What is Huginn?

Huginn is a system for building agents that perform automated tasks for you online. They can read the web, watch for events, and take actions on your behalf. Huginn's Agents create and consume events, propagating them along a directed graph. Think of it as a hackable version of IFTTT or Zapier on your own server. You always know who has your data. You do.

Here are some of the things that you can do with Huginn:

• Track the weather and get an email when it's going to rain (or snow) tomorrow ("Don't forget your umbrella!")
• List terms that you care about and receive email when their occurrence on Twitter changes. (For example, want to know when something interesting has happened in the world of Machine Learning? Huginn will watch the term "machine learning" on Twitter and tell you when there is a spike in discussion.)
• Watch for air travel or shopping deals
• Follow your project names on Twitter and get updates when people mention them
• Scrape websites and receive email when they change
• Connect to Adioso, HipChat, Basecamp, Growl, FTP, IMAP, Jabber, JIRA, MQTT, nextbus, Pushbullet, Pushover, RSS, Bash, Slack, StubHub, translation APIs, Twilio, Twitter, Wunderground, and Weibo, to name a few.
• Send digest email with things that you care about at specific times during the day
• Track counts of high frequency events and send an SMS within moments when they spike, such as the term "san francisco emergency"
• Send and receive WebHooks
• Run custom JavaScript or CoffeeScript functions
• Track your location over time
• Create Amazon Mechanical Turk workflows as the inputs, or outputs, of agents (the Amazon Turk Agent is called the "HumanTaskAgent"). For example: "Once a day, ask 5 people for a funny cat photo; send the results to 5 more people to be rated; send the top-rated photo to 5 people for a funny caption; send to 5 final people to rate for funniest caption; finally, post the best captioned photo on my blog."

Examples

Please checkout the Huginn Introductory Screencast!

And now, some example screenshots. Below them are instructions to get you started.

Getting Started

Docker

The quickest and easiest way to check out Huginn is to use the official Docker image. Have a look at the documentation.

Local Installation

If you just want to play around, you can simply fork this repository, then perform the following steps:

• Run git remote add upstream https://github.com/huginn/huginn.git to add the main repository as a remote for your fork.
• Copy .env.example to .env (cp .env.example .env) and edit .env, at least updating the APP_SECRET_TOKEN variable.
• Make sure that you have MySQL or PostgreSQL installed. (On a Mac, the easiest way is with Homebrew. If you're going to use PostgreSQL, you'll need to prepend all commands below with DATABASE_ADAPTER=postgresql.)
• Run bundle to install dependencies
• Run bundle exec rake db:create, bundle exec rake db:migrate, and then bundle exec rake db:seed to create a development database with some example Agents.
• Run bundle exec foreman start, visit http://localhost:3000/, and login with the username of admin and the password of password.
• Setup some Agents!
• Read the wiki for usage examples and to get started making new Agents.
• Periodically run git fetch upstream and then git checkout master && git merge upstream/master to merge in the newest version of Huginn.

Note: By default, email messages are intercepted in the development Rails environment, which is what you just setup. You can view them at http://localhost:3000/letter_opener. If you'd like to send real email via SMTP when playing with Huginn locally, set SEND_EMAIL_IN_DEVELOPMENT to true in your .env file.

If you need more detailed instructions, see the Novice setup guide.

Develop

All agents have specs! And there's also acceptance tests that simulate running Huginn in a headless browser.

• Install PhantomJS 2.1.1 or greater:
  • Using Node Package Manager: npm install phantomjs
  • Using Homebrew on OSX brew install phantomjs
• Run all specs with bundle exec rspec
• Run a specific spec with bundle exec rspec path/to/specific/test_spec.rb.
• Read more about rspec for rails here.

Using Huginn Agent gems

Huginn Agents can now be written as external gems and be added to your Huginn installation with the ADDITIONAL_GEMS environment variable. See the Additional Agent gems section of .env.example for more information.

If you'd like to write your own Huginn Agent Gem, please see huginn_agent.

Our general intention is to encourage complex and specific Agents to be written as Gems, while continuing to add new general-purpose Agents to the core Huginn repository.

Deployment

Please see the Huginn Wiki for detailed deployment strategies for different providers.

Heroku

Try Huginn on Heroku: (Takes a few minutes to setup. Read the documentation while you are waiting and be sure to click 'View it' after launch!)

Huginn launches on the free version of Heroku with significant limitations. For non-experimental use, we strongly recommend Heroku's 1GB paid plan or our Docker container.

OpenShift

OpenShift Online

Try Huginn on OpenShift Online

Create a new app with either mysql or postgres:

oc new-app -f https://raw.githubusercontent.com/huginn/huginn/master/openshift/templates/huginn-mysql.json

or

oc new-app -f https://raw.githubusercontent.com/huginn/huginn/master/openshift/templates/huginn-postgresql.json

Note: You can also use the web console to import either json file by going to "Add to Project" -> "Import YAML/JSON".

If you are on the Starter plan, make sure to follow the guide to remove any existing application.

The templates should work on a v3 installation or the current v4 online.

Manual installation on any server

Have a look at the installation guide.

Optional Setup

Setup for private development

See private development instructions on the wiki.

Enable the WeatherAgent

In order to use the WeatherAgent you need an API key with Wunderground. Signup for one and then change the value of api_key: your-key in your seeded WeatherAgent.

Note, Wunderground no longer offers free API keys. You can still use the WeatherAgent by setting the service key to darksky, and getting an API key from DarkSky.

Disable SSL

We assume your deployment will run over SSL. This is a very good idea! However, if you wish to turn this off, you'll probably need to edit config/initializers/devise.rb and modify the line containing config.rememberable_options = { :secure => true }. You will also need to edit config/environments/production.rb and modify the value of config.force_ssl.
