Yellow indicator flashes slowly
Aqara hub Yellow indicator flashes slowly: firmware update
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
A slow-flashing yellow indicator on an Aqara Hub E1 or Camera Hub G3 means the hub is upgrading its firmware. Keep power and Wi-Fi connected until the LED returns to steady blue; on Camera Hub G3, AI detection features pause until the upgrade finishes.
Safety first
Stop and check this first
- Do not unplug the hub or press its button to reset or factory-reset the device while the yellow indicator is flashing slowly for a firmware upgrade.
- On Camera Hub G3, face, personoid, gesture and pet detection are intentionally paused while firmware is upgrading; wait for the upgrade to finish rather than resetting the camera.
Safe checks you can perform
- Distinguish slow yellow flashing from fast network-setup flashing
- Keep the phone on the hub's Wi-Fi and wait for steady blue
- Check firmware versions on the hub and paired Zigbee lighting
Leave these tasks to a qualified professional
- Do not attempt this professional task: Verify local Wi-Fi and power conditions for hub firmware updates
- Do not attempt this professional task: Update paired Zigbee lighting routers required for Ark 2.0 recovery
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Verify local Wi-Fi and power conditions for hub firmware updates
What they doThe technician confirms that the mobile phone is connected to the exact Wi-Fi network where the hub resides, verifies stable 5V USB power, and monitors the update from the hub details page until the indicator returns to steady blue.
They must show youthe firmware update screen in Aqara Home, the LED returning to steady blue, and AI functions resuming on Camera Hub G3.
In writinghub model, installed firmware version and confirmed steady blue indicator state after completion.
Update paired Zigbee lighting routers required for Ark 2.0 recovery
What they doThe professional checks and updates firmware across the hub and compatible Zigbee devices (such as LED Strip T1, LED strip driver T1, Ceiling Light T1 and Spotlight V1) so they meet the minimum versions listed in Aqara's Ark 2.0 documentation.
They must show youthe updated firmware versions on the hub and on any paired Aqara Zigbee lighting routers.
In writingdevices updated, minimum firmware versions verified and post-update communication status.

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Distinguish slow yellow flashing from fast network-setup flashing
- Who:
- you, observing the status indicator on your Aqara Hub E1 or Camera Hub G3.
- How:
- check whether the yellow indicator is flashing slowly rather than flashing quickly, and check the hub's details page in the Aqara Home app to see whether a firmware update is in progress.
- Result that matters:
- confirm that the hub is upgrading firmware rather than waiting for initial Wi-Fi onboarding.
- If the yellow light flashes slowly while an update runs:
- leave power and Wi-Fi connected without pressing the button.
- If the yellow indicator flashes quickly:
- the hub is waiting to connect to a network rather than upgrading firmware.
- Evidence to keep:
- observed yellow flash rate and the firmware update status shown on the hub's page in Aqara Home.

Keep the phone on the hub's Wi-Fi and wait for steady blue
- Who:
- you, with your mobile phone connected to the same Wi-Fi network as the Aqara hub.
- How:
- keep USB power and router Wi-Fi stable until the upgrade finishes and the indicator returns to steady blue (working properly); on Camera Hub G3, wait until completion before testing face, personoid, gesture or pet detection.
- Result that matters:
- allow the firmware installation to finish and restore normal hub and AI operation.
- If the LED turns steady blue and Camera Hub G3 AI features resume:
- retain the updated firmware version.
- If the update cannot be started or completed from the app:
- verify that your phone is on the same Wi-Fi network as the hub.
- Evidence to keep:
- return of the indicator to steady blue and normal response of hub and G3 AI features afterward.

Check firmware versions on the hub and paired Zigbee lighting
- Who:
- you, reviewing the device details page inside the Aqara Home app.
- How:
- connect your phone to the Wi-Fi network where the hub is located, select the hub on the device page, open its details page and tap firmware update; also check firmware on paired Zigbee devices such as LED Strip T1, LED strip driver T1, Ceiling Light T1 or Spotlight V1.
- Result that matters:
- ensure the hub and its Zigbee lighting routers meet Aqara's firmware requirements for stable communication.
- If the hub and paired Zigbee devices show current firmware and remain online:
- keep the recorded versions.
- If the hub goes offline or fails to update:
- request a technician check of the local Wi-Fi link or contact Aqara support.
- Evidence to keep:
- recorded firmware versions for the hub and its paired Zigbee lighting accessories.

What it means
In the official user manuals for Aqara Hub E1 (HE1-G01) and Camera Hub G3 (CH-H03), 'The yellow indicator flashes slowly' means the device is upgrading its firmware, whereas a fast-flashing yellow indicator means it is waiting to connect to the network. In addition, the Camera Hub G3 FAQ explains that AI functions (face, personoid, gesture and pet detection) are temporarily interrupted during a firmware upgrade to ensure upgrade speed and experience. Other Aqara hub models may differ, and a slow yellow flash alone never proves that a component is faulty.

- Intentional pause of AI detection on Camera Hub G3 during upgradePossible
On Camera Hub G3, Aqara interrupts face, personoid, gesture and pet detection while firmware is upgrading so hardware resources are dedicated to completing the update.
Evidence: Aqara Support Center: Camera Hub G3 FAQ (EN)
- System firmware alignment for Zigbee stability and Ark 2.0 recoveryPossible
Aqara's hub FAQs require updating the firmware of the hub and connected Zigbee lighting routers to the latest version to maintain stable communication and local disaster recovery.
