The smoke listener should have a settings option and/or default to behave like all the other Ring devices and be disarmed when Ring mode is Disarmed.
Currently the smoke listener stays active and can trigger alarms even when Ring is in Disarmed mode. While that sounds super safe, it is really too easy to trigger false alarms when users are home and have the fire department dispatched. I just had a false alarm yesterday and because I could not get to my phone fast enough the fire dept got sent and they were not too happy about it.
I do not see the difference between allowing a front door sensor to be disarmed when Ring is in Disarmed mode even though an intruder might kick it in, but the smoke listener will always be active even when I am home to hear the alarm and call the fire department myself.
At a minimum at least make a smoke listener option to arm/disarm with Ring arm/disarm.
