Tuya Smart Siren - WiFi or Zigbee Options

Add an audible response to a compatible smart-home automation. This compact Tuya siren works with separately connected sensors and lets you choose its alert sound in the app.

✅ Hear a configured sensor event - A compatible automation can trigger the siren when its conditions are met.

✅ Choose a sound that suits the alert - The app offers 32 selectable tones.

✅ Set the volume and duration - Adjust the alarm output to the intended room and scenario.

✅ Keep settings after a power interruption - Power-off memory retains the configured parameters.

Choose the Network Version for Your Home

The Zigbee version requires a compatible Tuya Zigbee hub or multimode gateway. The WiFi version connects to a 2.4 GHz network. Select the version that matches your setup.

The siren has no built-in door, motion or environmental sensors. Those functions require separate compatible sensors and automation settings. It needs continuous 5 V USB-C power and has no backup battery; the power adapter is separate.
