How to Make an Alexa Smart Screen with Raspberry Pi

In this guide, we'll install the Alexa Smart Screen SDK on a Raspberry Pi 4 to “create” our version of the Echo Show. This project will be known as “PiShow.” This project is made feasible by the Amazon Alexa Smart Screen SDK as well as the Alexa Voice Service (AVS) SDK, which we detailed in our previous post, How to Build an Alexa Speaker with Raspberry Pi.

PiShow Warnings

  • PiShow is not meant to be a replacement for the Echo Show. Although many of the Echo Show's capabilities are present in this version, significant capabilities, like the ability to play videos natively, were purposefully left out.
  • The vocal wake word trigger “Alexa” is not included in this smart screen version of AlexaPi. While speaking to Alexa, the user will hit the ‘A' key.
  • PiShow cannot launch when VNC is running. On the Raspberry Pi, VNC must be disabled.
  • Music: Using a Pi touch screen, the user may pause music. The music capabilities are identical to those stated on the AlexaPi page.
  • Alexa Skills are accessible on PiShow, and any visual screens inside an Alexa Skill are also visible on PiShow. Moreover, Alexa's skills have touchscreen functionality enabled.
  • If you use a touch screen and tap the screen while Alexa is speaking, she will stop speaking. This is the same behavior as with the Echo Show.

Why Build a PiShow?

In our previous post, we discussed the cost difference between purchasing AlexaPi project components and an Echo Dot. In this article, we fully reveal that it is less costly to purchase an Echo Show than the components for a PiShow.

This can be a fun weekend STEM project if you already have a Raspberry Pi and a touchscreen. The fun is in creating and discovering how voice technology works behind the scenes.

What You Need to Make an Alexa Smart Screen with Raspberry Pi

Timing: Prepare for a minimum of 3 hours to accomplish this project. Depending on your Pi model and internet bandwidth, the AVS Device SDK installation step takes around 2 hours.


Complete the entire project, as detailed in our previous article, “How to Build an Alexa Speaker with Raspberry Pi,” before starting this tutorial.

The majority of this tutorial is focused on terminal commands. We strongly recommend reviewing 25+ Linux Commands Raspberry Pi Users Need to Know first if they are unfamiliar with terminal commands on your Raspberry Pi.

PiShow Setup and Install

  1. As detailed in our previous article, “How to Build an Alexa Speaker with Raspberry Pi,” complete the AVS installation.
  2. Press Ctrl-C to halt the script if your AlexaPi is currently running. The speaker, microphone, and power should all still be connected.
  3. Attach your screen. The PiShow version now includes a 7″ Raspberry Pi Touchscreen. But, you could use a touch screen from a third party that connects via HDMI or the GPIO ports. You can purchase similar screens on Amazon for as little as $25. You cannot use those functionalities if your screen is not touch-sensitive.

Can Raspberry Pi work with Alexa?
  1. Open a Terminal.
  2. We'll start by creating the folders and installing the libraries and applications we'll require for PiShow. Type the following commands:
cd /home/pi

mkdir sdk_folder

cd sdk_folder

mkdir sdk-build sdk-source third-party sdk-install db

sudo apt-get -y install \
git gcc cmake build-essential libsqlite3-dev libcurl4-openssl-dev libfaad-dev \
libssl-dev libsoup2.4-dev libgcrypt20-dev libgstreamer-plugins-bad1.0-dev \
   gstreamer1.0-plugins-good libasound2-dev doxygen

pip install commentjson

Your Pi may already have commentjson installed.

  1. Next, we will install PortAudio to record microphone data.
cd third-party

wget -c

tar zxf pa_stable_v190600_20161030.tgz

cd portaudio

./configure --without-jack
Can you get Alexa with a screen?
  1. Run ‘make’ in the PortAudio folder. This command took around 1.5 minutes on a Raspberry Pi 4.

  1. Go back to your Terminal and enter the following commands to start your PiShow.
cd $HOME/sdk_folder/ss-build
 PA_ALSA_PLUGHW=1 ./modules/Alexa/SampleApp/src/SampleApp -C \
 $HOME/sdk_folder/sdk-build/Integration/AlexaClientSDKConfig.json -C \
 $HOME/sdk_folder/alexa-smart-screen-sdk/modules/GUI/config/SmartScreenSDKConfig.json -L INFO
  1. As in step 21, you may need to authenticate the PiShow sample app. If so, scroll up to find your code in the Terminal, then navigate to and enter it.
  2. Go back to your Chromium browser, and you should see the message “Press and Hold “A” then speak”.

  1. Give it a try! Quick note: index.html in Chromium must be the active window for PiShow to work. Hold down the ‘A’ key while you say, “Tell me the weather.”

Congratulations! You have made your PiShow!

Controlling Raspberry Pi Using Alexa

Always use the same process: With /home/pi/sdk_folder/ss-build/modules/GUI/index.html as the active window, hold down the ‘A’ key while speaking to Alexa. You do not need to say the wake word, “Alexa”.

Things to Try on Your New PiShow

  • “Play Music”: If using the touchscreen, you can pause the music by tapping the pause button on the screen.
  • “Tell me a joke.”
  • “Open Big Sky” is a weather app with great graphics.
  • “What does planet Earth look like?”
  • “Enable Space Station”

Go back to your terminal and press Ctrl-C to end PiShow.
