The Weber iGrill 3 is the hardest thermometer in my wireless thermometer guide to recommend on price, and the easiest to recommend to a specific person: someone who owns a Weber Genesis II, Genesis II LX or Spirit II with an “iGrill 3 Ready” plate on the side table.
It is built to dock into those grills. If you have one, it is a tidy, well-rated, long-lived bit of kit at $109.99. If you do not, you are paying a hundred and ten dollars for two probes and Bluetooth, when $42.98 buys four probes and more range elsewhere.

This is a grill accessory before it is a thermometer
Most wireless thermometers are sold to anyone with an oven or a smoker. The iGrill 3 is sold to Weber owners: it mounts into a moulded slot on the side table of specific Genesis II and Spirit II models, and that integration is most of what the price is buying.
It works as an ordinary Bluetooth thermometer on any grill or oven — nothing stops you using it with a kettle barbecue or in a kitchen. But then you are buying the mounting and the Weber badge and not using either, which is a poor way to spend a hundred and ten dollars.
Judge it on that basis and the verdict is straightforward. As a Weber accessory it is good. As a general-purpose thermometer bought on merit, it is beaten comfortably on probe count, on range and on price.
Who It’s For
- Owners of a Genesis II, Genesis II LX or Spirit II with the iGrill 3 Ready plate
- Anyone who wants the longest battery life here — Weber states 250 hours
- Buyers who want a mainstream brand with a service path rather than a marketplace name
- Cooks happy with two probes and Bluetooth range
Who Should Look Elsewhere
- Anyone without a compatible Weber grill — the main reason to buy it does not apply
- Anyone who wants four probes; this ships two, and four costs extra
- Cooks who wash their probes — Weber states the unit is not waterproof and must not be submerged
- Value buyers: the four-probe TempPro is $42.98 and the precision-focused Typhur is a different tool entirely
Performance
Two probes, four-probe capacity
You get two colour-coded probes in the box and the unit will take four, so the capacity headline is real but you are buying the extra two separately. That is a meaningful difference from the TempPro, which ships four for a third of the price.
Two probes covers a joint plus the chamber, or two cuts with no ambient reading. For most gas-grill cooking that is adequate; for a long smoke where you want three meats and the pit, it is not.
250 hours of battery, and why that is the real feature
A stated 250 hours is far beyond anything else in this guide, and it is the specification I would actually buy it for. A thermometer that lives in a drawer between uses and is dead when you need it is a common and infuriating failure, and this one avoids it.
It is Bluetooth rather than WiFi, so the monitoring range is the house and garden rather than anywhere with internet. The difference is set out in Bluetooth vs WiFi meat thermometers.
The thing Weber tells you not to do
Weber’s own cleaning instruction is explicit: clean with a lint-free cloth and non-abrasive cleanser, and never submerge it, because the product is not waterproof.
On a device that lives outdoors next to a grill and goes into raw meat, that is a genuine limitation rather than boilerplate. The Typhur Sync Gold rates its probes IPX8 and 932℉; this one is plastic and must be wiped. It is the single specification that most separates the two.
Design and Build
A plastic body with colour-coded probes, designed to sit in the side-table slot of a compatible Weber. On those grills it looks like part of the machine rather than an accessory bolted on, which is the point.
App support is broad — iOS 11.1 or later, Android 6.0 or later with Bluetooth 4.0 — so old phones are unlikely to be a problem. That is worth something on a product that has been on sale for years.
Value
At $109.99 this is the middle price in the guide and the weakest specification for the money. Two probes and Bluetooth for $109.99 sits against four probes and 650ft of Bluetooth for $42.98 on the TempPro.
The value only works one way: if you own the right Weber, the docking and the brand support are worth something real, and the 250-hour battery is the best here. Outside that, there is no argument for it that survives looking at the price of the alternatives.
Durability
Across 5,551 ratings the distribution runs 76% five-star, 14% four, 6% three, 1% two and 3% one-star. That 3% one-star share is the lowest of the three thermometers I have reviewed, on a healthy sample.
That is a genuinely good record and the strongest thing about the product after the battery. Weber has been making this model for years, which is why the sample is large and why app compatibility reaches back to old phones. The reservation is not reliability — it is that you are paying a premium for integration most buyers will not use.
Alternatives to Consider
- TempPro TempSync 650ft — $42.98. Four probes, 650ft, 10,331 ratings. The better buy unless you own a compatible Weber.
- Typhur Sync Gold — $152.99. WiFi, a stated ±0.5℉ accuracy and IPX8 probes rated to 932℉. The pick if precision is the point.

Verdict
The Weber iGrill 3 is a good product with a narrow audience. The 250-hour battery is the best in the guide, the 3% one-star share across 5,551 ratings is the cleanest record here, and on a compatible Genesis II or Spirit II it docks into the grill and looks like it belongs.
Everywhere else it loses on the numbers. Two probes against four, Bluetooth against WiFi, no water rating at all, and $109.99 against $42.98. Buy it because you own the grill it was made for. Do not buy it as a general-purpose thermometer, because two cheaper and one dearer option all beat it at something that matters more.
How This Review Was Put Together
Plainly: this is research-based, not a hands-on test. I have not owned or used this thermometer, and nothing here should be read as a report from my own kitchen.
What it rests on: the published specification — probe count and capacity, wireless standard, battery life, grill compatibility and water rating — read against the other thermometers in my wireless meat thermometer guide; plus the shape of the rating distribution across 5,551 Amazon ratings rather than the 4.5 average it produces.
What I could not establish: accuracy tolerance and response time, neither of which Weber publishes; whether the stated 250-hour battery holds after a few years of charge cycles; and real Bluetooth range, which Weber does not specify at all.
Price and stock were read from Amazon’s US marketplace on 7 September 2026 and will move.
Frequently Asked Questions
Does the Weber iGrill 3 only work with Weber grills?
No. It is a Bluetooth thermometer and works on any grill, smoker or oven. What is Weber-specific is the mounting: it is designed to dock into the side table of Genesis II, Genesis II LX and Spirit II grills fitted with an iGrill 3 Ready plate. Without one of those you are paying for integration you cannot use.
How many probes come with the iGrill 3?
Two, though the unit takes four. Extra probes are bought separately. For comparison, the TempPro TempSync ships four probes at $42.98.
Is the Weber iGrill 3 waterproof?
No. Weber states it must never be submerged and should be cleaned with a lint-free cloth and non-abrasive cleanser. That is a real limitation on a device used outdoors and around raw meat.
How long does the battery last?
Weber states 250 hours, which is by a wide margin the longest in my guide and the single best reason to own one. How well that holds up over years of charge cycles is not something the specification tells you.
Is the iGrill 3 worth $109.99?
Only if you own a compatible Weber grill. On specification alone it is beaten by the $42.98 four-probe TempPro on probes and range, and by the Typhur on accuracy and build. The docking, the brand support and the battery are what you are paying for.
Does it work with Android?
Yes, Android 6.0 or later with Bluetooth 4.0, and iOS 11.1 or later. The compatibility reaches back a long way, which is useful on a product that has been sold for several years.
