Freezer Thermometer H5108

Too many negative reviews for such a really good thermometer. I bought this set that came with the hub and 2 thermometers. You can connect up to 30 sensors on one hub. I am now using 4 sensors. Install the app. If u get a message about an update then download it. Follow the directions and connect to your home wifi , 2.4 ghz only is supported. Once that is done move on to connecting the sensor. Open the app and click the plus sign in top right corner. Use search bar for this sensor. It will show a tiny picture of it on the app if you selected the right one. You will get a message to keep phone close to sensor while connecting. Once it is found u will need to depress the side button on the sensor one quick time for it to finish its connection and make sure your bluetooth is on your phone. In settings on the app you will see Remote View, click it. Next screen will show device and the word Bound. Click on Bound this will allow it to connect to your wifi through the hub. Setup is really simple. If I can get these to work in less than 5 minutes u can to. You can rename the sensor and adjust min and max Temps for alerts. Along with how long it has to be at or above the alert level u set before it sends u an alert. I am using these to monitor 3 deep freezers and in one refrigerator with no issues at all. All refrigerators and freezers have different seals and with all of mine I was able to pull the seal loose from the door and ran the cord under the seal and into the unit for a cleaner look. I am not a fan of a cord showing but it beats having batteries exposed to constant sub zero Temps and failing frequently. I have played around with the alert settings and they have not once failed for an alert to my phone. My hub is mounted up high in my garage. It fit perfectly in the outlet for the garage door opener in the ceiling. If u mount it behind the fridge or freezer it will more than likely get a weak signal. I am pleased with these and I do recommend them. The hub does not have a built in battery backup and needs to stay plugged in to constant power. The app is free and has no monthly fees. Lots of features in the app and easy to navigate through. Wish I had these on my freezers before I lost all the food in one of them while I was out of town. Lost about $700 in food, not to mention a nasty smelly cleanup job and all of it could of been avoided with this monitor system. Update. I recommended this to a friend that uses an I phone, they downloaded the app from the play store, don't do that, it wouldn't connect to the hub. Had to delete it and start over using the QR code on the instructions. Everything works now with no issues. Customer support is a real person and they were awesome in their service. These do work like a charm.

We came home a couple of weeks ago and my wife found that the product (mostly steak and sausage) on the top two shelves in our upright freezer were thawing. We had just stocked up on meat and were glad we found this out in time. The next day I ordered the Govee thermometer set based on reviews, remote monitoring, and alarm settings. When we received the items, the setup was super easy and straightforward. I like the flexibility in naming, adjusting the alarms and the various reports I can review. The thermometers are extremely accurate and I was initially surprised at how must fluctuation occurs in the refrigerator and freezer based on ambient temperature (garage) and its own internal threshold to cool. The magnets hold extremely well. The digits are easily seen by those people who don’t have the app. I have not had any problem with the range of the sensors in relation to the control unit. We did find that our initial location for the control unit interfered with our Wyze garage controller causing the door to open randomly. Once we isolated this as the cause, we just moved the controller to a different location in the garage and have not had any problems since. We often travel and we have family watch our house. This will be a great tool to add peace of mind. We are now considering buying water sensors for the same peace of mind if we have a water leak while we are traveling. It has a clean look that does not distract from the overall look of the fridge door. The multiple device report screen is really to my liking and is functional as far as getting the information I want to see without a lot of jiggering around.

Works great. Detects air temperature--not some hidden built-in thermometer) so you know if air is circulating and cooling. That does mean you will notice changes when you open up your fridge/freezer, but I find that a good reminder to close those doors promptly. The wifi let's you check on temps without leaving your chair, and the magnetic displays conveniently go right on the front.

Edit: At first I could not access the HS108 thermometers over the Internet via the H5151 gateway, despite following all instructions to the best of my knowledge. After resetting them and with some trial and error, I got them to work and their functionality is very good when working. The documentation and tech support could be better, though, as a quick five-minute phone call would probably have resolved some ambiguous instructions.

I recently (5-6-24) purchased the GoveeLife WiFi Freezer Thermometer Alarm 2 Pack, Remote App Alert. I can tell you it is easy to setup and use and is accurate as advertised. I have seen reviews about this device saying it can be hard to set up and there were issues with false alarms and the lower limit setting only went to -4 F. My experience with setup and programing went flawlessly. I just used the simple directions that came in the box. Download the app, plug the gateway into a receptacle, pull the battery disconnect tap out of the thermometer and plug the probe into it. Follow the directions and the app does all the work, prompting you for what to do next. Note, I was prompted to wait for the gateway to download an update, and then later for the the thermometer to downloaded one. I did not have to do anything to facilitate these updates except wait a few seconds for each one. As far as false alarms, you can easily avoid them by setting the time in the temperature alarm section on the slide bar to 10 minutes. That way if your temp rises when your freezer goes through the defrost cycle, or when you open the door to get something, or when you bring a bunch of groceries home and have the door opened for an extended period you shouldn't get an alarm unless the temp stays out of range for over ten minutes. After viewing temperature data for five days I found that my freezer temp never rose above 18 degrees and that was after shopping and having the door open for an extend time while rearranging and putting stuff in. Note, when I first set it up I just had the probe hanging on the door so when you had it open it was effectively reporting room temp after a few seconds. I moved it about half way back into the freezer and stuck it on side wall. Now I don't get immediate wide temp swings when we open and close the door. Reaching in to grab something quickly will produce a 2 to 6 degree temp drop and temp returns to normal within a couple of minutes after closing the door. I can actually look at the recorded data and tell when the door was opened or the freezer had a defrost cycle. As far as the lower limit setting, mine has a lower limit setting down to -40. This may be something that will change for the units that only have a -4 setting with an update. I set my lower limit to -12 and upper at 22. My data stream shows that my freezer runs about -4 to -6 when it the door stays closed and it isn't going through a defrost cycle. I think the 2 degree swing comes from the ice maker cycling because it heats the tray the cubes are in for release and then introduces water from the service line to fill. My probe is mounted near the area of the ice maker, if I moved it down a shelf or two it might not see this fluctuation. I likely won't move it as it is just more data about the normal operation of my freezer. This is a great way to protect your self from a food loss and a smelly mess. Not only will it send an alarm to let you know something has gone wrong but you can see by looking at the date occasionally if your freezer is not behaving normally before it become a big problem. You can also tell if someone is holding the door while they sneak a few spoons of ice cream! I bought it so I have peace of mind when I'm on a trip. If something goes wrong I can call someone to go empty the freezer, keep the food from going to waste maybe, and not come home to the kind of mess that would take a hazmat team to clean up. The price was also great considering you get two thermometers in the pack. Great product that I would buy again.

This works great for monitoring our two freezers in the garage! About two weeks ago we found our main deep freeze in the garage didn't close or seal right for whatever reason. We left for a couple hours and came back and everything was almost totally thawed out and filled with ice. Either the door didn't close, or the compressor stopped... Don't know. But I wanted something I could remotely monitor the internal temperature of this, and the freezer of our vertical freezer/fridge next to it. This was priced good, and seemed to have pretty decent reviews so I thought I'd give it a try. This just fits the bill perfectly and have to say I'm pretty impressed so far. It reads very accurate, within a half degree of an expensive, precision calibrated temp probe I have. Very easy to set up and the magnetic displays are bright, good contrast, and easy to read. I love I can see temps for both freezers quickly at a glance. The best part though, is it's app functionality and data monitoring and alarm. The app is easy to use, intuitive, and has tons of data, with graph for monitoring over time. You can set alerts sent to the app if the temp rises over a certain temp for a specified time. Great to have peace of mind always being able to see the temp instantly and get an alert of something isn't right so you don't lose an entire freezer of expensive food. I guess some people leave bad reviews for the app and setup, but maybe they're just not tech savvy or it's too overwhelming for them. Who knows, but if you're at all good with modern tech, setup and customizing everything is a cinch. Highly recommend!

Purchased this a few months ago, and have now had a chance to use it and see how well it works. In short - it works very well. Setup is easy (both installing and connecting the sensors to your home network, and configuring the app). The app in particular was reasonably intuitive, which is helpful. There are lots of app settings you can adjust, but the most useful for me is the alarms to alert you if the temperature goes outside a specific range (as in "oops, you left the freezer door open again"). This feature has saved me several times. I got a notification that my deep freezer was at 20 degrees - too warm, but still well in advance of when I would start to lose food. My only suggestion is that the instructions for the placement of the temperature probes could be better. I initially installed them near the top of the freezer cabinet, but that location led to lots of false alarms when the freezer went through its normal defrost cycle. I'd suggest installing the probes a bit down from the top instead. I have mine just above the second shelf down, which seems to be an ideal location. You can't get replacements for the brackets that hold the temperature probes (per Govee), but I was able to pry them off the cabinet wall and reposition them. The adhesive squares that come with the kit stick amazingly well - just make sure the spot you are attaching them to is dry, and you should be good to go. Overall I'm very happy with the units, and would definitely recommend them.

Have used the thermometer as directed for over 3 weeks. The temperature readings on the display are all over the place. -22 degrees to 1 degree all while the freezer has not been opened and is constantly powered. The app history is more reasonable (-8 degrees to 0.4 degrees) but even that is not within the mechanical thermometer's readings which register -2, -1. This is a waste of money. Don't see how some folks say it's fine unless they got lucky with their unit. Will try to return since within the return window but I no longer have the box it came in. Not sure other such wireless thermometers are any better after reading the reviews. It is a good thing to have an alarm when the temperature inside the freezer goes higher than a set level but finding such a device is a challenge. Wish the freezer had a built-in alarm. **** UPDATE **** Amazon, as always was true to their word to allow return of the defective product within the return period. More importantly, I failed to originally post the amount of ice build up around the freezer's lip where the "flat" cable passed under the rubber seal. Obviously air was flowing between the inside and outside of the freezer which caused ice to build up. It's amazing how much ice formed on the lip within 3 weeks. About 1/8" and likely to grow if given time. This is not a good thing to happen on a freezer which requires the cold air to stay away from outside air contact. I purchased a different probe via Amazon which does not require a cable to an outside box. The YoLink Smart Wireless Thermometer. The probe stays within the freezer without the need for an outside wire/cable. All truly wireless. I already have the YoLink hub for the water sensors thus adding this thermometer was easy and fit with the monitoring system. I was not aware YoLink made a freezer/refrigerator sensor. More importantly, the new probe works and for a fraction of this product's price.
