Module: Trello

The Trello module displays all cards in a specific Trello list, in a style similar to the Newsfeed (showing one card at a time). Applications can be: displaying a TODO list, showing notes, or important information which needs to be shared between roommates.

Your card on Your card on the mirror


1. Execute the following commands from your MagicMirror/modules folder:

git clone # clone this repository
cd MMM-Trello # navigate into the folder
npm install # install dependencies

2. Add the module to your config/config.js file (see below for details).

Using the module

To use this module you will need a trello API Key, an access token, and your list identifier.

Get your required API Key and Token here, or see 'Configuration Options' for more details. Also find your list id as described here below Finding a List ID.

Then, add it to the modules array in the config/config.js file:

        module: 'MMM-Trello',
        position: 'bottom_center', // This can be any of the regions, best results in center regions.
        config: {
            // See 'Configuration options' for more information.
            api_key: "INSERT_YOUR_API_KEY",
            token: "INSERT_YOUR_TOKEN",
            list: "INSERT_YOUR_LIST_ID"

Finding a List ID

Copied from the Trello API docs:

One of the trickier parts of using the Trello API for simple use cases is finding a List ID that belongs to a user. There are a few ways of doing this depending on your skillsets. One such way is to use the Chrome Dev Tools to watch network traffic from the official client.

To try to make this easy, we'll be dumping the JSON from a known Card. Open the official Trello web client and find a Card from a list that you want to use as your target.

It should have a short URL that looks like Take that URL and add .json to the end as follows: Within the raw JSON dump you get when pulling up this new URL, you will see a field called idList.

Make sure you get the id after idList (use the search function of your browser - usually accessible with CTRL + F). The first id in the .json is not the id of the list you are searching for, it is the id of the card.


I have a weird error, what should I do?

Please check below if this is a known error, if not, feel free to post in the Troubleshooting Section of the Forum.

Error Possible Solution
Error 404(Not Found): model not found This can happen when you accidentally take the wrong id. Go through Finding a list id here again. Make sure to look for the cryptic number after idList, and do not take the first id (that is the card id) in the .json.
Error 400(api_key is empty) Enter your api_key (see Configuration Options).
Error 400(Bad Request) invalid id Your list id is not correct. Maybe you forgot a symbol?
Error 401(Unauthorized) unauthorized board permission requested Something is wrong with your token (see Configuration Options).
