Deconz Conbee2 - Hue motion Sensor not turning "off"

Sorry, more DeConz questions.
HA: 0.103.5
DeConz: 5.0 (Hassio add on)

im using a hue motion sensor, however ive put it into a fully black box, so it cannot detect any motion, yet the motion is staying as “on” and wont go “off”

i know its reporting, as i can see when i put it into the box, as the lux goes down to 1
