Aqara M3 Hub - Not toggling devices Not adding any devicesmore

Hello everyone,

I’m experiencing a serious issue with my Aqara M3 Hub and would appreciate any help or insights.

Setup:
• Aqara M3 Hub
• Multiple Zigbee devices connected (dimmer switches, wall switches, outlets, relay)
• Integrated with Apple HomeKit
• Firmware is up to date
• Network tested via Wi-Fi and Ethernet (LAN)

Problem description:
Initially, everything works perfectly. All devices connect correctly, and automations in HomeKit run as expected.

However, after restarting the M3 hub (e.g. due to a power outage), the following happens:
• All Zigbee devices are still visible in the Aqara app and HomeKit
• Device status updates correctly (e.g. pressing a wall switch is detected, single/double taps are recognized)
• Signal strength appears normal
• The device cards in the Aqara app show the “on/off” state changing

But:
• Zigbee devices do not react when controlled from the Aqara app or HomeKit
• Lights do not turn on/off via the hub
• The hub is unable to control any Zigbee devices
• Adding new Zigbee devices is not possible

Physically controlling the switches still works, and the hub clearly receives events, but it seems unable to send Zigbee commands.

Temporary workaround:
The only way I’ve found to fix this is:
• Factory reset the M3 hub
• Re-add all devices manually

After that, everything works again — until the next power outage or restart, when the issue reappears.

Question:
• Is this a known firmware or Zigbee stack issue on the M3 hub?
• Is there a way to recover Zigbee functionality without factory resetting the hub?
• Any logs, settings, or troubleshooting steps I should check?

Thanks in advance for any help or feedback.

Hello, welcome to the forum. After the power goes out, the hub still gives information for some time that everything is OK (Zigbee devices send data once an hour). Therefore, an automation failure is possible. Make an uninterrupted power supply (mini ups 5 volts) for the gateway. It is also recommended to contact the support service to analyze the situation.
