To ensure long-term stability while continuing to allow access to our REST API, we have implemented the following limits:
100 requests / day
This should still support basic use cases that are not available via tado’s local APIs: HomeKit for V3/V3+ devices or Matter for tado° X devices.
For Auto-Assist subscribers: 20.000 requests / day
This should cover even more demanding use cases, and the subscription fees enable us to offset the increased costs associated with additional server calls.
While never officially supported for third parties, we’ve historically left our REST API open and unrestricted. We believe in fair use, and we intend to continue supporting that principle.
Our involvement in implementing this limitation is an exceptional need, as we have experienced a small fraction of very frequent API users creating a disproportionately high share of our server expenses.
