Google assistant temperature setting active thermostat mode by lucsansag · Pull Request #166448 · home-assistant/core

lucsansag · 2026-03-25T07:41:27Z

Proposed change

The integration was previously setting only thermostatMode but not
activeThermostatMode, resulting in the Google Home UI not showing
whether a thermostat was actually heating/cooling, etc., or idle.
Map HVACAction values to Google modes and return the current one as
activeThermostatMode.

Pull request overview

This PR updates the Google Assistant TemperatureSettingTrait to report the thermostat’s current activity (heating/cooling/idle) via activeThermostatMode, improving the Google Home UI’s ability to show whether the device is actively running.

Changes:

Add an HVAC action → Google mode mapping and expose it as activeThermostatMode in query responses.
Add a unit test validating activeThermostatMode for idle and cooling actions.

File	Description
`homeassistant/components/google_assistant/trait.py`	Adds `activeThermostatMode` based on `climate.ATTR_HVAC_ACTION`.
`tests/components/google_assistant/test_trait.py`	Adds a test to validate `activeThermostatMode` output.

+        climate.HVACAction.FAN: "fan-only",
+        climate.HVACAction.IDLE: "none",


Map all Home Assistant HVACAction values to avoid dropping activeThermostatMode for valid actions like DEFROSTING and PREHEATING (currently unmapped, so the key is omitted when those actions occur).

Suggested change

climate.HVACAction.IDLE: "none",

climate.HVACAction.IDLE: "none",

climate.HVACAction.PREHEATING: "heat",

climate.HVACAction.DEFROSTING: "heat",

Expand the test coverage to assert activeThermostatMode for the other mapped actions (e.g., HEATING, DRYING, FAN, OFF) and any additional actions you add support for (like DEFROSTING/PREHEATING), so regressions in the mapping are caught.
