As a long-time user of OpenHAB, I’ve recently encountered an intriguing challenge with my setup. After installing the Matter addon and attempting to integrate a Tasmota device, I noticed a significant increase in mDNS traffic, which led to network instability and high CPU usage. This was puzzling, as everything had been working smoothly prior to this change.
Upon investigation, I discovered that OpenHAB was flooding my network with mDNS queries, specifically targeting a device named C049EF8DABD0.local. This was unexpected, as I had no prior knowledge of this device. To mitigate the issue, I temporarily disabled several mDNS-related bundles, which restored network stability but left me without some core functionalities.
I decided to dig deeper into the matter. Through research and experimentation, I found that the issue was likely tied to the Matter addon and its interaction with the mDNS discovery process. After some trial and error, I managed to resolve the problem by completely removing the Matter addon and ensuring it was no longer lingering in my system. This not only restored my network performance but also reaffirmed the importance of thoroughly testing new integrations.
This experience taught me the value of understanding how different components interact within an ecosystem like OpenHAB. It also highlighted the importance of careful addon management and the benefits of community support in troubleshooting complex issues. If anyone else has encountered similar problems or has insights to share, I’d love to hear about your experiences!
