🤖 Persona Integration

The project also includes the ovos-solver-bus-plugin, a plugin for interacting with ovos-core wherever a solver can be used.

example persona.json

{
  "name": "Open Voice OS",
  "solvers": [
    "ovos-solver-bus-plugin",
    "ovos-solver-failure-plugin"
  ],
  "ovos-solver-bus-plugin": {
    "autoconnect": true,
    "host": "192.168.1.200",
    "port": 8181
  }
}

Use Cases:

• Expose ovos-core to any OpenAI-compatible project via ovos-persona-server
  • Chat with OVOS via the Open Web UI
  • Expose OVOS as an agent for Home Assistant
• Integrate OpenVoiceOS into a Mixture Of Solvers (MOS)

🐍 Python Usage

MycroftBusClient()

The MycroftBusClient() object can be setup to connect to any host and port as well as any endpont on that host. this makes it quite versitile and will work on the main bus as well as on a gui bus. If no arguments are provided it will try to connect to a local instance of OVOS on the default endpoint and port.

NOTE: we kept the original pre-fork class name for compatibility reasons

Message()

The Message object is a representation of the messagebus message, this will always contain a message type but can also contain data and context. Data is usually real information while the context typically contain information on where the message originated or who the intended recipient is.

Message('MESSAGE_TYPE', data={'meaning': 42}, context={'origin': 'A.Dent'})

Examples

Below are some a couple of simple cases for sending a message on the bus as well as reacting to messages on the bus

Sending a message on the bus.

from ovos_bus_client import MessageBusClient, Message

print('Setting up client to connect to a local OVOS instance')
client = MessageBusClient()
client.run_in_thread()

print('Sending speak message...')
client.emit(Message('speak', data={'utterance': 'Hello World'}))

Catching a message on the messagebus

from ovos_bus_client import MessageBusClient, Message

print('Setting up client to connect to a local OVOS instance')
client = MessageBusClient()

def print_utterance(message):
    print('OVOS said "{}"'.format(message.data.get('utterance')))


print('Registering handler for speak message...')
client.on('speak', print_utterance)

client.run_forever()
