I’ve been experimenting with setting up multiple Zigbee2MQTT instances across my home, and I must say, the results have been fantastic! 
By running three separate instances, each managing a different zone of my house, I’ve been able to significantly improve the stability and responsiveness of my smart devices. Let me share my setup and some tips for anyone considering a similar approach.
First, I’ll walk you through my configuration. I have three Raspberry Pi devices, each running a Zigbee2MQTT instance connected to a different part of my home. One handles the basement, another the first floor, and the third the second floor. By distributing the devices this way, I’ve noticed a marked improvement in signal strength and reliability, especially in areas that were previously problematic due to thick walls or interference.
One of the challenges I encountered was ensuring smooth communication between the instances. I solved this by carefully planning the Zigbee channels for each instance to avoid overlap. I also made sure to use high-quality USB adapters and positioned them strategically to maximize coverage. Another key factor was optimizing the MQTT broker settings to handle the increased load efficiently.
Here are a few tips for anyone looking to implement a similar setup:
- Channel Management: Assign different Zigbee channels to each instance to minimize interference.
- Adapter Placement: Position your Zigbee adapters in central locations within each zone to ensure optimal coverage.
- Regular Firmware Updates: Keep your Zigbee devices and firmware up to date to benefit from the latest improvements and bug fixes.
- Testing and Monitoring: Regularly test the connectivity of your devices and monitor the logs for any issues that might arise.
By organizing my smart home into zones, I’ve not only improved the performance of my devices but also made it easier to troubleshoot and manage them. It’s been a rewarding project, and I’m excited to see how this setup evolves as I add more devices in the future!
