If you’re a pitmaster or griller, you might have heard about Weber’s top thermometers: the iGrill mini, iGrill 2, and iGrill 3. While the model-mini has got no one confused, most grillers can’t seem to set the iGrill 2 and iGrill 3 apart. So, it might be important to know the difference between iGrill 2 Vs. iGrill 3, to pick the right one depending on your needs.

iGrill 2 Vs iGrill 3 Showdown

In this article, we’ll look at the iGrill 2 vs 3. Then we’ll have a peep at what recent customers have said about these iGrill thermometers. We’ll also offer a buying guide that might help you pick the better option between the two. 

To round off, we’ll provide answers to any question you might have about connecting or using either Weber thermometer.

Differences Between The iGrill 2 And iGrill 3
(iGrill 2 Vs 3)

The iGrill 2 and 3 look identical. Both products come with the same number of probes and have identical heat and water tolerance. They both measure similar Bluetooth ranges and work on the same Weber app. So, it was no surprise that many grillers got confused when the iGrill 3 was released a while after the iGrill 2 got into the market.

However, here are a couple of things to distinguish the two Weber Bluetooth thermometers from each other:


Grill Compatibility:

The grill you can use the smart Bluetooth thermometers on is perhaps the most significant difference in igrill 3 vs igrill 2.

As you might know, Weber produces not only thermometers but also grills. Some of the common ones are the Genesis II, Genesis II LX, and Spirit II series. Although you might want to use these grills alone, there are custom-made spots on them for iGrill 3 Bluetooth thermometers. If you don’t have any of these top grills from Weber, then you won’t be able to use the iGrill 3.

Alternatively, the iGrill 2 was not designed for any particular grill or to fit into any custom-made slot. So, you can use this Bluetooth thermometer with any smoker, grill, or oven.


Battery Life:

The second difference we think that’s worth noting about the two grills is their battery life.

The battery life of any thermometer is important if you want to get real-time temperature readings from it. Both the iGrill 2 and iGrill 3 come with replaceable AA batteries. However, while the iGrill 2 has two of these batteries inside the box, the iGrill 3 thermometer comes with 3 batteries.

As the iGrill 3 works on more batteries than the Weber iGrill 2, you would expect it to have longer battery life. Indeed, this is the case. While the iGrill 3 can last for 250 hours without requiring battery replacements, the batteries in the iGrill 2 work for only 200 hours before you have to change them.



Next on our iGrill 2 vs. iGrill 3 list is how to tell the two thermometers apart by looking at them. Indeed, we think this might be the first thing anyone would notice about the grills.

A display screen makes it a lot easier to check the doneness of your steak, chicken, or any other thing you might be smoking or grilling. However, not every device has this feature.

The iGrill 2 has an LED temperature screen. So, you can use the Bluetooth device as a standalone thermometer. This means that you might not have to get to your phone if you are close to your grill.

The iGrill 3 does not have an LED screen. The hole made for these thermometers in the Genesis II, Genesis II LX and the Spirit II are quite low. Indeed, they are almost at the same level as the control knobs. If these grills had an LED screen, then you might need to really bend to read off the temperatures of your slices of meat. This is one of the reasons we think the LED screen was ditched in the iGrill 3.


Weatherproof Capability:

Here’s another point in our Weber iGrill 2 vs 3 guide. The probes in both thermometers are not waterproof. However, we find it intriguing that only one of the two easy-to-mistake thermometers is weatherproof.

The iGrill 2 is not weatherproof. So, if you have your grill, smoker, or oven outside, you might want to bring it in during winter to use the iGrill 2. As with many other Bluetooth and electronic devices, excess moisture affects the iGrill 2, especially its LED screen.

On the other hand, the iGrill 3 is weatherproof. This means you should have no problem using the thermometer outdoors, especially as it doesn’t have an LED screen. However, you still have to be cautious when using it outside your home since the probes are not waterproof. If you want to protect the probe ports from damaging, then consider folding the cover after grilling.


Magnetic Fuel Level Sensor:

Remember how annoying it was when your propane tank got empty without you knowing? There’s hardly any way figure it out on most units, especially as these tanks are usually colored. Well, Weber has a solution for that in one of its grill thermometers.

The iGrill 3 has a magnetic fuel level sensor assembly. In some units like the Genesis II LX S-640, this sensor replaces the fuel indicator that is originally on the grill. And like before, you can monitor the propane fuel level from your Bluetooth-enabled device.

The iGrill 2 does not have this feature. So, there’s no way to know when you need a refill from the LED screen or your smartphone unless you walk to your grill.

Recent Customer Report On The
— Weber iGrill 2 Vs 3 —

iGrill 2:

iGrill 2

Recent customers reported that this Bluetooth thermometer worked with their grills, irrespective of the fuel type they used. Some customers were a bit confused that this thermometer also came with a CR2032 battery since there was no place to fit it. However, they quickly found that it was not required to operate the iGrill 2.

On the plus side, they were quite pleased with the battery life and the power-saving features it had. They reported that it would go to sleep when you move 30 feet away from the thermometer. However, it was said to last every second of its 200-hour life.

Also, several customers said that the bright red LED temperature numbers were readable and that the screen and port would definitely get ruined in the rain.

iGrill 3:

This thermometer has also received high praise from recent users. These users reviewed that they had little to no problems setting it up, connecting, or disconnecting the thermometer on their select grills. This, according to the users, is largely due to the intuitive app and explanatory user guide.

Most of them were pretty impressed with its battery life, especially as they claim anyone could forget to switch off the device.

The fact that you can use the iGrill 3 in any weather was one of the favorite things about this thermometer for recent customers. However, a large portion loved the fuel tank sensor feature more.
