AMIR Fridge Freezer Thermometer, Indoor Outdoor Temperature Monitor

Here's the best review I can give at this time. Received unit and put fresh batteries first in base unit, then added batteries to each of the two sensors. All three sensors registered good temps within 10 seconds. I placed first sensor in deep freeze and second out in a unheated area. After stabilization, all 3 registered temps that were consistent with mechanical thermometers I already had in each location. I placed the main unit upstairs in living area, not far above the two remote sensors downstairs - separated by ~ 1" of floor material and R30 insulation, and the freezer sensor inside the freezer compartment. Both stayed connected to base unit. Contrary to an earlier review, all 3 sensor channels have independent and settable alarm settings. Base channel is intended as an indoor sensor, and the alarm settings are settable from -9C - 60C - if that doesn't cover most living areas, well you're hardier than me! The remote sensor channels are settable between -39C - 60C - totally suitable for most household deep freezers. Alarm limit setup is fairly straightforward - hold down the appropriate key 3 sec. for the channel intended, set the high limit, hit same key once, and set low limit, and hit same key once again. You can do this for each channel, including the internal/ base unit sensor - just stay within the limits stated. When the main display is on, the numbers displayed on the right may seem confusing, but they are simply the highest and lowest recent temps registered on that channel. Hit "Clear" once (Short - once), and they will reset and start registering recent temp changes again. WARNING: If you hold down the "Clear" key for 3 seconds, it resets everything and starts the process over - you may have to do that to reacquire sensors after replacing batteries, but will just cause you additional work otherwise! It would have been less confusing if there was a key to display "recent" vs "set alarm settings', but there's not. If you want to review your alarm settings, hold down the appropriate "Alarm Setting" button for 3 seconds. If the Hi limit setting is what you want for the hi limit, then hit same key again once (don't hold). If you wish to make a change, use +/- keys to adjust desired change, then hit same key again once. That will put you into the low alarm settings mode. Again, use +/_ keys to set to desired lo limit, or do nothing to keep current setting, then hit same key again and all settings you viewed are saved. NOTE: You have to set and/or view all alarm settings individually by sensor channel - all 3 are independent of each other! Actually, pretty straightforward and it works, and the instructions are accurate, albeit busy. But that's typical for any device that is performing multiple functions and few keys to program with. I found this one far more straightforward than so many other devices that require pressing multiple switches to perform necessary setup. As for alarm volume, you won't hear it unless you're nearby - that is why I placed base unit up in the living area. Yes, it would be nice if it were louder, but given the physical confines of the base unit, it is what it is. It was audible if I were nearby but it's not going to wake you up, or likely to be heard over loud ambient noise - but it is audible. This is a common complaint for most residential temp monitors on the market and I guess it is just a case of "when's the next best thing coming"! This one isn't any worse than others I've dealt with. Long term, not sure how battery life will be for the sensor inside the freezer compartment. Each remote has a battery condition reading so at least it can be monitored. I have 3 deep freezers at my place, each in remote locations, but 2 of them are visited frequently. I bought this one to monitor the one I don't visit that often but it holds a lot of valuable meat I would hate to spoil. The other two I have small lights plugged into the GFI outlets so I can do frequent visual checks on them - GFI's seem to be biggest culprits of things shutting down, especially if you experience periodic power outages. For the $$, this unit is working well for it's low cost.

Review: good unit. Things that will confuse you at setup: many. You'll need 4 AA batteries and two AAA. Power up the remotes first. A few minutes later power up the base unit. The order of the reporting screen on the base unit is: Sensor 2 ------------ Sensor 1 ------------ Main unit That will confuse a few who aren't paying attention. I cannot stress this strongly enough, if you're using this the way I am, to monitor fridge and freezer temps, put the sensors where they will be, and... Walk away. For a couple hours, just go away. Don't set any alarms until the remote probes are at the temperature range they're going to live at. Reason: they will be outside of the temperature range you just set, so they will alarm. Over and over and over... So don't tell them the range until they are already in the range. When you program the minimum and maximum temps for alarm purposes, the number you are programming stays there while you're programming it, then disappears FOREVER, being replaced by the current min and max recorded since the last push of the CLEAR button. This is by design. To program high and low alarm limits: 1. Hold the alarm button until Max limit flashes. 2. Use + and - buttons to adjust (NOTE: As soon as you are done setting it and move on to the min limit, the display reverts to actual temp. There is NO way to "see what it's set to") 3. Tap the alarm button to move on to min limit setting, repeat process to set that limit. 4. One more tap of alarm button to finish up. To silence an ongoing alarm, first determine what's alarming. The alarm icon will be flashing on the affected line, and the temp will be outside of limits. Simply press the alarm button and release to silence. If you press the button while the alarm is sounding, it silences. If you press it while it is not sounding, it will turn off the alarm altogether. Answered questions: YES the sensors somehow find a way to send a signal from a steel box to a unit outside the steel box. I'm assuming it gets thru the door gasket. YES it appears to function just fine for this use. YES Battery life is good. The display units' batteries failed after several months, when it started going off day after day for too cold in the freezer, but that was hours and hours of chirp-chirp-chirp-chirp over several days. Based on similar stuff I have outside monitoring my weather over Wisconsin summers and winters, it shouldn't chew thru more than a set of batteries per year per sensor. YES, in my house at least the signal from the remote probes is strong enough that I can move the base unit to the kitchen on the first floor, instead of sticking it on the basement freezer, where I'm less likely to hear an alarm going off. Your mileage may vary in that regard but feel free to test. Others mention a backlight in the unit, I don't see one. So you'll need your flashlight to see the screen if the power is out and you're wondering whether your ice cream is still frozen. I WISH the things talked to my Tuya app so I could monitor it from anywhere and silence alarms from anywhere, and all that, but it doesn't and it doesn't have to. Still very happy with this unit after several months.

Temperatures seemed accurate. Receiving unit/display failed after 2 years.

BOTTOM LINE: Affordable, simple way to monitor the temps in your refrigerator and/or freezers to insure that your food stays at the temps it should. Pop in batteries, set upper & lower limits and forget it. About as simple as it gets. Very happy. Well worth it for the peace of mind. 5 STARS THOUGHTS: Having just filled our large chest freezer in the basement with a half Angus beef, I thought it might be a good idea to make sure things are staying at the proper frosty temps. Our freezer is decades old while it's always just chugged along without complaint, you just never know when it might give up the ghost. That'd be a helluva lot of perfectly good food (and money) gone to waste if it ever did. We don't go down there to pull food out or check on a daily basis so, after some internet researching, this inexpensive little remote thermometer seemed like a good way to keep tabs on things. As a bonus, this unit is set up for two individual sensors/monitored readings, so I placed the other sensor in the bottom drawer freezer in our fridge in the kitchen. Now they're both being closely monitored, so hopefully we'll never have any ugly surprises! Instruction booklet was helpful, but setting was an intuitive deal. Set upper & lower limits, decide whether you want an audible alarm for each sensor (about as loud as most cooking timer alarms) and place it where it's most convenient for you. (Receiver unit has a hole to allow for mounting on a nail or screw, a pop-out foot to allow you to set it upright on a counter or widow ledge, and 4 strong magnets so you can attach it to your stove or fridge. Main receiver unit takes 2 "AAA" batteries, remote sensors take 2 "AA" each. The manufacturer recommends using lithium batteries, for longer life. I'm not sure if regular batteries would last very long sitting in the single digit temps of the freezers, so I sprang for a set of Energizer Lithium batteries - just to be on the safe side. *** I also wanted to mention that when I got mine, I couldn't get a reading from Sensor #1. I tried different batteries and whatnot, but to no avail. I contacted the vendor (AMIR) and they quickly & politely responded with several suggestions, which I tried... but still no soap. I emailed them again and they offered me a complete refund and asked if I'd be willing to take a chance and re-order. I did, and within a couple of days the replacement arrived. When I put the batteries in, I quickly discovered that the fault with that first, original unit wasn't with the remote sensor but rather the main receiver/display monitor; the readout for sensor #1 was dead. Oddly, they said I didn't have to bother returning the defective original. So now I have a second one which only displays one reading, but rather than throw it away or let it sit in a drawer I simply used the fully functional replacement unit to monitor our freezer AND fridge upstairs, and now that original unit with only one working temp is dedicated to the big downstairs freezer. Now I can keep tabs on EVERYTHING being kept chilled or frozen. Win-Win! THAT is what I call outstanding customer service!

Worked for about a month and now won't stay set to any temp. Literally changes to a different temp after you set the temp for the alarm, and then goes off at another temp. Garbage, do not buy

I’ve been waiting to write this review. It took me forever to figure out how set the temperature on both the freezer and the refrigerator. And this spread this thing must know when I’m either walking in the house or when I’m going to sleep at night because as soon as I walk in, it’s going off and as soon as I go to bed and finally get to sleep it’s going off and when I get up and go check on the refrigerator as well within range and the freezer always is in with range. I bought it because my refrigerator is always going down in the apartment complex has already had to get me to refrigerators and they always say well you’ve done something wrong so I got tired of hearing it so that’s why I bought this but my goodness this thing keeps me up all night long. I’m having to get up and down all night long in the middle of the night to turn this stupid alarm off so I’ve just got to work. I’ll just put up a big case of Mountain Dew or a big case of water in front of the refrigerator because the fridge isn’t open I mean my fridge the temperature on it was 28 so it’s working everything’s working right so y’all do with that what you will it’s a good it works well thing works all right but the stupid alarm keeps going off and off and off. It’s driving me nuts.

This isn't a "smart" thermometer in any way. And the biggest problem with this (there are a few issues) is that you lose your settings when the battery dies at the base unit. You may even lose communication with your sensors. The alarm is persistent (good in one way) but definitely annoying after hours. The unit does what it says it is supposed to do. If the sensors talk to the base unit. Range might be an issue to address connections. The sensors are small-ish, unobtrusive (Maybe), but they're a clip and they may just be in the way. Or not be where you want the sensor. After about the 3rd base unit battery swap and loss of programmed limits, I stopped using them. I'm onto a different monitoring option soon.

I have had this installed in my refrigerator for a year or more and it has worked flawlessly. It is reassuring to know that your food is being stored within the safe temperature limits. It is also good to be able to see what effect having the refrigerator open a lot has on the temperature. It seems many refrigerators these days are designed for energy saving and barely have enough cooling capacity to get down to the necessary temperature. I don't know how long the battery will last, but already it is longer than I expected. It has to transmit a signal from the sensor inside the fridge to the display on the outside. The display has a magnetic back. It has worked well on my fridge to hold it in a convenient spot.

U always can C what the freezer temps R

For the price, this is quite amazing. The build is very solid, no flimsy plastic. The measured temperatures are accurate and sensitive. I was worried that I might have trouble with the sensors connecting to the display as my house is notorious for poor WIFI reception. But I have had zero issues with the two sensors in the basement connecting to the display on the main floor. I wish they made WIFI access points!

I have an overpriced fridge with a lot of electronic crap I really didn’t need. One thing it tells me is what the temperature is set at but doesn’t tell me the actual temperature or warm me when it not cooling properly. After a power surge blew the compressor it was cooling off and on, so I bought this to monitor the internal temperature. Only thing I have against it is you have to look at a specific angle to clearly read it, but was easily fixed by moving it lower on the fridge

Works great, Much better looking than the Acurite models. The local temp is an added bonus. it is accurate, I have them with a second probe to validate. Have to use the TOP quality batteries, you need to use Lithium battery in the sensors other wise they will die in no time because of the cold. Displaying the Last known value when resetting the display is great but you can't validate that the sensors are working. The old Acurite would blank the display and wait for the next measure from the sensors. For the price it pack loads of features. let's now see long term if the sensors will last. Side note, the remote probe are Acurite look a like.
