As someone managing a large property with a complex smart home ecosystem, I’ve invested significant time and effort into refining a robust and resilient setup. With over 200 devices deployed and a variety of hubs in use, my experience may help others designing or scaling their own systems. Below are my key observations, the progression of my setup, and recommendations based on extensive testing.
Current Hub Deployment
I currently have the following hubs strategically distributed throughout the property:
3 x Aqara M3 Hubs
4 x Aqara G5 Camera Hubs
4 x Aqara M2 Hubs
3 x Aqara M100 Hubs (under testing)
1 x Aqara G410 Doorbell Hub
Evolution of My Setup
Initial Phase: Floor-Based M2 Hub Setup
I began with three M2 hubs, allocating one per floor. While this approach worked reasonably well, I occasionally encountered issues such as:
- Devices going offline without warning
- The need to manually restart hubs or power-cycle devices to restore connectivity
Despite otherwise solid performance, these periodic glitches indicated some systemic instability.
Upgrade to M3 Hubs: Improved Signal, Same Glitches
When the M3 hubs were released, I replaced the M2s with M3s, expecting:
- Enhanced signal strength
- Improved reliability
- Better automation performance
While signal strength did improve significantly, the rare connectivity glitches persisted. This suggested that signal alone wasn’t the root issue—it pointed more toward architecture or mesh stability limitations.
On the plus side, the M3s introduced local automation control, which proved to be a substantial improvement:
- Most automations now run entirely on the hubs without requiring internet
- Confirmed by physically disconnecting internet and successfully triggering automations
- The hub clustering feature, though still not fully transparent, seems to designate a master hub for local app control
Final Optimization: Room-Based Hub Deployment
Rather than segmenting the home by floors, I decided to allocate a dedicated hub to each primary room. This meant:
- Reprovisioning the M2 hubs for use in individual rooms (Kitchen, Living Room, Office, Bedrooms, etc.)
- More granular control and fault isolation
- Greater reliability and reduced complexity per hub
Result:
This has been the most effective and stable configuration. System uptime has been near-perfect for months. If a hub does fail, it typically impacts just one room instead of several, making troubleshooting and recovery far easier.
Outdoor Coverage with G5 POE Cameras
For perimeter and outdoor smart devices (motion sensors, relays, etc.), I’ve integrated them with the G5 POE Camera Hubs, which offer:
- Excellent Zigbee signal strength, even across distances and through outdoor walls
- Local automation handling directly on the G5 units
- Seamless integration into the larger Aqara system
This has enabled reliable motion lighting and perimeter security triggers independent of the core indoor system.
Device Count and Stability
With over 200 smart devices (sensors, switches, relays, locks, cameras, and more), my home automation system pushes the limits of typical residential setups.
Despite the complexity, the system has proven rock solid thanks to:
- Room-based hub isolation
- Local automation processing
- Reliable camera hub performance outdoors
- Thoughtful pairing of devices to the nearest appropriate hub
Final Thoughts & Advice
- Clustered local control via M3/M2 hubs works well, though transparency on “master” logic would be helpful
- Signal strength alone isn’t enough—device distribution strategy is key
- Resilience improves dramatically when you decentralize your hubs
- Outdoor automation benefits from camera hubs with built-in Zigbee radios
- Internet independence is now a reality for most automations
- Scalability requires clear mapping and documentation of device-hub assignments
While individual mileage may vary, my journey through numerous home automation configurations has led to a solution that balances performance, reliability, and fault tolerance.
If you’re scaling up your own setup—especially in large or complex properties—my strongest advice is to decentralize and think in rooms, not floors. Your future self (and your family) will thank you.
