Collect and execute similar operations together rather than performing them individually to reduce overhead and improve performance. This applies to entity creation, API calls, and state updates.

Key optimization strategies:

1. Batch entity additions: Collect all entities during initialization and add them with a single async_add_entities() call instead of multiple calls
2. Combine executor jobs: Group related synchronous operations into a single executor job to minimize expensive context switching between the event loop and thread pool
3. Use selective updates: Choose appropriate update mechanisms - use async_update_listeners() when state is already updated locally, or async_request_refresh() for buffered updates instead of immediate full refreshes

Example of batching entity creation:

# Instead of multiple calls:
if param_sensors:
    async_add_entities(param_sensors)
if status_sensors:
    async_add_entities(status_sensors)
if alarm_sensors:
    async_add_entities(alarm_sensors)

# Collect all entities and add at once:
all_entities = []
all_entities.extend(param_sensors)
all_entities.extend(status_sensors) 
all_entities.extend(alarm_sensors)
if all_entities:
    async_add_entities(all_entities)

This approach reduces function call overhead, improves code clarity, and can significantly improve performance when dealing with large numbers of operations.
