Quick verdict
The Aeotec Siren 6 is the go-to Z-Wave siren for Home Assistant alarm setups. Multiple tones and volume levels make it versatile, a built-in rechargeable battery keeps it sounding if power is cut, and Z-Wave JS integration is rock solid. It's a component, not a product — pair it with sensors and automations for a proper DIY alarm.
Standout: Configurable multi-tone Z-Wave siren with adjustable volume and built-in battery backup — an ideal building block for a DIY alarm system.
