X-sense WiFi smoke alarm that does not work My problem is with a smoke alarm which is marketed by a company calling itself ‘X-sense’ the alarm purports to function wirelessly, it does not, I have contacted the company for help but have just been fobbed off each time. I was going to review them on Amazon which is where I bought it but they, or Amazon, are blocking reviews hence the review is here. According to what I get on Amazon X-sense do not exist, no doubt another of the Chinese sellers who disappear when they get enough complaints and Amazon do not help as there is no way to contact them.

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.

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.

Shipped from China and customs duty is payable on arrival in destination country. Ordered X-Sense camera from the German website. They telephoned to say only available with US plug. That was OK for me. It took 25 days to be delivered from China (so the EU web site is rather misleading in that respect and should be more transparent). I was required to pay a customs tariff (in Spain) plus 21% VAT on the tariff. Total of 7.69 Euro so be aware of this additional cost which I assume will vary according to the destination country.

Customer Service Non-Existent We ordered two smoke and carbon monoxide detectors (built-in) that worked fine for a few months. All of a sudden, the two started going off randomly and would also go off during the early hours of the morning. You can imagine waking up to them both going off at 3am! I contacted X-Sense directly for advice, as i cannot turn them off without permanently deactivating them. It's been two weeks, and we still haven't heard back from them. It was quite urgent as they kept going off all day and night randomly. I cannot honestly recommend X-Sense as the customer service is non-existent, and the products, well, what can I say.
