Hello @Daly,
Welcome to the HiveMQ Community Forum! We’re glad to see your interest in MQTT and HiveMQ.
While we don’t have an example that exactly matches your specific requirements, we do have a useful example on integrating HiveMQ with ESP32 and Node-RED, which you can find here: HiveMQ using ESP32 and Node-RED. We recommend checking it out, as it may serve as a helpful starting point for your project.
Regards,
Sheetal from HiveMQ Team
