telemetry.telemetry: All time-series data is stored in this table. Sources are:

• AQ&U: AirU sensors publish data to a Mosquitto MQTT broker hosted at air.eng.utah.edu at the University of Utah. A service located at /home/becnel/aqandu-prod-mosquitto-bq-bridge on the same server listens to the topic airu/influx, ingests incoming data, and forwards it to telemetry.telemetry.
