X-Sense Indoor Wi-Fi Thermometer Hygrometer, Base Station not Included

This temperature sensor solved a problem for me that I've been struggling with for a very long time. I have a tuck-under garage, which has a bathroom on top of it. That means it has plumbing that runs through the garage. I also live in Minnesota, where the temperatures can drop to extremely low levels. Although I have heat vents in my garage, they are not fully open since the garage does not need to be heated to the same temperature as the rest of the house. This was kind of a pain to deal with, and twice since 2007, I've had to deal with burst pipes because of it. Well, now that I have this temperature sensor, I think those burst pipes will be a thing of the past. I can set a low temperature warning, and be notified if my garage goes below that temperature and heat my garage before the pipes burst. I also have several X-Sense water leak sensors in my basement, and this temperature sensor is compatible with the same base that the water leak sensors use. I found the app very easy to use, and the instructions for setting up the sensors to be very easy to understand. When the heat sensor detects a lower temperature than you've set in the app, it plays an "alarm" sound (it plays a tune, and not like an ear-piercing tone) on the base and sends you an alert on your phone. If I have any complaint, it's that the alarm doesn't seem to repeat. It only happens once, so you might miss the sound and not see the alert for some time. I'm not sure if there's any way in the app to change this, but it might be a feature they could add in the future.

Installed seven of these units at the end of October last year. I needed to monitor the temperature inside the house while away during the worst part of winter when the temperatures dipped down to 9F. All units performed flawlessly even though some were three floors below the base station and roughly 50’ away with floors and walls in between. Unlike similar products from competitors these were always on line and reporting the temperatures at their locations. These units also have the ability to set alarms to let you know immediately on your phone of temperatures falling below or going above your set points. Everything worked flawlessly. This was certainly a good investment, speaking of which, the price is very reasonable.

Really enjoyed the mailbox sensor that started me with X-Sense and got me the base station, so was keen to try the thermometers after another freezer disaster (unrelated). We have two fridge/freezers, so I got three sensors plus an extra STH-51. The user experience with the app and sensors is really excellent. And since installation earlier this year, it's already saved us twice with accurate and timely temperature alarms when appliance doors have been inadvertently left open. I was initially potentially worried about the low temperature range and battery life, but both have been no issue at all for domestic appliance temperatures and regular batteries last months. Love our X-Sense system!

I got this to monitor temperature in my RV. I have several other X-Sense products in the RV.I like that I can monitor it from one app and set alerts for when I’m away from the RV. This is a much more cost-effective solution to those expensive subscription services. Work it works perfectly.

This is a great product for remotely monitoring temperature and humidity. It works exceptionally well, is a breeze to setup. The app supports multiple base stations as well so you can have multiple locations if necessary. For me, I have 2 base stations — one that I use to monitor my barn, farm office, and greenhouse, and the other that monitors my beehives — I place the sensors inside the hives. I do wish the thermo hygrometer sensors were a bit smaller, like Govees, but other than that have zero complaints. Battery life is very good. App performance is excellent and can easily view timeline trends per sensor by day, week, etc. A trend line report that would show all of a base stations connected sensors would be nice but there isn’t one currently. I have not tried any of X-Senses other sensors or safety / smoke detectors but if I had a need wouldn’t hesitate to add them to my systems.

Update 7/9/26: I heard back from their customer service and they confirmed the 10 hygrometer/thermometer limit. It was also listed in the post details, but I failed to see that. The only work around is to buy additional base stations and set them up as an additional “home” in the app. This doesn’t sound like a very user friendly interface so I’m going to look elsewhere. The frustrating part is that when you buy the bundle, you essentially get the base station for free. Had I known this limitation, I would’ve bought a different product, or bought more of the bundles rather than individual sensors. There are a couple Govee options that I will try next. Pros: The STH0B Smart Thermometer Hygrometer seems to be reasonably accurate. The size is very nice. It’s a lot smaller than other units is looked at. It is very easy to connect more modules to the base station. Cons: You need a base station to use the STH0B units. Although, at this price point, that seems reasonable to me. The app limits you to a maximum of 10 thermometer/hygrometers. The website says the base station supports up to 50 devices, but it doesn’t indicate that only 10 of those devices can be thermometer/hygrometers. I specifically bought these to check the humidity in 20 different storage containers. And now it’s too late to return the base station and first batch of sensors. I will update the review if I find out they are able to resolve this issue. But at the moment, this seems like false advertising to me.

I have six of these monitoring my fridges and freezers, both for personal use and my chicken business. The only issue is that while they record under -4 degrees, the app only lets me set an alarm at -4, so unless I adjust the freezer, the alarm is constantly going off.

I had to replace one I had used outside and got wet, not knowing that it wasn’t waterproof, but this one’s working great. I have it right next to another temperature and humidity sensor that’s proven to be accurate and this one measures the same.

Este dispositivo solo funciona con una base que no se vende en Amazon México. Por tal motivo les recomiendo no lo compren a menos que ya la tengan. De lo contrario solo es un gasto innecesario
