Will it work with my smart speaker
Smart speakers are not Z-Wave controllers so you will need a compatible Z-Wave hub to monitor this device with your smart speaker if this functionality is supported in the integration.

• Z-Box Hub
• compatible with SmartThings
• Home Assistant (Z-Wave JS)
• HomeSeer

ADD Z-WAVE TO SMOKE AND CO ALARMS: Wire the DC Signal Sensor to your interconnected smoke and CO detectors and receive deticated notifications if either of them is triggered. NOTE: This is NOT a security alarm component and the device is NOT part of a life-safety system. Check local regulations before installing. Check Z-Wave compatibility first, this is an advanced device supported by selected hubs only (scroll down for details).
OPTIONAL RELAY CONTROL: Utilize the 120 V relay to add smart control of lights or siren as additional functionality. Do NOT use for other low-Voltage applications. This device comes with SmartStart for quick and secure network inclusion.
LONG RANGE READY: If your hub and automation software support Z-Wave Long Range, you’ll get extended coverage without network lags and dropouts! And for traditional set-ups, the built-in signal repeater keeps your mesh networks stable and fast.
EASY INSTALLATION: Pigtail wires included to save you time when wiring the dimmer for an hassle-free set-up. This product is backed by a lifetime US based support from Zooz and a 5-year warranty once registered.
HUB COMPATIBILITY: This is an advanced Z-Wave device and it requires an updated Z-Wave hub to display correctly. It was tested to work well with the Z-Box Hub (recommended for Zooz devices), Hubitat with custom driver, Home Assistant (Z-Wave JS), Ezlo, and it’s compatible with SmartThings through a custom edge driver (available through the Zooz support portal).
