AQARA RTCGQ11LM Motion Sensor Not Detecting Door Handle Movement

Hello, I have purchased an AQARA RTCGQ11LM motion sensor.
I intended to use it for a rather unusual application. I wanted to point it at the door handle to detect movement. Recently, a group of burglars has been prowling the estate and this is how, by pulling on the handles, they check whether the door is open.
I paired the detector with the AQARA m1s gateway. Unfortunately, it does not detect the movement of the objects themselves. I couldn't find information on this anywhere, everyone reckons that only humans/objects can move in the flat.
Unless I am doing something wrong. They also write in the auctions about being able to adjust the sensitivity. Rubbish - there is no such option in the dedicated AQARA Home app

I would use a limit switch for the handle sooner.
The above-mentioned motion detector is used in front of the door, but then every person in front of the door will cause an alarm.
I have tracked down with the limit switch: two tampering attempts.

This will definitely not work. The device purchased is actually a "presence sensor", that is, it detects an object using infrared emissions. That is, in short, the motion sensor only analyses the heat of a moving person, but "does not see" objects such as a door handle.

In this case, the best and most reliable solution is to use a contactor, a limit switch, a reed switch or a simple optoelectronic barrier with a violation signal. There are also cheap and off-the-shelf solutions, for example simple personal alarms equipped with a sensor with a contactor that can be used to secure doors or windows.

Well overall, a limit switch makes sense, but I also bought the sensor with some modern “Smart” solutions in mind so it would send me a notification when I'm out of the flat.
I already have an opening sensor and a camera. They work great.

This sensor is perfect for securing a hallway or balcony door. That is, when set up correctly, it will be able to detect a perpetrator who manages to force a door or window.

Thanks for your help. AQARA also has a vibration sensor in the range

I'm curious if if I stick it on the lock housing at the handle it will be able to sense vibration from pressure!?

P.S. As I write the post they have reported another break-in😱

Perhaps the vibration sensor will work properly and prove to be sensitive enough? You can easily check and then test it thoroughly, which will only take a few hours, a few days at most. However, if the sensor you bought (online) turns out to be ineffective, you can return it without any problem.

I have other thoughts, however. Where do they get stolen like this today? Are these incidents systematically reported to the police? In my region this is completely unlikely. However, since there is such a big problem with burglaries or attempted burglaries in your area, I guess I would opt to design and install a good surveillance and alarm system with monitoring. It is likely that the cost of implementing the system will be less than the damage from one successful burglary.
