The Heiman Zigbee Smart Siren is an easy win for low-cost local alarm builds. You get both a loud audible alert and a flashing strobe, so alarms are harder to miss in noisy homes. It is not premium hardware, but it is dependable with ZHA and Zigbee2MQTT and delivers excellent value for budget-first setups.
Standout: Zigbee siren with built-in flash strobe light for combined audio and visual alerting.

sound options are more limited than Z-Wave alternatives like the Aeotec Siren 6
Best for
Zigbee-based Home Assistant alarm setups wanting a siren with visual strobe
users who prefer Zigbee over Z-Wave for their sensor mesh

you want premium build quality and extensive configuration options
you are not running a Zigbee coordinator
Privacy and local-control notes
This is a Zigbee-only accessory with fully local control through your coordinator. It does not require a vendor cloud account, and automation events stay inside Home Assistant and your local mesh network.

Buying reality check
Price notes: Budget tier pricing makes it a strong add-on for DIY alarm systems. If you already run Zigbee, this is one of the cheapest ways to add both sound and visual alerting.
