# Mycroft Binding

This binding connects to Mycroft A.I. in order to control it or react to events by listening on the message bus.

Possibilies include:

  • Press a button in openHAB to wake Mycroft without using a wake word.
  • Simulate a voice command to launch a skill, as if you just spoke it
  • Send some text that Mycroft will say (Using its Text To Speech service)
  • Control the music player
  • Mute the sound volume of Mycroft
  • React to all the aforementioned events ...
  • ... and send/receive any other kind of messages on the message bus

# Supported Things

The only thing managed by this binding is a Mycroft instance
