InkbirdSmart Thermometer, Freezer Wireless Thermometer Bluetooth Temperature Sensor, with APP for Android and iOS (Detects Temperature ONLY)

Every RVer should have this Thermometer. I am so paranoid that the food in our RV fridge will get warm and spoil on our trips. This gives me the piece of mind knowing I can check the temp at any time. There is even a setting to notify you if it goes below a set temp.

Used it in our cooler during camping and it worked great!

Not happy with the product at all. After the initial setup my phone does not connect. Why does this product need a different app then the Inkbird app that I use for my grill thermometer? I am starting to wonder if this is even the same company as the inkbird grill thermometer is a far superior product in terms of reliability.

I got this as a way to gather temp data over time, for testing an old mini fridge. I am converting it to use as a fermentation chamber, being controlled with another Inkbird product, the ITC-308, and wanted to see how well it was controlling the temp. The other Inkbird does report temp, but at 15min intervals, which wasn't so good to see fast changes.This one works well for keeping close track of temperature. I like the feature of changing the sampling time, though the temperature time constant is probably larger than the >1minute time. It will store 3-4 days at 1 min sample rate.Good things about it:Like the small size, easy to place. The magnet also, can help with mounting it.I like the ability to export out data to csv files, for graphing in Excel.Setting up in the app was fairly easy, and it's easy to set alarms.Accuracy was pretty good, within about 1 deg from my "dependable" thermometer.Things I didn't like:No way to adjust or calibrate the temp. (that I found) It's pretty good, but if you're really a fanatic for accuracy it would be nice to get it spot on with a reference.Range was somewhat limited, when inside a fridge or freezer. Somewhat to be expected for radio inside of a metal box, and Bluetooth is a low power radio. The app needed a good signal to download history. Interestingly, just the current thermometer reading in the app seemed to update from farther away than the range you had to be in for a graph download.I was a bit disappointed that there wasn't an audible alarm in the box itself. Only the app will give you an alarm. I don't know why I expected this, was thinking it would be a good backup for temp failure in a fridge or freezer, maybe I was thinking of the ITC-308 controller, which does have it's own self contained alarm beeper.App is a bit fiddly in some areas. Was not able to find this device in the "Inkbird" app that I use the ITC-308 with, even though it looked like it should see Bluetooth devices.Overall, very useful for checking temp over time. Measure a room to see the high and low temp, and how much time it spends inbetween? Check your fridge and freezer to see how much the temp swings and how often? You now can easily do these things. I found out that our home fridge/freezer swings as much as 4-8 degrees (!) over it's on off cycles, while my mother-in-law's one barely moves 2 degrees.

These little devices work as advertised. The Bluetooth is great. I am able to check them from 40 feet away while they are inside my fridge. I bought one for the fridge and one for the freezer and the work great. The app is simple to use and that is a great benefit. No need for a 10 page manual to use them. 👍

I want to give this a good review but for my purposes I can’t. I purchased this unit to keep track of my freezer’s temperature as we keep a quarter of a (very expensive) cow in there and I wanted to protect my investment. So, I’ll keep this short and simple. Does it work as described? Yes. The unit and the app work well together. However!!! The unit has to be within a few feet of the phone for the signal to be picked up and give you an accurate reading. So, for me. It’s useless as my freezer is located in the basement. I literally had to go to the top of the basement stairs and sit for a minute for the signal to work on the phone app. (The app works great by the way, but only if your right on top of the unit. So I cannot recommend this product.) I honestly can’t see any use for this product unless you use it in a kitchen refrigerator and always keep your phone nearby.

The Bluetooth range is not as long as I had hoped. About 50 feet of the line of sight and 20 feet or less if an inside wall is in the way. It does not like to automatically reconnect and send data to the phone after it has been out of range. It seems that you must sometimes stop and restart the app to get it to reconnect and even if reconnects with the app running you must open and close the specific device to get it to upload data to the phone. I would say well if communicating with a fixed device that stays always within range and if you are checking your data frequently by opening the device file. Otherwise sort of a PITA. The individual devices do have several days of internal storage, but sometimes it is necessary to open and close the device even while staying in range in order to get all of the data if you have not uploaded it in a few days.

This little thermometer is the gift that keeps on giving. I have a freezer in an out building that I wanted to monitor and this has solved my problem. I’ve been using it for about a month now and it has worked flawlessly. I have it tied into my home automation system and I can see the cooling cycles and it alarms me if the temperature goes to high ( as in I left the door ajar). This is a great value and I’ll be getting a second one as I’m planning on adding a second freezer.
