You’ll be counting losses…and you’ll feel the pain!

But you don’t have to deal with all this mess, thanks to the invention of the best freezer alarm—a device that’ll warn you when your freezer temperature exceeded the pre-set levels.

This will enable you to make the necessary adjustments on time to ensure your frozen food remain fresh and safe for your family consumption.

In the following post, we’ll shed more light on how helpful this device can turn out to be to homeowners. We’ll also give you our ultimate list of the 10 top-rated alarm freezers on the market today.

Why You Need a Wifi Freezer Alarm?

A wifi freezer alarm will send you alerts over the internet—anywhere, anytime—whenever your freezer temperatures go beyond the pre-set levels.

As we’ve just stated above, this will help you take the necessary action to prevent your frozen food from getting thawed and spoilt.

With that in mind, you might be asking yourself if you really need to invest in a wifi freezer alarm.

We think you should!

Here’s why:

The wifi freezer alarm will remotely alert you when your freezer temperature exceeds the maximum or minimum temperature range as set by you.

This means you don’t have to be near your freezer all the time in order to monitor its temperatures (how convenient!)

And once you have this device installed in your freezer, you can start receiving alerts from any location as long as there’s an internet connection.

By sending you the alerts on time, you’ll be able to act right on time to prevent accidental thawing and spoilage of the foods, medication, or any other temperature sensitive contents in your freezer.

Think about all the money you have spent on the goodies inside your freezer right now. If the temperatures inside fluctuate without your knowledge, you’ll be counting huge losses. You’ll be forced to replace these foods, which means spending more money!

It’s a well-known fact spoilt foods can result in food borne illnesses. The last thing you want is all your family members to get sick after consuming the spoilt food.

The same case applies to medication. If your freezer temperature exceeds the optimum values, they’ll get damaged, and might become poisonous if administered to humans.

And oh! A freezer alarm doesn’t cost you an arm and a leg. Despite the crucial role they play in protecting your frozen food and saving you huge sums of money, these devices are incredibly affordable.

How To Get The Right Product For You?

When it comes to selecting the best freezer alarm, there are certain aspects you should keep in mind to ensure you get the most suitable model for your unique needs.

These factors include:

Alarm system

The first thing you should look for in a freezer alarm is how it sends you alerts. The best model should be able to send you audio as well as visual alerts. This will make it easier for you to receive the alerts on time and make the necessary adjustments to keep your frozen food safe.

For the audio part, we suggest that you look for a model that beeps until you manually put it off (though this is not necessary). The best thing about such an alarm system is that it’ll not go off before you actually get the warning.

As long as the audio alarm rings loudly, you won’t have any problems receiving the alerts on time.

Types of readings

You should also pay attention to the kinds of readings offered by the freezer alarm you plant to buy.

As you’ve seen in our top-rated products, the best freezer alarms are capable of monitoring indoor as well as outdoor temperatures.

They’re also able to keep a memory of the maximum and minimum temperature recordings. These particular readings are crucial in helping you understand the temperature trends of any given place.


How easy is the main unit (or console) to use? The best freezer alarm for your home should come with an intuitive, easy to operate unit.

Each key should be clearly labeled so that even a 3-year old kid or older family member knows its function. Units with fewer operations buttons/keys are usually easier to operate.

While still on it, check the display panel of the unit. It should not only be bigger but should also display larger digits to help you easily take the temperature readings.

Ease of installation

You want to ensure the device you invest in does not give you headaches when it comes to installing it, right?

Well, look for a model that’s super-easy and fast to set up.

Most of the top-rated models you’ll find on the market actually offer you up to 3 mounting options—like the magnetic back, tabletop, or wall hanging—to enable you to choose the most convenient option for you.


Don’t forget to look if the device manufacturer offers you any warranty or guarantee.

You might not know this, but a warranty acts as a way of the manufacturer assuring you of the quality of their product.

If you get a product with a warranty, you can easily send it back to the owner if it doesn’t meet your needs or even ask for a replacement if the current one fails.

The longer the warranty period, the better the deal!

Additional factors:

  • Transmission range: a freezer alarm with more extended transmission range makes it possible for you to monitor your freezer temperatures when you’re far from it.
  • Number of sensors: models that come with more than one remote sensor enable you to monitor several areas simultaneously.
  • Update frequency: a freezer alarm that frequently updates its readings, say after 30-90 seconds, is more reliable in monitoring your freezer temperatures
  • Power source: ensure that the batteries required to run the device are readily available for hassle-free replacement when the need arises.
  • Low battery indicator: this feature is crucial as it helps you replace the batteries on time to ensure continued unit functionality.

Final Verdict

Monitoring the temperature of your freezer is crucial to ensure your frozen food, medication, and other frozen assets do not get damaged.

If your freezer temperature rises or fall below your preset range, the freezer alarm will alert you immediately. And this will help you take the right action on time to prevent huge damages, losses, and frustrations.
