Network Performance and Duplicate Log Entries

I’ve been working on optimizing my home automation setup, and I’ve encountered an interesting issue with my network configuration. I’m hoping to get some insights or advice from the community to help me troubleshoot and resolve this.

The Setup

I have a mixed network environment with both Home Assistant (HA) and other IoT devices. My network includes:

  • A Ubiquiti EdgeRouter for routing and management.
  • A Dell OptiPlex Mini running HAOS with several add-ons like Sonarr, Radarr, and Scrypted.
  • A Synology NAS for storage and backups.
  • Multiple IoT devices, including smart lights, sensors, and cameras.

The Issue

Recently, I noticed that my network performance seemed to degrade, particularly when adding new devices or reconfiguring existing ones. I also started seeing duplicate log entries in my HA logs, which made it harder to diagnose issues. For example, a single motion sensor event would appear multiple times in the logs, making it difficult to track down the root cause of any problems.

What I’ve Tried

  1. Network Segmentation: I considered separating my network into a Home and IoT VLAN to isolate traffic. However, I’m not entirely sure how to implement this properly without disrupting existing services.
  2. Log Analysis: I reviewed the logs to identify patterns or recurring issues. The duplicate entries seemed to correlate with certain automation triggers, but I couldn’t pinpoint the exact cause.
  3. Firmware Updates: I updated the firmware on my router and NAS to ensure they were running the latest versions, but this didn’t resolve the issue.
  4. Traffic Monitoring: I used tools like nmap and Wireshark to monitor network traffic, but the results were overwhelming and didn’t provide clear insights.

Current Status

The issue persists, and while it’s not critical, it’s definitely a nuisance. I’m concerned that if left unresolved, it could lead to more significant problems down the line, especially as I continue to expand my IoT ecosystem.

Questions for the Community

  • Has anyone else experienced similar issues with duplicate log entries or network performance degradation?
  • What strategies have you used to effectively segment your network without causing disruptions?
  • Are there specific tools or techniques you recommend for diagnosing and resolving network-related issues in a mixed IoT environment?

I’d greatly appreciate any advice or recommendations you might have. Let’s work together to make my smart home smarter and more efficient!
