1) LinknLink APP cannot connect to the device's Bluetooth
Confirm that the device is in pairing mode and the LED indicator light flashes intermittently. If the LED indicator light flashes slowly, you need to press and hold the reset button until the indicator light flashes intermittently to reset the device. Please watch the video of LED indicator flashes intermittently,
If the device is in the network configuration state, but still cannot connect to the device Bluetooth, you need to kill the LinknLink APP, then open it and enter the device configuration page
2) Setup stalls on "Verifying device info on cloud "
Check the LED indicator status of the device. If it is still flashing intermittently, it means that the App has not successfully passed the Wi-Fi configuration information. Log out of the LinknLink APP, and longin the APP, try to setup device again.
If the device LED indicator is off, it means that the device is connected to Wi-Fi, but cannot connect to LinknLink Cloud through the Internet for device verification. You need to check the network settings of the router to see if there is a whitelist or other configuration to ensure that the device can access the Internet normally.
When upgrading the firmware, I always encounter the situation that the upgrade fails. You can use local upgrade instead. For specific methods, please refer to:
After the device firmware is upgraded, you need to clear the cache of LinknLink App to obtain the latest control program. Go to LinknLink App - Settings - Clear App Cache
I have configured the eMotion device correctly, and the LinknLink App shows that the device is running normally.
I have set up zones and named them
I have completed these two steps, but I still can't see the device in Alexa or Google Home. Because you skipped naming sub-devices in the initial configuration wizard, you cannot see the device in Alexa. Please follow the steps below to help name the sub-devices. 1)Go to LinknLink App and select "Presence" 2) Click top right " ... ", select "Settings" 3) Click Name Sub-Functions, named "Any Presence" and "Zones" 4) You should be able to see the motion devices in Alexa
The eMotion Pro uses a 24GHz radar sensor designed to prioritize forward detection. However, due to its wide radar coverage pattern, it may occasionally detect presence within a very close range (typically <1 meter) at its sides or back. Additionally, if mounted on wooden or plastic walls, the radar signal can penetrate these materials, potentially sensing movement behind the wall in proximity.
To minimize unintended detections:
Adjust Zone Placement: Set detection zones farther away from the sensor in the app. Avoid using zones close to the sensor’s sides/back for critical automations.
Optimize Sensitivity: In environments prone to false triggers (e.g., near thin walls or tight spaces), reduce the sensor’s sensitivity to Low via the app settings.
Review Automation Rules: Ensure automations (e.g., lights, alerts) are tied only to activity within your defined zones, not the sensor’s default detection range. These adjustments help balance reliable detection while reducing false triggers from peripheral areas. For further assistance, contact our support team.
If the OTA firmware upgrade fails, please follow the steps below to resolve the issue:
The latest Android and iOS apps are still under review in the app stores. We recommend manually installing the most recent Android version using the link below:
Open the app and connect to your eMotion Max device.
Tap “Upgrade Firmware” and wait for the process to complete.
If the upgrade fails, please take a screenshot or note the error message and send it to our support team at support@linknlink.com.
Most failures are due to router limitations that block the app from sending the upgrade instruction to the device (e.g., LAN isolation, broadcast filtering, or firewall settings).
If the update continues to fail through your home Wi-Fi:
Enable the mobile hotspot on your phone and create a simple 2.4GHz Wi-Fi network.
Reset the eMotion Max and re-pair it to this hotspot using the LinknLink App.
Once connected, try the firmware upgrade again—it should complete successfully under most conditions.
