Hi
I have a barometric sensor arduino project that logs the humidity, pressure and temperature readings to a cloud database (influxdb). Soon I will add other metrics like for example GPS, battery power data to my set-up as well (my set up is similar to this).
So I would like to import the data into HA and create a dashboard showing this data. Maybe later create an automation based on the data.
I was searching for an InfluxDB integration but these are all about storing HA data to a locally running Influxdb, not the other way around: reading data from an cloud influxdb.
Can anyone point me an example on how to read data from a cloud database?
many thanks! 
P.S. these pages indicate how to read data from influxdb.
