the EventHubApp developed by Dave Lusty from Microsoft UK sends sensor data from a Garmin watch over the Microsoft Azure Cloud to Microsoft Power BI. Unfortunately, there is hardly any support to send Garmin sensor data to Matlab or Python. Rewiring the of the EventHubApp to send sensor data to an MQTT broker could solve the problem, to have support for InfluxDB, Grafana, Matlab and Python. There is already a Garmin connect IQ app with MQTT support, but unfortunately only for SmartHomeNG:
