Gem Version Build Status Test Coverage Code Climate Dependency Status


Huginn, which is Old Norse means "thought" and was one of Odin's ravens, is a pure Ruby implementation of the MQTT client protocol version 3.1.1.

Its main goals are:

  • high performance
  • concurrency

The current version should considered pre-alpha quality (i.e. it should probably not work). Meanwhile, take a look at the ruby-mqtt gem.
