Using 102shows


102shows consists of two parts:

  • the lightshow server, which should run on a Raspberry Pi - it controls the LED strip via SPI - it listens for MQTT messages that tell it which show to start (and what the paramters for the show are)
  • the UI - it delivers a nice web interface - it sends the MQTT messages to the server

For the two elements to be able to communicate (via MQTT) you need an MQTT broker, for example mosquitto

All of these can run on the same Raspberry Pi but only the server has to.

MQTT broker

If you already have an MQTT broker in your network, you can use it. Else, install mosquitto via sudo apt-get install mosquitto. In any case, you will need the host, port (and maybe access credentials) of your MQTT broker for later.


For the latest stable release: In the folder you want to install 102shows in, run:

wget -q -O; chmod u+x; ./ stable; rm

This will launch an assistant that will lead you through the installation process.

Installing a development version

The setup script takes the GitHub branch to clone as an argument. So, if you want to install the latest development version (which resides on the master branch), you should run:

wget -q -O; chmod u+x; ./ master; rm

Web UI

1. Prerequisites

The web UI depends on Node-RED with the dashboard add-on.

Raspbian Tip

There is a special simple installation way for the Raspberry Pi:

bash <(curl -sL


If you have installed any version of node-red-contrib-ui, you have to uninstall it before installing node-red-dashboard.

  • Install the Node-RED dashboard add-on:
cd ~/.node-red
npm install node-red-dashboard

2. Start Node-RED

Execute node-red on a console. The Node-RED administration interface should now be available on yournoderedhost:1880

Raspbian Tip

If you want Node-RED to automatically start on boot, execute:

sudo systemctl enable nodered.service

3. Paste the 102shows UI in Node-RED

Copy the contents of ui/nodered.json into the clipboard. Go to the Node-RED admin interface and in the main menu (upper right corner) choose Import >> Clipboard and paste the code you copied earlier into the window that is opening. Confirm with Import

You should now see the flow LED control.

Installing a development version

The link to ui/nodered.json above points to the latest stable version.

4. Configure the 102shows UI

In the upper left LED control there is a node named global settings. Double-click on it to open it and modify the preferences in the code so that they match the settings in your server-side

Save with Done and hit the red Deploy button on the upper right.

5. Have fun 😄

The UI is now available on yournoderedhost:1880/ui and you should be able to control your LED strips from there 👍



Give configuration advice



  1. Start the MQTT broker
  2. Execute /path/to/102shows/server/

Web UI

Just start Node-RED. The panel should appear on yournoderedhost:1880/ui
