Set HVAC and fan mode settings

Learn about how to configure the current climate settings on a thermostat.
Overview
Seam allows you to adjust the current heating and cooling settings, and the fan mode of a thermostat. This guide will walk you through how to do this with the API.
When you send a command to change a setting, it might take a while for Seam to confirm the action's success. To handle this, Seam provides an "action attempt" object, which indicates whether the action was successful.
To ensure that the action has been successfully executed, we advise checking the status of the action attempt object by polling the "Get Action Attempt" request. Once Seam has successfully adjusted the thermostat setting, the action attempt's status will indicate success.
For those who prefer using webhooks to verify the success of an action, we'll soon introduce events that indicate changes to the thermostat's climate settings.
Verifying that an thermostat setting action has succeeded
1. Execute a "Heat" request (or other mode setting action)
When initiating a change in the thermostat settings, the Seam API returns an action attempt, which monitors the success or failure of the action.

Second Tab
Request:
curl --request POST "https://connect.getseam.com/thermostats/heat" \
--header "Authorization: Bearer ${API_KEY}" \
--header "Content-Type: application/json" \
--header "Seam-Workspace: ${WORKSPACE_ID}" \
--data-raw "{
  \"device_id\": \"${DEVICE_ID}\",
  \"heating_set_point_celsius\": 25
}"
Response:
{
  "action_attempt": {
    "status": "pending",
    "action_type": "SET_HEAT",
    "action_attempt_id": "00000000-0000-0000-0000-000000000000",
    "result": null,
    "error": null
  },
  "ok": true
}
​
2. Poll the "Get Action Attempt" request to verify the setting change
Use the action_attempt_id from the prior response to make a Get Action Attempt request. When the action attempt's status changes to success, it indicates the setting modification has been successful.
Curl
Request:
curl --silent --request GET "https://connect.getseam.com/action_attempts/get" \
    --header "Authorization: Bearer ${API_KEY}" \
    --header "Content-Type: application/json" \
    --header "Seam-Workspace: ${WORKSPACE_ID}" \
    --data-raw "{\"action_attempt_id\": \"$action_attempt_id\"}"
Response:
{
  "action_attempt": {
    "status": "success",
    "action_type": "SET_HEAT",
    "action_attempt_id": "00000000-0000-0000-0000-000000000000",
    "result": null,
    "error": null
  },
  "ok": true
}
Set to Heat Mode
You can set a thermostat to operate in heating mode and specify a desired temperature. By establishing the set point, the thermostat will activate its heating system to maintain the specified  temperature.
Set the HVAC Mode to heat by providing the device_id of the thermostat and the "heating set point" in Celsius or Fahrenheit.

    "result": null,
    "error": null
  },
  "ok": true
}
Set to Cool Mode
You can set a thermostat to operate in cooling mode and specify a desired temperature. By establishing the set point, the thermostat will activate its cooling system to maintain the specified  temperature.
Set the HVAC Mode to cool by providing the device_id of the thermostat and the "cooling set point" in Celsius or Fahrenheit.

curl --request POST 'https://connect.getseam.com/thermostats/cool' \
--header 'Authorization: Bearer ${API_KEY}' \

Response:
{
  "action_attempt": {
    "status": "pending",
    "action_type": "SET_COOL",
    "action_attempt_id": "22222222-2222-2222-2222-222222222222",
    "result": null,
    "error": null
  },
  "ok": true
}
Set to Heat-Cool Mode
You can set a thermostat to operate in heat-cool (or "auto") mode and specify desired temperatures for both heating and cooling. By establishing the set points, the thermostat will activate its systems as needed to maintain the specified temperature range.
Set the HVAC Mode to heat_cool by providing the device_id of the thermostat and both the "heating set point" and "cooling set point" in Celsius or Fahrenheit.

Turn off heating and cooling
You can set a thermostat to operate in "off" mode, which deactivates its heating and cooling systems. In this state, the thermostat will not regulate indoor temperatures.
Set the HVAC Mode to off by providing the device_id of the thermostat.

    "result": null,
    "error": null
  },
  "ok": true
}
Set the Fan Mode
You can configure a thermostat's fan to operate in either on or auto mode. In the "on" setting, the fan runs continuously, while in "auto" mode, the fan operates based on temperature needs and system demands.
Set the Fan Mode by providing the device_id of the thermostat and specifying the desired fan setting.
