So, when the alarm goes off, and you are not at home, you will receive a real-time notification on your phone that gives you enough time to respond.

What are the features of the X-Sense XS01-WT Wi-Fi smoke detector?

In our X-Sense XS01-WT review, we found these features that make the Wi-Fi smoke detector an ideal unit for protecting your home against fires.

Photoelectric sensor

The unit comes integrated with an advanced photoelectric sensor that quickly detects dangerous smoke in the air.

Insect-proof screen

The alarm features an integrated screen that will prevent insects from damaging the unit. The screen ensures the alarm’s long-term accuracy, sensitivity, and reliability.

Lithium battery

The alarm has a 3V CR123A lithium battery that will work for only a year. You will have to replace it by purchasing a new one from the official store since it is unique.

Silence button

The alarm has a silence button that you can press to cancel false alarms that may occur because of kitchen fumes or cigarette smoking.

You can turn the silence button on using the app, especially when you want to test if the app is connected to the alarm.

TuyaSmart/Smart Life app

Since the unit sends you notifications on your phone, you have to install an app. The alarm uses the TuyaSmart/Smart Life app. You can download it for Android or iOS phones.

How to install the X-Sense XS01-WT Wi-Fi smoke detector

When you buy the X-Sense XS01-WT Wi-Fi smoke detector, you will get one alarm unit, a mounting bracket, two screws, two anchor plugs, a pin, and a user manual.

Once you have the items, here is how to install the alarm:

  • Use the mounting bracket to mark two screw holes on the ceiling or the wall.
  • Drill holes on the two marks you have made.
  • Insert the two anchor plugs in the holes.
  • Screw the mounting bracket using the two screws.
  • Attach the alarm unit to the mounting bracket.
  • Lock the alarm in by turning it clockwise.

At this point, test the smoke alarm to see if it works. You can test the alarm by pressing the test/silence button.

Expect the alarm to beep three times and the LED indicator to flash red and then flash blue rapidly for a few seconds. That will indicate the alarm has connected and will enter standby mode after the test ends.

How much does the X-Sense XS01-WT Wi-Fi smoke detector cost?

The X-Sense XS01-WT Wi-Fi Smoke Detector is an affordable smoke detector that costs only $39.99 on Amazon.

But if you want to pay less, you can buy it from its official store at $36.99. Note that the price is subject to change.

Is the X-Sense XS01-WT Wi-Fi smoke detector worth it?

After reviewing the X-Sense XS01-WT personally and comparing it with customer reviews online, it is definitely worth buying.

The smoke detector is accurate, convenient, and will send notifications right to your phone. Besides, it is affordable.

However, it is worth noting that you can’t interconnect it with similar smoke detectors so that an alarm sounds on each one of them whenever smoke is detected.

For this, you might want to go with the XS01-WR Link+ that has an 820 feet transmission range.

On the other hand, if you are looking for a combination smoke and carbon monoxide detector, you should consider the X-Sense SC07-W.
