I recently embarked on a project to integrate multiple Zigbee devices into my smart home ecosystem, and I wanted to share my experience with the community. My goal was to connect two Zendure HUB 2000 systems, each equipped with two AB2000 batteries, using Home Assistant (HA) and MQTT. At first, everything seemed to be working smoothly—data from the first HUB and its batteries were seamlessly integrated. However, when I attempted to add the second HUB, I encountered an unexpected issue: while the HUB data was accessible, the second set of batteries remained unconnected. This puzzled me, as both setups were identical.After some research and troubleshooting, I discovered that the issue might be related to how the devices were configured within HA. I reached out to the community for advice, and thankfully, I received some invaluable insights. One key takeaway was ensuring that each HUB and its associated batteries were properly identified and configured in the system. This involved checking the MQTT topics and ensuring that each device had a unique identifier.Through trial and error, I realized that the problem was not with the hardware itself but with the way the devices were registered in HA. By carefully reviewing the MQTT logs and adjusting the configuration files, I was able to resolve the issue. The second HUB and its batteries are now fully integrated, and everything works as intended.This experience taught me the importance of meticulous configuration and the value of community support. I’m now confident in expanding my smart home setup further, knowing that I can rely on both the tools and the community for guidance. If anyone else is facing similar challenges, I highly recommend checking your MQTT configurations and reaching out to the forums for help. Happy tinkering!
