4-Pack WiFi Temperature Humidity Sensor: Wireless Temperature Humidity Monitor with App Alert, Free Data Storage Export, Smart Indoor Thermometer Hygrometer Compatible with Alexa Google Assistant

Monitor the temperature of your abode / boat / mansion/car/anything other from afar. This item connects via Wi-Fi and keeps consistent temperature monitoring at your fingertips. Application is easy to use and the item is well made and it's durability. This system detects temperature and humidity and can give you a readout in Celsius or Fahrenheit. Functionality varies you can simply get the temperature or you can go to the extreme and allow trigger points. Such as if your refrigerator gets a little too warm due to the climate that you're in it can automatically turn on the air conditioner to cool the ambient air to help the fridge work less hard. You can set warning cues if the refrigerator or freezer is getting too cold and or too much moisture persist in the air. This little Wonder resolved my issue regarding refrigerator temperature in a 25 plus year old fridge. Note; unit comes in nice packaging and works with the Smart Life app. In the packaging you will receive two-way stickers/installation and program instructions and the thermometer. The battery case in the back is the actual mouth bracket and has access points to screw in or use adhesive to a wall.

We bought these to put in our camper for the main purpose of keeping an eye on the temperature inside while we were gone during the day. We wanted to ensure our pets are safe and comfortable. It has worked flawlessly! They are small, but durable, with a design that provides quick placements.We used double sided strips to place them in the front, middle, and back of our camper. They worked so well, we took the fourth and placed it under the camper to keep a check on temperature to ensure it didn't get cold enough to freeze our pipes during the winter.Connecting the to wifi was a breeze using the app and we have had no connectivity issues. But if the wifi does go out, they do not work. I've had to leave work a couple of times when I opened up the app to find them not working so I thought there was an issue (power out), when it turns out the wifi was down or router became unplugged. I wish there was a way for the app to say there was a wifi error.It's nice the app shows you the temperature and humidity, as well as tracks it so you can see it over time.This was a blessing and well worth the price I paid for it. Will buy more of these ever go out.

BUYER BEWARE! I purchased this unit from "SENCKIT" on Aug 21. By Dec 6th - it completely stopped working. I won't again buy from this company.For the 3 months & 1 week that it DID work - i had it in our bedroom and it appeared reliable - but i had to change batteries every month.Then on December 6th - my Senckit Temp Sensor simply stopped. Not a clue why.What do i mean by "stopped"? When i ask, "Alexa, what's the temperature in the bedroom?"Alexa says, "Bedroom isn't responding. Try checking its network connection and power supply."So i fired up my bluetooth & ran through all the "Fix Protocol" as follows:i remove and reinsert the two AAA batteries. That doesn't work.I press & hold the little reset button for 5 seconds. While it's held down it lights steady Red; and after 5 seconds when i let go - the light goes off.So i press & hold for 10 seconds. When i let go - it stays ON / steady red.It never blinks; it only stays on steady - and during this time, never any connection to Tuya app.Similar attempts with the "Smart Life" app, and the Senckit Temp Sensor doesn't connect there either.I tried new batteries. No dice there, either.I tried double-clicking the reset button - that didn't work.I tried changing the WiFi network. Nope!I asked around in this page's "Customer Questions & Answers" area - and i got NOTHING. Not from Customers; not from the manufacturer 'Senckit'.Ultimately - i threw my Senckit Temp Sensor in the trash where it belongs (glad i remembered first to rescue my fresh AAA batteries!)Learn from my mistake! I wish i'd not wasted my money on Senckit's plastic junk! :(

Inexpensive, wireless, easy to use devices. After 4 days the performance is satisfactory for the sensors. The app works pretty well, but is not quite as user friendly as I had hoped. In addition, there is a subscription feature for SMS or phone alerts. I signed up, but the alerts have not been coming even when they show up in the app.
