Hi
Is there a siren with Zigbee which is compatible with the ConBee III? I just found one from Bosch, but unfortunately it’s not on the compatibility list 
Are there some recommendations for outdoor sirens ?

Editing: I found the sirens from Heiman, but only for indoor use. Is anyone using this device? Is it possible to set the duration from the alarm sound in seconds without the bridge (only with Conbee & Homebridge)?
Best Ragards,
