Wireless end nodes (RFM69 based) are connected to a central gateway that speaks MQTT to a Mosquitto message broker. The gateway acts as a radiohub for the end nodes. It translates and parses MQTT messages and controls the end nodes. Traffic is duplex. This means every write command to the node is acknowledged. Actuators (LED, relay) on the end node can be controlled over MQTT. The end node is configurable via MQTT and will periodically send sensor data to the gateway. Sensor data can also be queried by MQTT. This is a working setup in development. Sensor and gateway are Arduino based. Software and schematics can be found at: https://github.com/computourist/RFM69-MQTT-client
