab2-addons", "openhab", "openhab-distro", and running: mvn install in each directory. The openhab-distro is where the distributions will compile; you can run mvn install clean to clean and install and with the -DskipTests=true to skip tests.
  • The distributions will be moved to ~/.m2/repository/org/openhab/distro/ by default.

NOTE: sometimes running mvn clean install -U may help; -U forces an update on all cached files. If it still has issues, sometime deleting the .m2 cache may help ( ).

python scripts for Raspberry Pi

  • hue scripts :
    • note: python isn't my language, and I need to revisit cleaning the scripts. They were suppose to be a part of a cron job script that would react to data from fitbit; I stopped working on that exercise.

fitbit API

    • a fork from orcasgit/python-fitbit ; I modified it so it's easier to get the authentication going and made a small script to pull the data. Need to go back and clean up the scripts at some point; stopping the exercise for some other items.


  • error when trying to save preferences on Mac:
    • create the directory and make sure you can access it :
      • sudo mkdir /Applications/
      • sudo chown <user> /Applications/
