What is the Weber iGrill 3?

The iGrill 3 is a two-probe food/meat thermometer. It has Bluetooth capability, app-built alarms, and recipes, and other indicators to monitor your cooking process. The probes measure the temperature of your meal, and the thermometer notifies you of the readings on your smartphone.

Its display includes:

  1. Bluetooth LED: This blinks blue when waiting to pair and illuminates blue when paired.
  2. Proximity sensor: This makes the thermometer sleep when your smart device is 30 feet away or wake when 5 feet near.

Key Features of Weber iGrill3 Thermometer


Heat-Resistant Probes

iGrill3 professional grade Probes

The iGrill 3 comes with premium, color-coded meat probes. Their wires are made of braided steel.

You can rotate the probes when they are in different food cuts and use them while the grill lid is closed. The two meat probes are heat-resistant up to 716 ̊F to withstand flare-ups and flames when grilling. 

In addition, the iGrill 3’s probes have double crimps. This, as well as their strong pull force, prevents the probes from detaching.


Fuel Level Detection

Most grills that are compatible with the iGrill 3 use liquid propane (LP) tanks. The Weber iGrill 3’s magnetic sensor indicates the remaining fuel in the grill’s LP tank. This is a pretty useful feature if you want to have complete visibility of your cooking process without going to your grill.

Users receive notifications on their smartphone (through the thermometer’s app) when their LP tank has a quarter fuel left. You must remove the fuel gauge before you install the thermometer.


Extensive Battery Life:

igrill 3 thermometer battery life

Weber includes three batteries that are designed to offer 250 hours of combined working time. Therefore, you won’t need to change them even if you grill or cook for eleven days nonstop.

The thermometer will automatically shut-off and save battery-life when:

  • No probe is installed, and the unit isn’t paired to a device for more than five minutes.
  • One probe is installed, but the unit isn’t paired to a smart device for more than eight hours.

As long as you install one of the probes and pair the thermometer to your smart device, the iGrill 3 will remain powered on.


IGrill Cool App:

The iGrill 3 is an app-connected thermometer. Virtually everything on the mobile-friendly software is customizable to meet your cooking needs. It allows you to:

  • Discover other users of the app and what they are cooking or grilling.
  • Get illustrations on temperature progression with time.
  • Set cooking time, alarms, notifications, or use the pre-set ones.

Our Thoughts and Test Results on Weber iGrill 3

The Weber iGrill 3 is a decent thermometer and a handy accessory for Weber-compatible grills. It’s arguably one of the most impressive Bluetooth thermometers with probes that read wide temperature food ranges. 

Our first impression of the thermometer was that it’s similar to other Weber products. However, we found new features in it like a magnetic fuel gauge and better battery-life that are absent in previous models. From our iGrill 3 review, our favorite thing about the unit is how well it mounts in the slot allocated for it. This prevents you from slapping it awkwardly on metal spots on your grill.

Of course, the iGrill 3 has quite some room for improvement. The probes that come in the box aren’t dishwasher safe or designed to measure your grill’s ambient temperature. You’ll need to get ambient probes separately if you want to measure your grill’s temperature with the unit.

Overall, we are convinced the iGrill 3 works as its manufacturer claims. With it, you would know when your food is ready or getting burnt but not when to flip it.

Let’s take a look at how the thermometer faired when tested:

1. Accuracy: The accuracy refers to the difference in temperature readings between the iGrill 3 and a standalone thermometer.

When it comes to Bluetooth thermometers, we’d say the Weber iGrill 3 is as accurate as it gets. You might only notice a difference of ±1°F. 

2. Battery Life: Weber claims that the iGrill 3 can last for 250 hours. From our iGrill 3 reviews and that of recent customers, this figure is on the money. Still, you could get more hours from the batteries by removing its probes when you’re done cooking.

3. Temperature range: According to Weber, the iGrill 3 reads temperatures between -22°F to 572° and shows’-d.c’ when placed in food outside this range.

We’d say that these claims are true.

The permitted temperature range should cover your frozen foods and blazing meals. However, we’d recommend you defrost your food before sticking a probe into it. Stabbing a probe in a frozen food can break it.

4. Convenience: There’s hardly any brain-racking aspect to deal with. The thermometer works with a button push, and anyone can find their way around the iGrill app without breaking a sweat. Therefore, we are convinced the thermometer is convenient to use.

5. Reading and response time: The response time refers to how long it takes to get your food’s temperature reading on your smart device. On the other hand, the reading time measures how long the probes need to be in your food to read the temperature.

While the iGrill 3 response time is 3 seconds, it takes the thermometer approximately 15 seconds to read your meal’s temperature.

  • Simple to operate the app and device
  • Provides accurate and timely readings
  • Allows long Bluetooth coverage over unobstructed paths
  • Long battery life
  • No LED display screen on the device.

Who is the iGrill 3 thermometer for?

Weber iGrill 3 thermometer is exclusively compatible with Weber Genesis II, Genesis II LX, and Spirit II gas grills series, which means if you don’t have those weber series, you’re not for iGrill 3.

It is best suited for adult grillers, having the above Weber gas grill series, who cook or grill one to four meals at a time and need to check the doneness of any of them.

However, you’re searching for a thermometer for your existing grill – which is not included above lists, check out the universal one – Weber iGrill 2.

You should also have a smartphone that’s compatible with the Weber iGrill App to use the thermometer. The compatible devices are:

  • iPhones (4S or later)
  • iPads (Third-generation or later)
  • iPad minis
  • iPod touches (sixth-generation or later)
  • Android gadgets (Android 6.0 or later and Bluetooth 4.0 or later) 


  • Huawei phones have connection issues with the iGrill unit.

Everything you need to know about using the Weber iGrill 3

1. Ease of use

As we stated earlier, the iGrill 3 is quite easy to use. All you need is to change the app’s configurations if you’ll rather not stick to the pre-set ones.

2. Ease of set up 

The iGrill 3 is also easy to set up. Grills that you can mount it on have a slot for the thermometer at the grill’s right side. The slot is covered by a plate, which you’ll need to remove before you can place the iGrill 3.

Next, remove the grill’s LED fuel gauge and install the magnet fuel sensor to your grill’s tank.

Then install the bracket underneath the right-side table.

Finally, download the Weber iGrill App and pair your smart device to it the thermometer. 

These steps, and everything you need to use the Bluetooth thermometer, are detailed in the user manual that comes with the device.

3. Compatibility with Weber and non-Weber grills

The iGrill 3 is an exclusive thermometer. It is designed for grilling enthusiasts and pitmasters who have any Spirit II or Genesis II grill. These are the only units that you can mount the thermometer on, and you should see the ‘iGrill 3 ready’ badge on these grills.

You can’t use the iGrill 3 on non-Weber grills, smokers, or ovens.

4. Cleaning and maintenance

Thanks to its fixed position on compatible grills, cleaning the iGrill 3 isn’t tough to work. A soft cloth and a non-abrasive cleaner will do the trick of making the thermometer look brand new.

However, its probes aren’t waterproof. Moisture shouldn’t enter the crimp and get to the probe’s wiring, or the probes could get damaged. Generally, Weber recommends that you fold up the probe cover after use and shield your grilling equipment (including the iGrill 3) with a grill cover.

Other cleaning and maintenance tips you should keep in mind include:

  • Clean the probes with a sanitary wipe or damp towel.
  • Avoid the probe’s wiring or the spot where the wiring meets the probes when cleaning.
  • Don’t use chemical cleaners on the thermometer.
  • Don’t mix new and old batteries. Also, ensure you use only AA batteries.

5. Warranty details

This unit is made in China and is backed by a three-year warranty. Any modification you make to the product, like making it usable on non-Weber grills, nulls and voids the warranty.

Final words

The iGrill 3 is undoubtedly an impressive Bluetooth thermometer. It saves you from wondering about one less thing while cooking and allows you to multi-task up to the moment when your meal is ready.

In our iGrill 3 review, we’ve looked at all the talking points of Weber’s cool thermometer: the iGrill 3. We can see why many users think it’s better than other Weber thermometers (iGrill Mini, iGrill2) and worth considering if you have a compatible grill for it.

Weber could improve a few sections like the thermometer’s lack of display screen and proximity issue. However, there’s no question that the iGrill 3 is a solid unit. 

Wouldn’t you rather use the Weber iGrill 3 instead of guessing the doneness of your meal?

Is the thermometer weatherproof?

Yes, it is. You can leave the thermometer permanently on your grill. However, be sure to keep your wrap the probes and then place them in their case once you’re done using them to check your food’s doneness.

The probes don’t attach to the grill.

Can I save the temperature data on the app?

No. There’s no option to save charts or any other temperature data on the app. However, you can export the graphs you need to your email address as a CSV file.

Is there a way to calibrate the probes that come in the box?

No. There’s no option to calibrate the probes. As long as you use them correctly, you shouldn’t need to modify them. However, you can reach out to Weber if you notice your probes give false readings.

Do the probes, wires, or wraps get in the way of cooking?

The probes and wires could litter around your food while cooking. If you route the wires and ensure the slack is outside the grill, you wouldn’t have to worry about them. 

The colored rubber indicators aren’t heat resistant. These plastic indicators should always be left hanging outside your grill.

Does the Bluetooth thermometer interfere with other smart device functions?

No, the iGrill 3 won’t interfere with other things you want to do with your smart device. Also, each thermometer has a unique identification. You can only pair one smart device with the thermometer at a time.
