I still don’t understand the difference between the Hub M100 and the M2 and M3. I purchased the M100 thinking it was enough. Did I make a mistake?

@josuesanchez If you only need to connect a small number of Aqara Zigbee devices (e.g., 20 or fewer) or Matter devices, the M100 would suffice.
If you don’t need Matter support but want to connect more Aqara Zigbee devices (e.g., up to 50), the M2 is recommended. The M2 also supports infrared code device control, voice announcements, and customized voice alerts.The M3 includes all features of the M100 and M2, plus additional capabilities:

  • Robust central hub capabilities, allowing it to manage other “regular” hubs like the M2 or M100.
  • Local execution of complex hub automations without relying on cloud services.
  • Storage of device logs for troubleshooting or monitoring.
  • Local network control of devices via the Aqara Home App, even when offline.

@josuesanchez Let’s break down the differences between the Hub M100, M2, and M3 based on the available information:

Hub M3 vs M2:

The Aqara M3 is a Matter controller that supports Thread version devices, but specific details about the M2 are not fully provided in the reference materials .

Hub M100 vs M3/M2:

  • The M100 supports Matter Controller and Thread Border Router (BR), and enables automatic device discovery and network access via Bluetooth . It also acts as a Matter Bridge, connecting Zigbee devices to third-party ecosystems, and functions as a Thread Border Router and mesh extender .
  • The M100 does not support WiFi relay function, while details on M2/M3’s WiFi relay are not specified .
  • Unlike some other hubs, the M100 does not require scanning a QR code for binding (since it’s not a security device with eMMC storage) .

Whether the M100 is “enough” depends on your needs. If you require Matter/Thread support, Bluetooth device discovery, or local automations (which the M100 offers ), it may suit your setup. If you need features specific to M2/M3 (like unmentioned capabilities), you might want to assess further.

No need to worry too much—many users find the M100 versatile for basic to mid-range smart home setups. If you have specific use cases in mind, feel free to share, and the community can help confirm!
