Binary sensor's state disregards for timer

1

hi,

idea: turn off lights X minutes after the aqara’s motion sensor (via zigbee2mqtt) stops detecting any motion.

this trigger:

platform: state
entity_id: binary_sensor.sensor_motion_wardrobe_occupancy
to: 'off'
for: 'minutes: 2'

never fires the automation.

however, the simple:

platform: state
entity_id: binary_sensor.sensor_motion_wardrobe_occupancy
to: 'off'

launches the action as expected as the motion is no longer detected.

any clue what is wrong?

regards,
Pavel
