I need some device to output sound, be it as a notification that the alarm is armed when you open the door, or as siren inside when someone breaks a door or window at night, or in case the zigbee CO or SMOKE sensor in the basement goes off and you are asleep 2 stories above it.
I stumble across those WIFI sirens that seem to be able to play different sounds, are USB powered and have a battery backup.
They ship for ~$20. https://www.aliexpress.com/item/33016927095.html?spm=a2g0s.9042311.0.0.2e3d4c4dp1UQqT
Has anyone any experience with them, used them, and knows how they could be integrated in HA?
