InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Use this type of sensor and hook it up to the Raspberry rather than to the printer. It's much easier and there's no firmware flashing involved. Also, if you print from Octoprint you must connect it to the Raspberry anyway, otherwise Octoprint would not know when the filament runs out.
