Template returns always false

Configuration

While

{{states.sensor.last_room_motion.state}}

returns

motion_bedroom_all

{{ is_state('states.sensor.last_room_motion.state', 'motion_bedroom_all')}}

returns

false

I expect true

What am I doing wrong?

{{ is_state('sensor.last_room_motion', 'motion_bedroom_all') }}
