The three Zooz 4-in-1 sensors are paired with no security.
They are all reporting motion now and then even when there is no motion.
I set the sensitivity to 7, the least sensitive. They are still detecting motion every few minutes. I have Wyze cameras pointing in the same direction as the sensors, and no motion is detected on those cameras.
As a test, I put one of the misbehaving Zooz sensors in a 10 x 12 closed room with no windows. With the HE app open on my iPad monitoring the Zooz sensor, and the Wyze app open on my wife’s iPad watching the camera in the same room, I did not see any motion nor did the camera detect any motion when the motion event was detected by the Zooz sensor. The Zooz sensor is sitting on top of the Wyze camera pointing in the same direction. I have placed the sensor next to the camera, on the other side of the room. There is no window nor is there a HVAC vent in that room.
Thinking it might be a temperature change, I set all of them to report at the highest (5F) change with no difference. Still reporting random motion.
Remembering I had an Aqara motion sensor in the drawer before I got the Tuya ZigBee repeaters, I paired it with HE, put it in the same closed room, and no motion was detected.
The real puzzler is these Zooz sensors did not report random motion when they were paired with the HE hub. They just ate batteries and hosed the Z-Wave mesh because they were the 500 series. Now they are paired with the Zooz Z-Stick.
WAF is falling. Have 3 more Aqara motion sensors coming today (in stock at my local Amazon warehouse).
As an ex-diagnostic tech in an automotive shop, the ‘why’ was an important part of the diagnosis. Just slapping a part on and not questioning why it failed could result in a comeback.
