Zooz Siren & Bell with 50 Sounds & MP3/WAV | ZSE50 | Z-Wave Plus 800 EU Series

🚨 The Smartest Siren in Your Smart Home

A smart home deserves a smart siren. The Zooz ZSE50 Z-Wave 800 Series Siren & Chime is more than just a security speaker—it's a fully configurable sound device for your home automation system. Use it as a burglar alarm, doorbell, water leak alert, welcome chime, or even a dryer-ready announcement. With space for 50 sound files (MP3 or WAV) and 16 MB of internal memory, you can choose exactly which sound suits which automation.

The ZSE50 works directly with Home Assistant via Z-Wave JS and is also compatible with Homey – completely local, without the cloud. Thanks to its built-in backup battery (400 mAh), the siren remains operational for up to 12 hours during a power outage.
