Key Technical Breakthroughs

1. Ground Truth Verification System

Problem: UniFi API returns stale cached responses, causing false positive verification.

Solution: Multi-read consistency checking with cache-busting techniques.

# Multi-read verification detects API lies
for read_num in range(5):
    time.sleep(2)  # Progressive delay
    # Add cache-busting headers
    headers = {
        "Cache-Control": "no-cache, no-store, must-revalidate",
        "X-Cache-Bust": str(int(time.time() * 1000))
    }
    response = api.get_device(device_id, headers=headers)
    # Analyze consistency across reads

2. Device-Aware Intelligence

Problem: Different UniFi models have varying port naming support and firmware limitations.

Solution: Comprehensive device capability database with smart update strategies.

# Device capability detection
capability = detector.detect_capabilities(device_model, firmware_version)

if capability.port_naming_support == PortNamingSupport.RESETS_AUTOMATICALLY:
    # US-8-60W firmware 7.2.123 automatically resets port profiles
    strategy = "AVOID"  # Skip updates, warn user
elif capability.port_naming_support == PortNamingSupport.LIMITED:
    # USW Flex 2.5G 5 has network override restrictions
    strategy = "CAUTIOUS_API"  # Use minimal payload, enhanced verification

3. API Cache Dependency Fix

Problem: Tool skipped necessary updates because API reported stale "already correct" names.

Solution: Removed API read dependency from update decisions.

# BEFORE (Broken):
if is_default_name and not is_uplink:  # Trusted stale API data

# AFTER (Fixed):
if lldp_device_name and lldp_name_is_valid and not is_uplink:
    # Always attempt LLDP-based updates regardless of API claims

Device Compatibility Matrix

Device Model	Firmware	Support Level	Notes
USW Flex 2.5G 8 PoE (USWED37)	2.2.7+	✅ FULL	Reliable API port naming
USW-Ultra-210W (USM8P210)	2.2.7+	✅ FULL	Enterprise-grade reliability
Dream Machine Pro Max	5.0.10+	✅ FULL	Gateway with full support
USW Flex Mini (USMINI)	2.1.6+	✅ FULL	Compact switch, full features
USW Flex 2.5G 5 (USWED35)	2.2.7+	⚠️ LIMITED	Network override restrictions
US 8 60W (US8P60)	7.2.123	⚠️ LIMITED	Port profile auto-reset (fixed in UniFi 10.0.162)
USW Lite 8 PoE (USL8LP)	7.2.123	⚠️ LIMITED	VLAN selection issues (improved in 10.0.162)

Critical: UniFi Network Application 10.0.162 early release resolves most device-level rejection issues.

Troubleshooting

Common Issues

Port names not persisting:

1. Check device compatibility: python -m unifi_mapper.analyze_network_capabilities
2. Use verification: unifi-mapper --verify-updates
3. Check firmware: Upgrade to UniFi Network Application 10.0.162+

API authentication failures:

1. Verify controller URL and port (443 for UniFi OS, 8443 for legacy)
2. Check API token validity
3. Ensure local controller account (not UniFi Cloud account)

Verification failures:

1. Use ground truth verification: python -m unifi_mapper.verify_cli --consistency-check
2. Check for device auto-reset behavior
3. Consider manual UI configuration for problematic devices
