This Company may be a scam - AVOID!! I'm not sure if this company is a scam. I ordered a CO2 detector which has never arrived. The tracking information I received directed me to a shipping company website in Chinese and I had no ability to change to language to English. I have sent e-mails and called customer service numerous time with no response - AVOID AT ALL COST

X-Sense XS01-W causes false alarms around the clock I bought 10 X-Sense XS01-W connectable smoke alarms and (after testing) installed these in a student home. Within a week, I got reports that these alarms went of in the middle of the night for no apparent reason. A week later, I witnessed this myself: I was in the house on saturday morning and all alarms went off, one after the other with a couple of minutes in between. The trigger each time seemed to be a different alarm. I took all of them home and put them on my desk. Within the day, I had the same experience (luckily not at night). I retested all of them, and found one to be defect (ie it did not react entirely as described in the manual when I tested it). But regardless of that, I think it is unacceptable that any defect would cause this behaviour. I luckily was able to return them, and now bought non-connected alarms again.

Good Smoke Alarms With Plenty of App Features We recently bought eight X-Sense XS01-WT smart smoke detectors & three of them have gone offline which should not be a problem. However, after going offline they have failed to reconnect to the router. Customer services did respond very quickly with advice on how to reset them & one detector did get back online but the other two won't & they don't respond to the button presses & beeps outlined in the guidance. UPDATE:The instructions were quite poor & didn't cover what to do if they went offline. Eventually I found, by trial & error, that if they go offline all that's needed to bring them back online is to press the test button for a second. The unit then goes back online & sends a notification to my phone.

do not buy I have tried to connect the base station to two seperate routers without success. Also I have tried to enter the information manually but the app requests a QR code or serial number but the base unit is blank with only the model number on. I have also entered the wifi password but the unit was unable to connect to the router although my phone and tablet were able to do so at approximately 30 cm away from each other. This equipment is poor quality and not worth the money avoid!

My review was removed My review was removed And this is unfair I really bought a sensor and a remote control And they are not working The customer service do not want to refund me Any way the product is not working together you can not stop the sensor with the remote control and the technical service told me that TO AVOID
