2. **Control Issue:** Due to the lack of proper status retrieval, controlling the air conditioner using the entity is also impaired.
## Expected Behavior
The expected behavior of the lumi.acpartner.mcn04 entity is to display all relevant air conditioner statuses, including but not limited to cooling, heating, and off. This would enable proper control over the air conditioner, aligning with user expectations and the functionality observed in previous versions.
