iGrill 3 Review

Essentially, they remove the guesswork of trying to cook your food at the right temperature.

Some of the most popular smart thermometers have been Weber’s iGrill series, which is now in its third incarnation.

iGrill 3

The iGrill 3 is a high-tech thermometer and Bluetooth enabled device, which delivers alerts and data directly to the smartphones of users.

The probes measure the temperature of your food, and the thermometer then notifies you of the readings on your smartphone. Super easy and super effective. 

Technical Specifications:

  • Dimension: 2.2 x 2.6 x .5”
  • Individual Probe Dimension: 5.0 x 0.5 x 2.6” 
  • Weight: 1.35 pounds
  • Batteries: 3 x AA

Included with the iGrill 3:

  • One iGrill 3 (obviously)! 
  • 3 x AA batteries
  • 1 x battery pack assembly
  • 2 x probes and probe wraps
  • 2 x probe indicators (these will be red and yellow) 
  • One magnetic fuel level sensor
  • One installation guide

Note, if you’re after other accessories such as colour wraps, these must be purchased separately. 


There’s nothing worse than purchasing a gadget you’re really excited about using only to find it takes hours to properly set up. Luckily, the iGrill 3 is quick and easy to set up, just as long as you have a grill from Weber’s Genesis series. 

If you do, you’ll find a slot for the thermometer on the right side of the grill. The slot should be covered by a plate, so remove this, as well as the fuel gauge.

In its place add the magnet and feed in the bracket – this should go through the underside of your grill and onto the surface of the grill.

Then you can take the 3 AA batteries provided with the product and put them into the iGrill’s battery box, before mounting this to the grill and plugging it in. Finally, place the iGrill 3 on the bracket and then tightly secure all the wires.

All that’s left to do then is to download the Weber iGrill app and pair your smart device to the thermometer. 


As mentioned above, the iGrill 3 is an exclusive thermometer, and is therefore only designed for grilling enthusiasts with the Genesis II or Spirit II grill.

These two units are the only ones you can mount the thermometer on and should be labelled with a “iGrill 3 ready” symbol. Unfortunately, you can’t use the iGrill 3 on any non-Weber grills, smokers or ovens. 


Performance-wise, the iGrill 3 is excellent. It provides alerts for maximum and minimum temperature which helps to easily adjust the temperature of your grill.

In addition to providing detailed information about the cooking process, the iGrill connects easily to the Weber app, allowing you to share the food you cooked, your cooking temperature, and your various activities with friends and family on social media. 

As you improve your cooking skills and become more confident with the iGrill 3, you can customize your cooking or look to select a temperature that’s easy for different meat options.

Also, if your grill model uses propane, there’s a fuel level detection feature which is handy for knowing how much fuel you’ve got left in the tank. This reduces the risk of getting caught unawares whilst cooking. 

Another quality which emphasizes the high overall performance of the iGrill 3 is just how convenient it is to use.

There’s nothing complex or daunting that’ll stress you out, the thermometer works with a simple button push. The iGrill app is equally straightforward to use. 


The iGrill 3 comes equipped with high-quality probes that are heat-resistant up to 716℉. This helps them to withstand flare-ups and large flames when grilling.

The probes can be rotated in different food cuts and used whilst the lid of the grill is closed. They’re also color-coded (red and yellow) to help differentiate between the different probes when cooking.

The iGrill 3 comes with two probes, but the device has four ports so you can add an extra two probes if you want. 

Another key feature of the iGrill 3 is its extensive battery life. The three batteries have a combined working time of up to 200 hours.

Therefore, even if you’re looking to grill or cook for 8 days straight, you wouldn’t need to change the batteries. The long-lasting battery life is also aided by an auto shut-off feature.

This effectively turns off the device to save battery when either no probe is installed and the unit isn’t paired for longer than 5 minutes with a device, or when only one probe is installed, but the unit isn’t paired to a smart device for longer than 8 hours.

So long as one of the probes is installed and the thermometer is paired to a smart device, the iGrill 3 will remain switched on. 

In terms of the device’s wireless range, it comes with a heavy duty Bluetooth function that’ll enable you to control your grilling temperatures from distances up to 150 feet away.

So, if you want to go and lounge by the pool whilst your food continues to sizzle away, or go inside and pour some drinks for your guests, the efficient Bluetooth capacity of the iGrill 3 will enable you to do so without stress. 

Cleaning and Maintenance

The iGrill 3 has a fixed position on all compatible grills. Therefore, it’s relatively simple to clean and maintain. A soft cloth and a non-abrasive cleaner will do the job of making your thermometer look brand new after cleaning. 

It’s worth noting however, that the probes of the iGrill 3 aren’t waterproof. Due to this, it’s important to avoid moisture from coming into contact with the probe’s wiring and damaging them.

It’s recommended by Weber that you fold the probe cover up after use and shield your grilling equipment with a grill cover. This includes protecting the iGrill 3. 

In terms of other cleaning and maintenance tips to keep in mind, you should clean the probes with a sanitary wipe or damp towel – just make sure you avoid cleaning the probe’s wiring or the area where the wiring meets the probes.

It’s also best to avoid using chemical cleaners on the thermometer, as well as not mixing old and new batteries. In order for the iGrill 3 to work effectively and safely, only use AA batteries. 

Frequently Asked Questions

How does a Bluetooth barbecue thermometer work? 

It all starts with the probes that are attached to the inside of the grill. These send information about the temperature into the transmitter, which then sends the temperature information onto a receiver (smartphone).

If you are positioned near to the grill, you’ll be able to see the temperature on a readout display. 

What’s the difference between the iGrill 3 and the iGrill 2? 

The main difference is compatibility. While the iGrill 3 is specifically designed for Weber’s Genesis and Spirit series of grills, the iGrill 2 is a stand-alone model that can be used for any grill, including most non-Weber grills.

The iGrill 3 has a slightly longer-lasting battery life and is permanently mounted to the table side, whereas the iGrill 2 is mounted magnetically. 

How do I connect my iGrill 3? 

This is a simple and straightforward process. Firstly, go onto your smartphone’s app store and download the iGrill app by Weber.

Then switch on your iGrill 3 and turn on Bluetooth. Once it’s downloaded, open the app on your phone and select your device from the menu (should be aptly named “iGrill 3”). Very simple! 

Will being connected to the Bluetooth thermometer interfere with other smart device functions? 

No, the iGrill 3, once connected, won’t interfere with anything else you want to do with your smartphone. Each thermometer has its own specific identification, so can only be paired with one smart device at a time. 

Do the probes and wires get in the way of cooking? 

The probes and wires do sometimes litter around your food whilst it’s cooking. But if you route the wires and make sure that the slack is outside the grill, you shouldn’t have to worry too much about them. 

Can I calibrate the probes that come in the product box?

No, there isn’t any option to calibrate these probes. However, if you use the probes correctly, there shouldn’t be any need to modify them.

If you believe that they’re giving you false readings, it’s best to reach out to Weber and let them know about the problem.
