New stop action and idle activity for lawn mowers

· One min read
Paul Bottein

As of Home Assistant Core 2026.10, LawnMowerEntity supports a stop action and an IDLE activity.

stop cancels the current mowing task without returning the mower to the dock. It differs from pause, which keeps the task so it can be resumed, and from dock, which sends the mower home. To support it, add LawnMowerEntityFeature.STOP to the supported features and implement stop or async_stop.

LawnMowerActivity.IDLE describes a mower that is stopped, but neither docked nor paused. Integrations that mapped such a state to PAUSED or ERROR should now use IDLE.

More details can be found in the documentation.

Example​

class MyLawnMower(LawnMowerEntity):
    _attr_supported_features = (
        LawnMowerEntityFeature.START_MOWING
        | LawnMowerEntityFeature.DOCK
        | LawnMowerEntityFeature.STOP
    )

    async def async_stop(self) -> None:
        """Stop the mower and cancel the current task."""
        await self.mower.stop()
        self._attr_activity = LawnMowerActivity.IDLE
        self.async_write_ha_state()
