  title: ecobee Authorization Thermostat API
  description: 'The ecobee API is a REST-like JSON interface for reading and controlling registered ecobee smart thermostats and connected home devices. The data plane is based at https://api.ecobee.com/1 and returns/accepts JSON. Read thermostat runtime, settings, sensors, and equipment status with GET /thermostat, poll for change efficiently with GET /thermostatSummary, and apply writable properties and thermostat functions with POST /thermostat. Historical data is available via GET /runtimeReport and GET /meterReport. Thermostats can be grouped (/group) and, for EMS and Utility accounts, organized in a management-set hierarchy (/hierarchy/*) and driven with demand response events (/demandResponse).

    Authorization uses OAuth 2.0 with an ecobee PIN flow or the standard authorization-code flow, plus refresh tokens; the OAuth endpoints (/authorize and /token) live on the host root https://api.ecobee.com (without the /1 path). All data-plane requests require an `Authorization: Bearer ACCESS_TOKEN` header.

    NOTE - as of late 2024, ecobee closed its developer program to new API-key registrations; existing keys continue to function. Endpoint shapes below are grounded in ecobee''s published v1 API documentation; request/response schemas are simplified models of the documented objects.'

      summary: Get thermostats
      description: Retrieves a selection of registered thermostats and their requested data (runtime, settings, program, events, alerts, sensors, and more). The Selection object in the `json` query parameter determines which thermostats and which sub-objects are returned.
      parameters:
      - name: json
        in: query
        required: true
        description: URL-encoded JSON request containing a `selection` object (and optional `page`) that determines the thermostats and data returned.

  /thermostatSummary:
    get:
      operationId: getThermostatSummary
      tags:
      - Thermostat
      summary: Get thermostat summary
      description: Returns a compact revision-list summary for the selected thermostats - thermostat id, name, connection status, and configuration/alert/runtime/ interval revision timestamps - so callers can detect changes without re-fetching full thermostat objects. Optionally includes equipment status. Poll no more frequently than once every three minutes.
      parameters:
      - name: json
        in: query
        required: true
        description: URL-encoded JSON request containing a `selection` object. Set `includeEquipmentStatus` to true to also receive equipment status.
