At the site-level, every point is logged and stored short-term in a SQLite database on the Turntide Hub. There is the capability to securely export this local data directly from the hub as a CSV.
The same data is also pushed to the cloud where we do long-term data storage. All values are stored from the time the system is installed and is never thrown away. Data across all your sites can be accessed in the Turntide Cloud Application or directly via our REST API.
There are two options to retrieve historical data:
- Use charting to export the desired data as CSV.
- Use the history API to get historical data formatted as JSON.
