Pull request overview

This PR updates the bemfa Home Assistant integration to replace deprecated constants and functions scheduled for removal in HA Core 2025.5, 2025.10, and 2026.1. The changes include migrating from deprecated string constants to enum-based constants, updating light color temperature attributes from mireds to kelvin, replacing the deprecated StrEnum import, and updating the paho-mqtt client initialization.

Key changes:

• Replaced deprecated state constants (STATE_CLEANING, STATE_LOCKED, STATE_IDLE) with new enum types (VacuumActivity, LockState, CameraState)
• Converted light color temperature from mireds-based attributes to kelvin-based attributes
• Updated MQTT client initialization with new paho-mqtt API (callback_api_version parameter)

The comparison with VacuumActivity.CLEANING will fail because state is a string but VacuumActivity.CLEANING is an enum. The enum needs to be converted to its string value for comparison.

Change to:

if state in [STATE_ON, VacuumActivity.CLEANING.value]

or use:

if state in [STATE_ON, str(VacuumActivity.CLEANING)]

Suggested change

	if state in [STATE_ON, VacuumActivity.CLEANING]
	if state in [STATE_ON, VacuumActivity.CLEANING.value]

The comparison with CameraState.IDLE will fail because state is a string but CameraState.IDLE is an enum. The enum needs to be converted to its string value for comparison.

Change to:

return lambda state, attributes: MSG_OFF if state == CameraState.IDLE.value else MSG_ON

or use:

return lambda state, attributes: MSG_OFF if state == str(CameraState.IDLE) else MSG_ON

Suggested change

	return lambda state, attributes: MSG_OFF if state == CameraState.IDLE else MSG_ON
	return lambda state, attributes: MSG_OFF if state == CameraState.IDLE.value else MSG_ON

The comparison with LockState.LOCKED will fail because state is a string but LockState.LOCKED is an enum. The enum needs to be converted to its string value for comparison.

Change to:

return lambda state, attributes: MSG_OFF if state == LockState.LOCKED.value else MSG_ON

or use:

return lambda state, attributes: MSG_OFF if state == str(LockState.LOCKED) else MSG_ON

Suggested change

	return lambda state, attributes: MSG_OFF if state == LockState.LOCKED else MSG_ON
	return lambda state, attributes: MSG_OFF if state == LockState.LOCKED.value else MSG_ON
