X-SenseSmart Smoke Detector with Voice Alerts and 17 Locations, Wi-Fi Smoke Alarm with SBS50 Base Station, Test from APP, Wireless Interconnected Fire Alarm, Model XS0B-MR61GreenCircle Certified: Certified Energy Savings

I had a full house of new Kidde wired alarms that would not stop giving false alarms in the middle of the night. I threw them all out, replaced with these x-sense (6 smoke, 3 combo), and couldn't be happier. Firstly, no false alarms. The smoke units are nice and compact. Talking alarms state smoke location. The app lets me monitor the battery state and make sure all are connected. The hub allows IoT integration, in particular I use Home Assistant and can see all unit details. I also have a "smoke detector detector" unit for my burglar alarm (listens for the smoke alarms going off and calls the fire department), and these units are correctly detected.

Easy to connect the sensors together. You program each sensor to the room it will be in. When you test them, the room your testing from is announced throughout the house along with sounding an alarm. In case of fire, it identifies where the fire is. Great value for the money. Excellent safety for you and your family

These being connected and all going off together gives me a lot more confidence I’ll wake up to an alarm on the other side of the house down in the basement.These have been easy to install and connect and I feel like they are much louder than the standard Kidde alarms I have. It’s also nice to be able to test from the app without having to get out the step ladder. I got one of the combo alarms and it was easy to add to this base station. I’ll probably add another couple combo alarms to ensure I have extra coverage.Price wise there are not much more than regular “dumb” alarms so for piece of mind I would highly recommend.

I put this in our house and placed detectors in bedrooms and hallways. I love that all detectors go off if one is activated. We can't hear the one in the basement if we are in our bedrooms to flights up. The app is easy to use and I like that it will let me know when the batteries are getting low. No more playing marco polo trying to find the one smoke detector that's beeping due to low battery. I am getting a second set for our family beach house. It's a rental as well so I appreciate the extra layer of safety for our guests.

This is a nicely made system that is generally easy to install, assuming you have a working App to use with it. The detectors seem well made and are easy to install. The Hub installed and connected with no problem. Once the Hub is installed, connecting the individual devices to the Hub is straight forward and it is easy to confirm that they are working.The following issues were observed:1. You are very restricted on the voice messages indicating which alarm has been triggered. The voice cannot use any thing other than the pre-stored names which you do not find out until have you have given the location a name. Thus you are restricted to the names they have which may be completely useless for you for indicating where the issue is located.2. I invited my wife so that she could monitor the system, but the app version available in the app store (Apple App Store , v2.7) does not work on her iPhone 16 Pro Max. It allowed her to create an account but then crashes when she signs in and refuses to load. I had v2.6 installed on my iPhone 16 Pro Max which appears to work. I have prevented any upgrade on my phone as it may not work. This makes the system less useful. Also note that the way the application is tied to the system via the invitation is to make sure that the person who gets the invitations uses the same email address that was used in the invite. I cannot see this explained anywhere but I am not sure how it would work otherwise.3. It is very unclear whether the detectors are connected with each other if they are paired with the Hub and the hub fails or goes off line.4. The detector to detector pairing process is complicated although when packaged together in a set they are supposed to be paired without going through a manual process.5. The suggested types of detector (smoke, heat and carbon monoxide) are not available in a convenient set as per their typical suggested home requirement, which means you need to buy a set of smoke alarms and then buy carbon monoxide and heat alarms as needed, making the process unduly complicated and more expensive than first anticipated.6. The set I was shipped was already 7 months old thus reducing the life from 10 yrs. to 9 years and 5 months. It also means that the batteries may need replacing earlier than anticipated.7. One of the detectors had had the battery removed from the alarm (they are supplied with the battery fitted and a insulating film in place to prevent the battery making contact and activating the alarm) and the protective film that prevents the alarm being activated removed. I suspect my set was a return.In summary, this may be a reasonable system that is competitively priced but there are a number of issues that make installation and configuration more complex than it need be and the fact that the App would only work on my Phone is a serious short-coming.Update 3April 2025: App updated to 2.7.1 stopped the app crashing when an invitation is received but required the app to be deleted and re installed when devices added by another user.

Installed easily by following included instructions. Works as described! I've not tested it with smoke yet but otherwise all is great. Syncs fine with 5g wifi, not sure why they say it doesn't.
