Review on 🔥 X-Sense XS01-WT: Wi-Fi Enabled Smoke Detector with Replaceable Lithium Battery & Silence Button - Smart Fire Alarm for Enhanced Safety by Lance Foster

They are not connected. A fan of fire starts in a distant room without you noticing. Also, app-based alerts are destroyed by the Smart Life app because it cannot tell the difference between device types. Warnings: all or nothing. Therefore, a light that does not turn on sends the same warning as a fire alarm. It's useless. I ended up buying a Wi-Fi siren as well and dedicating it to this purpose. However, remember that all of this requires a working internet connection. At least in this case they work as normal smoke detectors again.
