I created this utility to publish metrics from Teltonika gateways to InfluxDB v2 because the gateway required get commands to be sent to retrieve metrics.
Configuration is done through environment variables:
MQTT_USER=
MQTT_PASS=
MQTT_BROKER=
MQTT_TOPIC=
TELTONIKA_IP=
INFLUXDB_API_TOKEN=
INFLUXDB_URL=
INFLUXDB_ORG=
