This guide shows you how to display a Trello board/dashboard on your digital signage screens using Pickcel, which is excellent for visualizing workflows, tracking task progress, and managing team projects in a shared space.

Prerequisites

• An Atlassian account with access to the target Trello board.
• Email and password login available for that account.
• 2‑Factor Authentication (2FA) enabled on the account, with the 2FA secret key available.
• The full Trello board/dasboard URL you plan to display

See our guide: How to Set Up 2FA and Get a Secret Key.

This integration requires a direct Atlassian account login with an email and password. Federated login methods, such as signing in with a Google, Microsoft, or Apple account, are not compatible with this setup. Please ensure you use an account with basic authentication credentials.

Best Practice
For enhanced security and easier management, create a dedicated service account in Atlassian with read-only permissions for the Trello board you want to display. Use this account's credentials for Pickcel.

Step-by-Step Configuration:

1. Create the Dashboard App in Pickcel:

1. Log in to the Pickcel Console and navigate to Apps. Search for the Dashboard app and click on it. Then, click Create App.
   
   
   
2. Give a name to the app instance based on the board you are configuring (e.g., "Project Phoenix Trello Board").
   
   
3. Now, select Trello from the dropdown menu. The configuration fields will open on the right.
   
   
   

2. Fill in the Fields for Trello Dashboard Configuration:

This section requires precise information to generate a correct and secure Auth Token.

1. Atlassian Login URL: Log out of Trello. Go to the Trello login page. Copy the entire URL from your browser's address bar and paste it here.
   
   
   
   
2. Atlassian Email ID: Enter the email address for your Atlassian Account.
   
   
3. Atlassian Password: Enter the password for that account.
   
   
4. Auth Secret Key: Paste the 2FA Secret Key you saved when setting up 2FA for the Atlassian account.
   
   
5. Trello Board/Dashboard URL: Log back into Trello and navigate to the exact board you want to display. Copy the entire URL from the address bar and paste it here.
   
   
   
   
   
6. Click Generate Auth Token. The token will be generated and automatically pasted into the Auth Token field on the left, as shown below.
   
   

1. Enter Screen Selection Code (Optional): To display only specific lists on your board, use the Pickcel Dashboard Screen Mapper Extension. Select the area, and the generated code will be copied to your clipboard. Paste this code into the Screen Selection Code field.

3. Set Refresh Interval and Session Expiry:

• Refresh Interval: This setting defines how often the board screenshot is updated. An interval of 15 minutes is a good starting point for most Trello boards. This means the signage screen will display a fresh view of your board every 15 minutes.

• Session Expiry: This forces a fresh login to prevent session timeouts from the service provider. A value of 5-8 hours is recommended.
  
  

4. Enable Scroll Option for the Board:

There are two ways to scroll through your entire board:

• Enable Auto Scroll: This lets you set a scroll duration in seconds. For example, if you set it to 20 seconds, the entire board will scroll from top to bottom over 20 seconds.
• Enable Auto Scroll Height: This lets you set a scroll height in pixels. The screen will scroll down by the defined pixel height.
  
  

5. Create and Publish:

• Once you are done with the configuration, click Create App. This successfully creates the app instance, which will be available to view in the Media section.
  
  

• To preview the board, go to Media, find the app instance by the name you created (e.g., "Project Phoenix Trello Board"), and click on its thumbnail (magnifier icon). This will display a preview. If you are content with the result, assign it to your digital signage screens.
  
  

Here's the preview:

1. The output is visible as a preview in the media section as shown above. It may take some time for the board screenshot to load, depending on the complexity of the board.
2. If the password or any other credentials are incorrect, the process will stall on the login screen, displaying the login screen instead of the board.

That's a wrap! 🎉
