The firmware version of my device is 6542… The PIR human detection reports occupied and unoccupied status normally. By the way, when the millimeter-wave radar detects human presence, the device will not report either PIR motion or PIR no-motion signals throughout the radar occupancy period. Please refer to the attached logs.
To further diagnose the issue you reported, kindly provide a screenshot of your device logs. If convenient, you may send your account details and region (Europe, Americas, etc.) via private message, and I will apply for backend access permission.
Regarding the slow trigger response you mentioned, here is the functional difference between millimeter-wave radar and PIR infrared sensors for your installation reference: Millimeter-wave radar detects human targets by emitting millimeter waves and is more sensitive to radial movement. The PIR pyroelectric sensor works via infrared heat induction and excels at detecting tangential movement. Additionally, please avoid installing PIR devices near air vents to prevent interference with detection performance.
Hope the above information is helpful to you.
