Which smoke detector?

Hi all, not sure if this topic is still active, but a question regarding the intelligent smoke alarm you’ve mentioned: I can’t get the smart warning to work.
I’ve used it in flows with door sensors, pressing start in the homey app etc but haven’t heard an alarm.
Except ofc when you press the test button on the physical device.
Temperature readings work fine, all devices writing range of the bridge.
Thanks in advance
