Handy Little Temp & Humidity Gadget That Just Works
Bought two of these small sensors last month, one for the baby room and one for the wine fridge in the garage because I’m tired of guessing if things are staying in range, set them up in like 30 seconds each, just opened the app, scanned the QR, done. Readings update every 10 seconds and match my old digital thermometer within half a degree, pretty spot-on. I stuck one on the wall with the included adhesive and the other just sits on a shelf, both stay put and look clean, no giant display screaming at you. The solar strip thing actually works, even under regular room lights the battery still shows 100% after four weeks, haven’t touched a battery yet. Went on a long weekend trip and left Bluetooth off the whole time, when I got home everything synced instantly and I could scroll back day-by-day to see the garage never went above 72, nice peace of mind. App is simple, graphs are easy to read, and I set alerts so it pings me if the baby room drops below 65 at night, came in handy once when the heater acted up. Couple nitpicks: the app only shows one device at a time on the main screen, have to swipe to switch between rooms which is kinda annoying, and in total darkness the screen goes completely blank, you gotta tap it or shine a light to wake it up. Still, for the size and price these are way better than the chunky ones I had before, already ordered a third for the reptile tank, definitely worth keeping around.

Works Great
The setup was simple, and I like that it connects right to my phone. The app shows all the little details, temperature, humidity, trends, and it even stores info offline, which is nice.What I like most is being able to check everything in real time. Whether I place one in a storage room or near a pet area, I can see exactly what’s going on without having to walk back and forth.The solar design is a bonus too, because it cuts down on constantly changing batteries. It’s compact, clean-looking, and blends in anywhere I put it.Overall, I’m really happy with these. They do exactly what I wanted, and the convenience of the remote app control has already come in handy more than once. Definitely a smart little addition to the house.

Placement is important for accurate readings
I have a thermometer/hygrometer that has been really handy, so I ordered a different one for another area of our cabin.I tend to be very literal, so installing batteries in the “solar” thermo-hygrometer felt a bit contradictory. Full disclosure, I struggled with removing the battery cover because, again, I’m very literal. For anyone else like me, don’t lift it diagonally, or try to slide it, or twist it. Just pop the back straight off.This little device taught me placement is key. I set it near my other unit to verify the readings and they were off by a couple degrees and few percentages. I didn’t know which one was off and, honestly, didn’t want to order a 3rd, so I placed them side by side and realized that few inches was problematic.

Works perfectly
When it comes to telling and checking the humidity, I actually find this really easy to use and monitor. The app is very user friendly that I can not only just see the humidity but also the temperature too. When it comes to the range, I can be in another room and I’m still able to connect to this monitor real easily too. Great range, so far. The whole system was super easy to setup and I like that this came in a 2 pack because I can have one on one side of the room and the other on the other side. Even with dealing with humidity, these are still working just as they should and show no signs of damage from the humidity in the air. Really sturdy and so easy to use.

Bad outside reading
The outside unit has to be set in the right area. I placed in one place, and showed 20+ higher then the real outside temp

Compact size, reads accurately
It detects and displays humidity and temp levels accurately. Its quality is phenomenal. I got the two pack for a good price. It reads well. The size is very tiny good for desk top use. Its range is shown from wet to dry and is easy to quickly read.

Must have for family with eczema
Kid’s pediatrician recommended me getting a humidity monitor for eczema. And I’m very glad I did and bought this product.This is perfect for large New York apartment building with central heat supply. I can easily monitor kid’s room temperature and humidity through the app. Which means no more worrying and walk into their room open their light just to check on the humidifier and temperature. Oh. It also comes with batteries which is a big plus since I have none at home

Accurate!
Pretty accurate! Took a couple hours to get it to acclimate but it shows exactly what my house thermostat shows. App is really easy to use. Very happy with purchase. In the app, you can also adjust the temperature based on a variance, so if it’s reading 34° when it’s actually 36, you can adjust it accordingly to give you an accurate reading.
