Luis,
See enclosed.
You can use any variable by referencing the device id and the variable name.
You need to upgrade the MQTTBridge driver using the Force option on the properties page.
Thanks

You can publish messages to topics from my MQTT Bridge driver. The bridge needs to be registered to your MQTT broker, I use Mosquitto on a local Raspberry Pi but any platform will do, you could use AWS IoT services but then your going out to the Internet etc.
Once the bridge is setup and logged into a broker you can publish messages from programming, I have enclosed screenshots.
If on the other hand you would like to write your own Control4 drivers to interface with my MQTT Bridge then I can send you a sample driver that links to the bridge.
Thanks
David
