Mycroft AI Skill

Mycroft AI is the world’s first open source voice enabled assistant. The skill allows you to connect a running Mycroft instance to your openHAB system. Supported natural voice commands and responses can freely be modified and extended.

The skill currently supportes the English (U.S.) and English (U.K.) languages but new languages are easily added via configuration files.

General Configuration Instructions

Requirements

  • A running instance of Mycroft (Mark 1, picroft, …)
  • A running instance of openHAB (version 1.x or v2.x)
  • openHAB must be reacheable from the Mycroft instance

Skill Installation

The openHAB skill has to be installed on your Mycroft instance, please refer to the official documentation to learn how to install a skill.

Clone the skill repository into the Mycroft skills directory, then trigger installation of needed dependencies:

cd ~/.mycroft/skills
git clone https://github.com/mortommy/mycroft-skill-openhab skill-openhab
workon mycroft
cd skill-openhab
pip install -r requirements.txt

If on picroft, use the skills directory /opt/mycroft/skills and skip the workon mycroft command.

Skill Configuration

Add the block below to your mycroft.conf file:

 "openHABSkill": {
        "host": "openHAB server ip",
        "port": "openHAB server port"
      }

Restart mycroft for the changes to take effect.

openHAB Item Configuration

Items are exposed to openHAB skill for Mycroft through the use of tags. See the Hue Emulation and HomeKit Add-on documentation for details about tagging and available tags.

  • Items via .items - File

    See Item Definition and Syntax

    Some examples of tagged items are:

    Color KitchenLight "Kitchen Light" <light> (gKitchen) ["Lighting"] {channel="hue:0200:1:bloom1:color"}
    Color DiningroomLight "Diningroom Light" <light> (gKitchen) ["Lighting"] {channel="hue:0200:1:bloom1:color"}
    Switch GoodNight "Good Night"	["Switchable"]	
    
    Number MqttID1Temperature "Bedroom Temperature" <temperature> ["CurrentTemperature"] {mqtt="<[mosquitto:mysensors/SI/1/1/1/0/0:state:default]"}
    Number MqttID1Humidity "Bedroom Humidity" ["CurrentHumidity"] {mqtt="<[mosquitto:mysensors/SI/1/0/1/0/1:state:default]"}
    
    Group gThermostat "Main Thermostat" ["gMainThermostat"]
    Number MainThermostatCurrentTemp "Main Thermostat Current Temperature" (gMainThermostat) ["CurrentTemperature"]
    Number MainThermostatTargetTemperature "Main Thermostat Target Temperature" (gMainThermostat) ["TargetTemperature"]
    String MainThermostatHeatingCoolingMode "Main Thermostat Heating/Cooling Mode" (gMainThermostat) ["homekit:HeatingCoolingMode"]
    

If items are modified in openHAB, a refresh in Mycroft is needed by the voice command:

  • “Hey Mycroft, refresh openHAB Items”

Item Label Recommendation

Matching of voice commands to Items happens based on the Item label (e.g. “Kitchen Light”). It is therefore advisable, to choose labels that can be used to form natural commands. As an example, compare “Hey Mycroft, turn on the Kitchen Light” vs. “Hey Mycroft, turn on the Ground Floor LEDs Kitchen”.

In combination with the Mycroft skill (and other similar services) you are thereby tempted to break with your naming scheme and introduce confusion into your setup. openHAB Tip: You may define multiple Items bound to one channel. Instead of manipulating the label of one single Item, you can define multiple Items specifically for voice commands. See the following example:

// Common/main Item bound to a binding channel
Switch Kitchen_Light    "Ground Floor LEDs Kitchen" <light> (gKitchen) {channel="..."}
// Two Items with labels fitting for voice commands, bound to the same binding channel
Switch Kitchen_Light_A  "Kitchen Light"                   ["Lighting"] {channel="..."}
Switch Kitchen_Light_A2 "Kitchen LEDs"                    ["Lighting"] {channel="..."}

Example Voice Commands

Each item tag supports different command, here is the summary:

Tag Key word Commands
Switchable turn on, off
  switch on, off
  put on, off
  what’s status
     
Lighting turn on, off
  switch on, off
  put on, off
  dim  
  dim by value in percentage
  brighten  
  brighten by value in percentage
     
Thermostat adjust to values in degrees
  regulate to values in degrees
  tune to values in degrees
  decrease by values in degrees
  increase by values in degrees
  what’s adjusted to
  what’s regulated to
  what’s tuned to
     
CurrentHumidity what’s humidity
     
CurrentTemperature what’s temperature

With references to the above item definitions, here are an examples of working commands:

  • “Hey Mycroft, turn on Diningroom Light”
  • “Hey Mycroft, switch off Kitchen Light”
  • “Hey Mycroft, put on Good Night”
  • “Hey Mycroft, what is Good Night status?”
  • “Hey Mycroft, set Diningroom to 50 percent”
  • “Hey Mycroft, dim Kitchen”
  • “Hey Mycroft, brighten Kitchen”
  • “Hey Mycroft, dim Kitchen by 20 percent”
  • “Hey Mycroft, what’s Bedroom temperature?”
  • “Hey Mycroft, what’s Bedroom humidity?”
  • “Hey Mycroft, adjust Main Thermostat to 21 degrees”
  • “Hey Mycroft, regulate Main Thermostat to 20 degrees”
  • “Hey Mycroft, decrease Main Thermostat by 2 degrees”
  • “Hey Mycroft, increase Main Thermostat by 1 degrees”
  • “Hey Mycroft, what is Main Thermostat regulated to?”
  • “Hey Mycroft, what is Main Thermostat tuned to?”

Additional Comments

  • By default all temperatures are in Celsius, no test so far about the tag Fahrenheit to the thermostat group item (which should also be tagged with Thermostat).
