# osc-mqtt-bridge
|
|
A bridge between [Open Sound Control](https://en.wikipedia.org/wiki/Open_Sound_Control) (OSC) and MQTT, allowind bidirectional communication. The main purpose of this tool is to provide a way to talk to devices that support OSC via MQTT messages for automation.
|
|
|
|
## Example configuration
|
|
```yaml
|
|
relays:
|
|
- mqtt_host: 10.0.0.2
|
|
mqtt_port: 1883
|
|
mqtt_client_id: osc_mqtt_bridge
|
|
mqtt_user: mqtt
|
|
mqtt_password: PASSWORD
|
|
mqtt_topic: osc/behringer_wing
|
|
osc_host: 10.0.0.3
|
|
osc_port: 2223
|
|
osc_bind_addr: 10.0.0.4 # Change to this machine's IP address. Expected to be a static IP.
|
|
log_level: 2
|
|
```
|
|
|
|
## Configuration specification
|
|
|
|
### Relay
|
|
- `mqtt_host`: Hostname of the MQTT broker.
|
|
- `mqtt_port`: Port of the MQTT broker.
|
|
- `mqtt_client_id`: MQTT client ID of this relay.
|
|
- `mqtt_user`: User name used for MQTT authentication.
|
|
- `mqtt_password`: Password used for MQTT authentication.
|
|
- `mqtt_topic`: Topic where MQTT messages are pushed and received.
|
|
|
|
Set topic to `osc/example` and the following topics will be setup.
|
|
- `osc/example/cmd/$OSC_CMD` - Any commands received on OSC will publish here.
|
|
- `osc/example/send/$OSC_CMD` - Any commands pushed via MQTT will be forwarded to OSC.
|
|
- `osc/example/bundle` - OSC Bundle messages.
|
|
- `osc/example/bundle/send` - Send OSC Bundle messages.
|
|
- `osc/example/status` - Configuration is published on startup.
|
|
- `osc/example/status/check` - Request status.
|
|
<br/><br/>
|
|
|
|
- `mqtt_disable_config_send`: Disables the config send.
|
|
- `osc_host`: Hostname for OSC client connection.
|
|
- `osc_port`: Port for OSC client connection.
|
|
- `osc_bind_addr`: Bind address of the OSC server.
|
|
|
|
To have bidirectional mode, you must specify at least this, OscHost, and OscPort defined. You must specify the unicast IP address, cannot be `0.0.0.0`.
|
|
|
|
- `osc_bind_port`: Port of the OSC server. Defaults to OscPort if specified.
|
|
- `osc_disallow_arbritary_command`: Disallows pushing to arbritary commands to the cmd topic.
|
|
- `commands`: Pre-defined commands to relay.
|
|
|
|
This is an array with the following variables.
|
|
|
|
- `command`: The command path to send.
|
|
- `mqtt_topic`: Absolute MQTT topic to subscribe.
|
|
- `mqtt_sub_topic`: Sub topic off relay MQTT topic to subscribe.
|
|
osc/example/$SUB_TOPIC
|
|
- `disallow_payload`: Rather or not to disallow payload to be relayed.
|
|
- `default_payload`: Payload to send if no payload is provided via MQTT or if DisallowPayload is true. This is an array of strings/integers/timestamps/bools.
|
|
<br/><br/>
|
|
|
|
- `osc_subscriptions`: OSC Comamnds to send at regular intervals. Useful for OSC servers that offers data subscriptions.
|
|
|
|
This is an array with the following variables.
|
|
|
|
- `command`: The command to send every interval.
|
|
- `payload`: Payload to send. This is an array of strings/integers/timestamps/bools.
|
|
- `interval`: How often to call the command.
|
|
<br/><br/>
|
|
|
|
- `log_level`: How much logging.
|
|
|
|
- 0 - Errors
|
|
- 1 - MQTT and OSC receive logging.
|
|
- 2 - MQTT and OSC send logging.
|
|
- 3 - Debug
|
|
