What are the differences between the XS01-WT and XS03-WX smoke alarms?


XS01-WT: A smart Wi-Fi smoke alarm that can be connected to Wi-Fi via the TuyaSmart/Smart Life app. It sends alerts to your phone and lets you know what's going on in and around your home, even when you're away.

XS03-WX: A smart Wi-Fi smoke alarm that can be connected to Wi-Fi via the X-Sense Home Security app. Find out what’s going on in and around your home from the app notifications while you’re away.

What are the differences between the XS03-WX and XS03-iWX smoke alarms?

The main difference is that the X-Sense XS03-iWX smoke alarm needs to be paired with the X-Sense SBS10 base station, while the X-Sense XS03-WX alarm works independently via a Wi-Fi network. Once an alarm is triggered, all X-Sense XS03-iWX smoke alarms and base station will activate simultaneously, while the X-Sense XS03-WX smoke alarm will sound independently.

Is there a cost for the app?

No, it is a one-time purchase, and you don’t need to pay for the app.

How do I add more users to the app so they can all monitor the alarms on their phones in the X-Sense app?

Go to the smoke alarm’s Device Settings interface and select Device Sharing. Then enter the X-Sense accounts that you’d like to share with.

Do they have a light that flashes periodically and lets you know that the unit is on and working?

Yes, if your smoke alarm flashes red once every 60 seconds, it means it is functioning. For more details, please refer to the user manual.

How many Wi-Fi smoke alarms can be connected to the app?

You may add up to 24 X-Sense XS03-WX smoke alarms in one home. You may also give them different names so that you know which one has been triggered when you receive a push notification.

What will happen if the Wi-Fi is disconnected?

If your Wi-Fi is disconnected, the X-Sense app will display “Offline”. The devices will continue to work as standalone units, but you may not control them using the app. We recommend that you enable Offline Notification on your phone so you will know if the device is offline.

Why is it not accessing the Wi-Fi?

Make sure you have a stable 2.4 GHz Wi-Fi network and have enabled Bluetooth on your phone. Then add the X-Sense XS03-WX smoke alarm to the app. Please ensure that you connect to the same Wi-Fi network when you add the device to the app.
