Hello,
the motion sensor (in 3 in 1 sensor) go in sleep mode after the sensor doesn’t get movement. It goes in sleep mode means that even if someone passes in front of sensor, no way to detect the movement. So what i have to do is to press the little blue bottom on sensor side to wake up the sensor. After that the red led will blink and the sensor is able to detect movement.
There is a way to leave the sensor in a kind of “stand by” mode but without sleep?
Thanks
