I have a few remarks following an AI analysis:

• Normalize automation["entity_type"] for comparisons — e.g. lower-case once and use that for both the "asset" branch (wanted == "asset") and the name check (entity_type["name"].lower() != wanted), so values like "Sequence" vs "sequence" don’t skip or mis-apply automations.
• Drop unused imports in tests — remove Entity from tests/services/test_status_automation_service.py if it isn’t referenced.

Snippet for the normalization:

    entity = entities_service.get_entity(task["entity_id"])
    entity_type = entities_service.get_entity_type(entity["entity_type_id"])
    wanted = (automation.get("entity_type") or "").lower()
    if wanted == "asset":
        if not assets_service.is_asset_type(entity_type):
            return
    elif entity_type["name"].lower() != wanted:
        return
