X-Sense Wi-Fi Hygrometer Indoor Humidity, Smart Thermometer with Remote Monitoring & App Control, an Accessory for STH54 Thermo-Hygrometer Kit, Model STH51

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.

Overall easy set up, good connection, work great.General:1. Every item has an easy step up.2. The range seems to be great. I've installed some smart switches, smart bulbs, and outlets that are quite touchy and don't have very good range, but not these. Seem to come right back when we loose power. Knock on wood, we haven't had problems with them going offline.3. I saw a comments that you can't assign multiple accounts to the base station. This true, but you can put them all on one account and share them and that works fine. Note that the Mailbox Alarm and Hygrometer/Thermometers all share when added to the base station. For the Cameras you have to share each one individually.4. These units all take "normal" batteries (triple or double AA, can't remember which) except the camera which have built in lithium rechargables. The app shows the battery strength which is handy.5. I think the dashboard would be better if you had an option to see a tabular (spreadsheet style) display, especially if you have a lot of devices. App in general works well, but could be better.6. No subscription required to get functionalityMailbox Alarm:Our mailbox is over 200 feet away and there is no line of sight, so I was concerned this would work but no problem.Hygrometers/Thermometers:These were $10 off for 3 with a base station, so that was cheaper then buying them individually. We have them outside (On a covered porch) and all over the house. We use some fans to move air from a finished basement to the upstairs to cut down on the AC. These have helped us improve the placement. Has an export data function, but I haven't tried it yet.Cameras:1. You can get a cloud service subscription, but you don't have to. Motion sensing works great. At medium it triggers on people but not the cats.2. We are mostly shady, but the solar cells seem to draw enough to keep the cameras charged up. You need to get a SD card per camera if you want to store and retrieve.3. The share function requires more steps and has to be done for each camera. Seemed to lag from when you shared to when you could access, but they all eventually worked (maybe 5 minutes?). Could be because some where updating firmware.4. These work where other items were not able to get on the WIFi.5. There is some lag in the motion alarm and the actual motion.6. You get a mic and speaker on each camera. Work fine with few second lag.7. Each camera takes it's own SD card. Supposed to be able to download, but I haven't found that.8. Viewing the recorded videos is 3 steps in the app (Click camera, then gear, then history) Would be better right Camera click. Not the greatest for picking out recordings (you have to scroll a line to a dot) but it all works.

Wow - I'm very impressed with this X-Sense Wi-Fi Indoor Smart Hygrometer Thermometer. I bought this to enable me to monitor remotely the temperature inside my lake cabin during the winter months when I am away. Sometimes the heating system goes out, and now I can have peace of mind that I am notified if/when the temperature in the cabin reaches levels near freezing. The set up of this system is made very easy, thanks to the great instruction booklet (with Q-codes) and the great app that you load onto your cell phone. Total setup time for me was about 3 minutes. Since setup, the system has worked flawlessly - no dropped internet router connections, no dropped sensor connections, etc. The system comes with everything needed - cable, AC power adapter, batteries (for the sensors), etc. For the price, this is an incredible value - especially because it comes with 3 sensors. Also, the system is apparently expandable with other types of sensors. Also - I like that this system has a separate base station which is A/C powered, which helps the batteries in the sensors last longer. It might be nice if the base station had an LCD display....but it's not really needed because the phone app is easy to launch and it displays all the info. Two thumbs up!

These were VERY easy to set up, and they have been working great. For most people they are acceptably accurate, within 1.5 degrees at 75 degrees. I'm more OCD, so I calibrated them to match a laser thermometer I use for reference. Overall, I'm very happy with these, but I do have a few minor complaints with the app.1. When the temperature went over one of the set levels, I instantly received a notification. This was exactly what I needed and it was the main reason I bought these. But a few seconds later I received another notification that it was back in range. For the next two minutes I received about 10 messages reporting that it was out and then back in range. A little annoying, but for me, it was a small price to pay to know that I could count on them to notify me when they were out of range.2. Some of the text within the app is too small and printed in light gray making it nearly impossible to read.3. On the Home Screen the Base Station shows up first, but it doesn't need to be accessed very often, if ever, and it should be positioned last. The thermometers show up in the order they were added, but that's not the order I want them to be in. There doesn't seem to be anyway to reposition them.These are small issues, but it cost them one star.

Really loving this! Very helpful to see the temps in my greenhouse!

Use these in our motor home. They seem to be working. The app is great so we can monitor conditions remotely. The data seems to be correct.
