Yes, and that’s exactly the issue: the `alarm_motion` capability is only supported for `sensor` devices, not for `homealarm` devices. It doesn’t really make sense to use the latter device class, because that’s meant for home alarm _controller_ devices, not for sensors that might be used to trigger an alarm but have lots of other applications too.
