Did anyone already try the AT&T M2X add-on on Heroku to stream data which are then processed with a Dash app on Heroku?
I’ve explored the Google Drive option, but my Arduino Yun (still running Python 2.7) can not manage the apiclient module which I successfully used on my desktop to send csv’s to the cloud (i/o streaming data).
I stream my sensor data on a per-event basis (every few minutes) directly to dynamodb on aws using boto3. The dynamodb table is set up with sensor id as the hash key and timestamp ts as the sort key. That allows me to query for any sensor data with ts > provided date. I haven’t run into any issues with read/write capacity or storage in the free tier.
NoSQL worked for me because my sensors may have different schemas (some sensors return multiple values, for example). May be easier to use something like AWS RDS instead of dynamo.
