This describes how to setup OLA installed on a GuruPlug. These devices make excellent low cost DMX512 nodes. For a list of compatible USB devices see the main OLA page.


  • 2 Gig Ethernet ports
  • Wifi 802.11 b/g (not recommended for lighting control)
  • 2 USB ports
  • Cheap ($99US)


This assumes you have a shell on the guru plug and that it can contact the internet to download the packages. Note that the default guru plug is insecure and comes with a lot of extras (samba, mysql, lighthttpd etc.) that aren't required. Fixing this is outside the scope of this tutorial.


Add the following line to /etc/apt/sources.list:

 deb ./

Then apt-get install ola:

 $ apt-get update
 $ apt-get install olad


Add a user ola for the daemon to run as:

 $ adduser ola 

If you intend to use USB devices, you need to add this user to the plugdev & dialout groups. Modify the lines in /etc/group:


Finally add any udev rules that you'll need. See OLA Device Specific Configuration


Change to the ola user and the start the daemon:

 $ su ola
 $ olad -l 3

Now connect the the GuruPlug on port 9090 with your browser to configure it.
