thingsboard-gateway

Gateway to connect BLE sensors to Thingsboard. BLE sensors are detected via Eddystene Beacon-URI. The data is processed and formed into a JSON file compatible with the Thingsboard MQTT Gateway API.

Installation

The python script is based on the BlueZ D-Bus API. It prints the JSON data to stdout and debug information to stderr. The following commands executes the script pipes the output from stdout to data.out, it pipes the debug information from stderr to ts which creates a timestamp and finally stores the logging information in gateway.log.

$ ./gateway.py 2>&1 >> data.out | ts "%Y-%m-%d %T" >> gateway.log

The content from data.out is piped to mosquitto_pub to transfer the data to a MQTT broker. The log output is piped to ts and stored in mosquitto_pub.log.

mosquitto_pub -d -h "${MQTT_HOST}" -p "${MQTT_PORT}" -t "${MQTT_TOPIC}" -u "${MQTT_USER}" -l < data.out 2>&1 | ts "%Y-%m-%d %T" >> mosquitto_pub.log
