For transparency, here is a live snapshot of approximately one day of Fleet API usage and cost for
@Teslascope before any optimizations.
Before expenses, this is about 80% of Teslascope's monthly revenue in just one day, so we'll surpass this after tomorrow's usage. In total, this adds up to 24x our current monthly revenue. Teslascope is not the most prominent Tesla third party, with some app usage costs approaching 50x their revenue.
Switching to Fleet Telemetry without any feature reduction would cost approximately ~$350/day, which is still 3.5-7x our monthly revenue and still not sustainable.
We have discussed setting a limit on the hours of charging/driving session recording per month, which currently appears to be mandatory to keep costs per vehicle reasonable. As such, we plan to switch to per-vehicle pricing (at $3.99 and $5.99, respectively); however, this would still barely cover the API fees without considering infrastructural costs or my livelihood (profit).
If we removed non-paid vehicle access (which already has significantly reduced polling/session recording), we'd still be well above our revenue (~3.0-6.3x).
This post aims to illustrate third-party developers' concerns and why we're praying for an agreeable solution that works for everyone to ensure survivability and financial viability going forward.
