Mi Motion Sensor FAQ

Question

Accepted Answer

Q1.How to identify if the Mi Motion Sensor works properly?

A:① Poke the reset hole of the Motion Sensor with the eject pin. If the Hub makes voice prompts, "Normal link confirmed", it indicates that the Hub and the Motion Sensor communicates properly. If there is no voice prompts, please move the sensor closer to the Hub and try again. If there is still no voice prompts, the sensor might be deleted or it might runs out of battery. Please refer to the device adding methods to add the device or replace the battery.

② Put hand in front of the lens, enter the home of Motion Sensor in Mi Home app, refresh the device records (log). If there is 1 to 5 minutes' log around this moment, it indicates that the device works properly.

Q2.Where should Mi Motion Sensor be installed and how to install them?

A:① Install in the area that needs to be monitored, for example in the living room or bedroom (during installation, please refer to the portion of the manual regarding the motion sensor's operating range).

②A coffee table, shoe cabinet or desk can be used, but ensure that it is installed close to the edge (recommended height is 1.2m to 2.1m).

③ Do not place on a metal surface or allow anything to block the motion sensor.

Q3.If a pet enters the detection area of Mi Motion Sensor, will it trigger the sensor?

A:Yes. If you do not want a pet to trigger the sensor. Please refer to the detection diagram in the quick start guide and place the motion sensor in a higher location. Thus a pet will not trigger the sensor when it moves on the ground. (Please refer to the quick start guide regarding the installation options).

Q4.The Mi Motion Sensor does not respond, and indicator light does not blink when I poke the reset hole. Why is that?

A:Possible reason:

① It runs out of battery

② PCB is damaged

③ Sensor crashes

Q5.The Mi Motion Sensor does not respond, and indicator light does not blink when I poke the reset hole. Why is that?

A:Possible reason:

①PIR sensor or related circuit is damaged.

② Sensor is triggered each minute and it is right in interval between each minute.

③ The detecting interval extends to 10 minutes in sub-health or warehouse mode.

④ Lens are damaged.

Q6.The Mi Motion Sensor does not respond, but indicator light is dim when I poke the reset hole. Why is that?

A:Battery low

Q7.The Mi Motion sensor is not sensitive to detect motion. Why is that?

A:Motion sensor detects once every minute by default and goes to sleep mode after it is triggered. After one minute, it is triggered again. It might be right in the sleep mode when using it.

Q8.Some trigger interval of the Motion Sensor is long and some is short. Why is that?

A:One hour after it is connected to the network (Newly added to the network mode), the Motion Sensor is triggered once every 5 seconds. If it is not triggered within an hour, it automatically enters Normal User Mode. It is then triggered once every minute.

Q9.There is no motion of human or pets in the detection area but why can I still see the log in the app?

A:It might happen if the Motion Sensor is placed close to the heat source, micro wave stove, air conditioner or the area that is exposed to strong light.

Q10.How can the motion sensor be reset? When should it be reset?

A:① Push in and hold the reset hole on the device for 3 seconds. The indicator will flash 3 times before resetting to factory settings.

②If a sensor needs to be paired with another sensor hub, it will need to be reset before the new pairing will succeed.
