# Code Refactoring Summary

## Issue Description

The code between lines 484-498 in `TasmotaManager.py` was duplicating pattern matching logic that was already implemented in the `is_hostname_unknown` function. This duplication made the code harder to maintain and increased the risk of inconsistencies if one implementation was updated but not the other.

## Changes Made

### 1. Replaced Duplicated Pattern Matching Logic

The original code:

```python
# Check if device name or hostname matches unknown patterns
unifi_name_matches_unknown = False
for pattern in unknown_patterns:
    pattern_lower = pattern.lower()
    pattern_regex = pattern_lower.replace('.', r'\.').replace('*', '.*')
    # Check if pattern already starts with ^
    if pattern_regex.startswith('^'):
        regex_pattern = pattern_regex
    else:
        regex_pattern = f"^{pattern_regex}"
    if (re.match(regex_pattern, device_name.lower()) or 
        re.match(regex_pattern, device_hostname.lower())):
        unifi_name_matches_unknown = True
        self.logger.debug(f"Device {device_name} matches unknown device pattern: {pattern}")
        break
```

Was replaced with:

```python
# Check if device name or hostname matches unknown patterns
unifi_name_matches_unknown = (
    self.is_hostname_unknown(device_name, unknown_patterns) or 
    self.is_hostname_unknown(device_hostname, unknown_patterns)
)
if unifi_name_matches_unknown:
    self.logger.debug(f"Device {device_name} matches unknown device pattern")
```

### 2. Benefits of the Change

1. **Code Reuse**: The change leverages the existing `is_hostname_unknown` function, which already handles pattern matching logic correctly.
2. **Maintainability**: By centralizing the pattern matching logic in one place, future changes only need to be made in one location.
3. **Consistency**: Ensures that pattern matching is performed consistently throughout the codebase.
4. **Readability**: The code is now more concise and easier to understand.

### 3. Testing

A comprehensive test script `test_get_tasmota_devices.py` was created to verify that the changes work correctly. The script includes tests for:

1. Devices that match unknown patterns
2. Devices affected by the Unifi hostname bug
3. Devices that match exclude patterns

All tests passed, confirming that the changes maintain the same behavior and functionality as the original code.

## Conclusion

This refactoring improves the codebase by reducing duplication and increasing maintainability without changing the behavior of the application. The pattern matching logic is now centralized in the `is_hostname_unknown` function, making it easier to maintain and update in the future.
