I intend to use TimescaleDB (+PostGIS) for all other data and last year researched this approach for the raw sensor data. I think they have improved compression since then.
For my use, the raw sensor data should only be retrieved 1) to perform a windowed analysis (the results of which will be stored in PostgreSQL) or 2) to display for the user. I'm planning to archive the raw sensor data in files for archival, so I think it's easier to just jam the data in 15-minute netCDF files and call it a day. Will definitely keep an open mind.
