Aqara Hub M3 Offline or Zigbee Devices Not Responding

Problem Description

Your Aqara Hub M3 is showing offline in the Aqara Home app, HomeKit, or your Zigbee sensors and accessories are not responding.

Common Causes

• Hub not connected to WiFi or Ethernet
• Zigbee channel interference
• Devices out of range or mesh network weak
• Hub firmware needs updating
• HomeKit sync issues

Solutions

1. Check Hub Connection Status

• Blue breathing: Connected and working
• Blue solid: Connecting
• Yellow: Firmware updating
• Red: Error or offline

2. Power Cycle the Hub

1. Unplug the hub from power
2. If using Ethernet, disconnect the cable
3. Wait 30 seconds
4. Reconnect Ethernet (if used), then power
5. Wait 2-3 minutes for full startup

3. Re-pair Offline Zigbee Devices

1. Open Aqara Home app and find the offline device
2. Delete/remove the device from the app
3. Reset the device (usually hold button until LED flashes)
4. Add the device back through the hub

4. Change Zigbee Channel

WiFi and Zigbee can interfere on certain channels:

1. Open Aqara Home app then Hub settings
2. Find Zigbee channel setting
3. Try channels 15, 20, or 25 (least WiFi interference)

5. Improve Zigbee Mesh Network

• Add Aqara Smart Plugs or wired devices to act as repeaters
• Battery devices do not repeat - they rely on the mesh
• Keep hub away from metal objects and electronics

6. Reset HomeKit Connection

1. In Apple Home app, remove the Aqara hub
2. In Aqara app, go to Hub settings then HomeKit
3. Reset HomeKit pairing
4. Re-add to HomeKit by scanning the code

7. Factory Reset

1. Press and hold the hub button for 10+ seconds
2. LED will change color and hub will reset
3. All devices and settings will be lost
