API for ClimaSense IoT devices to report telemetry, receive commands, and manage firmware updates.

Authentication

All endpoints require API key authentication via the Authorization header:

Authorization: Bearer <api_key>

API keys are provisioned during device manufacturing and stored hashed on the server.

Rate Limits

Endpoint Limit Window
POST /v1/telemetry 60 requests 1 minute
GET /v1/settings 10 requests 1 minute
GET /v1/commands/pending 30 requests 1 minute
GET /v1/ota/check 10 requests 1 minute

Telemetry

Sensor data ingestion

Submit sensor readings

Submit one or more sensor readings from the device. Readings are stored in TimescaleDB and routed to the alert evaluation system.

Sensor Types:

  • temperature (°C)
  • humidity (%)
  • pressure (hPa)
  • power_availability (boolean as 0/1)
  • battery_level (%)
  • signal_strength (dBm)
  • iaq (Indoor Air Quality index)
