+# 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
+
+|   Thing Type ID    |            Description                                                     |
+|--------------------|----------------------------------------------------------------------------|
+|   mycroft          |    A Mark I/II, a Picroft, or any other variant exposing the message bus   |
+
+
+
+## Discovery
+
+There is no discovery service, as Mycroft doesn't announce itself on the network.
+
+
+## Thing Configuration
+
+The configuration is simple, as you just need to give the IP/hostname of the Mycroft instance accessible on the network.
+The default port is 8181, which can be changed.
+
+```
+Thing mycroft:mycroft:myMycroft "Mycroft A.I." @ "Living Room" [host="192.168.X.X"]
+```
+
+|   property               |         type           |         description                                              | mandatory |
+|--------------------------|------------------------|------------------------------------------------------------------|-----------|
+| host                     | IP or string           | IP address or hostname                                           |   Yes     |
+| port                     | integer                | Port to reach Mycroft (default 8181)                             |   No      |
+| volume_restoration_level | integer                | When unmuted, force Mycroft to restore volume to this value      |   No      |
+
+
+## Channels
+
+A Mycroft thing has the following channels:
+
+
+| channel type id              | Item type | description                                                                                    |
+|------------------------------|-----------|------------------------------------------------------------------------------------------------|
+| listen                       | Switch    | Switch to ON when Mycroft is listening. Can simulate a wake word detection to trigger the STT  |
+| speak                        | String    | The last sentence Mycroft speaks                                                               |
+| utterance                    | String    | The last utterance Mycroft receive                                                             |
+| player                       | Player    | The music player Mycroft is currently controlling                                              |
+| volume_mute                  | Switch    | Mute the Mycroft speaker                                                                       |
+| volume                       | Dimmer    | The volume of the Mycroft speaker. (Note : Value unreliable until a volume change occured)     |
+| full_message                 | String    | The last message (full json) seen on the Mycroft Bus. Filtered by the messageTypes properties  |
+
+
+The channel 'full_message' has the following configuration available:
+
+| property      |  type                           | description                                                             | mandatory |
+|---------------|---------------------------------|-------------------------------------------------------------------------|-----------|
+| messageTypes  | List of string, comma separated | Only these message types will be forwarded to the Full Message Channel  |   No      |
+
+
+## Full Example
+
+A manual setup through a `things/mycroft.things` file could look like this:
+
+```java
+Thing mycroft:mycroft:myMycroft "Mycroft A.I." @ "Living Room" [host="192.168.X.X", port=8181] { 
+    Channels:
+        Type full-message-channel : Text [
+            messageTypes="message.type.1,message.type.4"
+        ]
+}
+```
+
+### Item Configuration
+
+The `mycroft.item` file:
+
+```java
+Switch myMycroft_mute                  "Mute"                      { channel="mycroft:mycroft:myMycroft:volume_mute" }
+Dimmer myMycroft_volume                "Volume [%d]"               { channel="mycroft:mycroft:myMycroft:volume" }
+Player myMycroft_player                "Control"                   { channel="mycroft:mycroft:myMycroft:player" }
+Switch myMycroft_listen                "Wake and listen"           { channel="mycroft:mycroft:myMycroft:listen" }
+String myMycroft_speak                 "Speak STT"                 { channel="mycroft:mycroft:myMycroft:speak" }
+String myMycroft_utterance             "Utterance"                 { channel="mycroft:mycroft:myMycroft:utterance" }
+String myMycroft_fullmessage           "Full JSON message"         { channel="mycroft:mycroft:myMycroft:full_message" }
+```
+
+### Sitemap Configuration
+
+A `demo.sitemap` file:
+
+```
+sitemap demo label="myMycroft"
+{
+    Frame label="myMycroft" {
+        Switch    item=myMycroft_mute
+        Slider    item=myMycroft_volume
+        Default   item=myMycroft_player
+        Switch    item=myMycroft_listen
+        Text      item=myMycroft_speak
+        Text      item=myMycroft_utterance
+        Text      item=myMycroft_fullmessage
+    }
+}
+```
+
+
+### Ask Mycroft to say something
+
+mycroft.rules
+
+```java
+rule "Say Hello"
+when
+   Item Presence_Isaac changed
+then
+   myMycroft_speak.sendCommand("Hello Isaac")
+end
+```
