Origami Hue Example App

Origami Hue Example App.origami is an Origami prototype that turns a Hue light on and off.

Requests from the prototype to Hue have to go through a proxy, index.js, so they can be correctly formatted. Origami doesn’t yet have fine-grained control over request headers and methods.

The proxy in this repo uses Node and Express, and it expects a request body like this, which is what Origami sends:

{ '{
  "uri": "https://api.meethue.com/bridge/<whitelist-id>/lights/1/state",
  "method": "PUT",
  "headers": {
    "Authorization": "Bearer <access-token>",
    "Content-Type": "application/json"
  },
  "body": {
    "on": 1,
    "bri": 200
  }
}' : '' }

Getting started

To run the server, run yarn start or node index.js from the project folder. The server should start at http://localhost:3000.

In the Origami prototype, make the following changes to send a real request:

  • Edit the “Default Body” splitter patch to include your own whitelist id, access token, and light id.
  • If you’re not running the proxy at http://localhost:3000, edit the “Proxy Host” splitter patch to your new proxy url.


Using with Origami Live

Origami Live can’t connect to your localhost, so you need to run this proxy server from a domain. Creating a Heroku app is the easiest way to do this:

  • Create a Heroku account if you don’t have one.
  • From the /apps dashboard, create a new app.
  • In the app’s settings tab, add the heroku/nodejs buildpack.
  • Push the proxy code to the new app. Connecting Heroku to Github makes this easy.
  • Copy the Heroku domain e.g. https://your-app.herokuapp.com into the “Proxy Host” splitter patch in Origami.
  • Load the prototype onto your phone, disconnect, and enjoy!

Getting an access token and whitelist id from Hue

Create a Hue developer account if you don’t have one, then create an app and follow these steps:

  1. Navigate to a url like this, but with your own client id and app name. Login to your Hue account and approve access to your new Hue app. You’ll be redirected to your app’s callback url, with a query param containing a short code that you’ll use for the next step.
https://api.meethue.com/oauth2/auth?clientid=<your-client-id>&response_type=code&state=abc&deviceid=<your-device-id>&appid=<your-app-name>
  1. Make a POST request to the following url, replacing the code with your own, and using an Authorization token that’s a base64 encoded string of your app’s id and secret e.g. base64(clientid:clientsecret). You’ll receive a response containing an access token.
echo -n clientid:clientsecret | openssl base64
curl -X POST \
  'https://api.meethue.com/oauth2/token?code=<your-code>&grant_type=authorization_code' \
  -H 'Authorization: Basic <your-token>' \

  1. Make a PUT request to the following url, replacing the access token with your own. Proceed immediately to the next step.
curl -X PUT \
  https://api.meethue.com/bridge/0/config \
  -H 'Authorization: Bearer <your-access-token>' \
  -H 'Content-Type: application/json' \
  -d '{ "linkbutton": true }'
  1. Make a POST request to the following url, replacing the access token and app name with your own. You’ll receive a response containing a whitelist id.
curl -X POST \
  https://api.meethue.com/bridge \
  -H 'Authorization: Bearer <your-access-token>' \
  -H 'Content-Type: application/json' \
  -d '{ "devicetype": "<your-app-name>" }'
