Weber iGrill 3

Built-in module for Weber gas grills

The iGrill 3 (Weber model number 7205) is a Bluetooth thermometer that does not stand next to the grill but clicks into its side shelf. Weber names the gas grills Spirit II, Genesis II and Genesis II LX as the devices it can be mounted on permanently. Up to four probes can be connected, and two meat probes come with the device. The readings appear in a smartphone app.

According to the manual illustrations and the Amazon photo, the module has no display; the app shows the temperatures. The 2017 Weber blog does say that the “display” flashes during pairing, but the illustrations show only a logo, a button with a light ring and a probe flap on the front. We read that as a reference to the light ring.

The iGrill 3 is not new. Weber announced it as a novelty on 22 February 2017 on the blog of its Canadian site, and the EU declaration of conformity in the manual is dated 2 July 2017. All shop and price details from Weber and Amazon in this text come from the check on 5 October 2026. In the Weber shop for Germany, the category “iGrill & Thermometer” shows five products, and the iGrill 3 is not one of them; on the British Weber site it is listed as an outlet item.

Weber names it only for the three series, and there only with the mounting plate on the side shelf. The GB site lists it as “iGrill 3 plate”, the US site as “iGrill 3 Ready”. The current gas grill page of Weber Germany lists no models with the suffix “II” and advertises integrated Weber Connect technology for Spirit, Genesis and Summit; whether and how that relates to the iGrill 3 or the iGrill app is not stated there. Our assessment: if you own a Weber without “II” in its name, ask Weber before buying instead of assuming compatibility.

Installation in the side shelf: six to eight steps

Plugging it in is not all there is to it. The German manual shows the installation on pages 4 to 17 as a picture sequence without text: six steps for the Spirit II, eight for the Genesis II and Genesis II LX, of which the sixth applies only to the LX. The wording of the first step comes from the US edition, a Weber document on a retailer’s server: “Remove cover plate. Some models may have screws.” In the German pictures, a screwdriver releases the cover plate of the side shelf, and the plate and two screws are discarded.

The three AA batteries do not go into the module but into a battery pack. Its holder sits on the grill frame on the Spirit II and under the side shelf on the Genesis II. You route the battery cable through the side shelf and plug it into the iGrill 3, which then clicks into place; according to the US edition, the module itself needs no screws. Finally, you secure the cable with the cable holder, which according to the US edition is stuck to the cleaned surface under the side shelf. On the Genesis II LX, the cable for the button lighting is added.

According to the German manual, the box contains the iGRILL 3, two meat temperature probes with red and yellow markings, two probe sleeves, a battery pack, a battery pack holder, a battery cable, three AA batteries and the cable holder. For a 3D guide, the manual refers to the free BILT app.

Probes, measuring range and heat limits

According to Weber, the probes measure from -30 to 300 °C. A single probe is 12.5 cm high, 1.3 cm wide and 6.6 cm deep, and the module measures 5.6 x 6.6 x 6.4 cm (height, width, depth, without box). Outside the measuring window, the app shows nothing according to the manual, and the connection to the probe drops.

Heat resistance is a separate matter. The GB product page states the meat probes are heat resistant up to 380 °C, and the manual requires that the cable is exposed neither to flames nor to temperatures above 380 °C; you should also not expose the probes to temperatures below -30 °C. Between 300 and 380 °C the probes therefore still survive but no longer display anything. That is how we read the two statements together; Weber words it differently.

Inside meat, the upper limit hardly matters, as target temperatures there are far below 300 °C. It matters for the ambient probe 7212, which is attached to the grill grate with a clamp and measures the ambient temperature at grate level. The lid thermometer, by contrast, normally sits at the top of the lid and registers the rising hot air, which is why the two values can differ; why is explained in our guide to grill thermometers. Whether your grill gets close to 300 °C at grate height depends on the model and the setting.

According to Weber, both additional probes, 7211 for meat and 7212 for ambient temperature, are made of stainless steel, and Weber describes the 7211 as suitable for all-day grilling. As a general rule for insertion probes (not a Weber specification), the tip belongs in the centre of the thickest part of the piece of meat.

Batteries, wireless and app

The iGrill 3 has no built-in rechargeable battery; it runs on three AA alkaline batteries in the battery pack. Weber states 250 hours of battery life and includes the batteries. If the figure means operating hours, one set of batteries is arithmetically enough for a good 20 cooks of twelve hours each or for 83 of three hours each.

Weber states 45 metres line of sight as the wireless range, and the Amazon catalogue gives the same figure for Bluetooth Smart. Bluetooth transmits in the 2.4 GHz band, which walls generally attenuate. With a house wall in between, the figure therefore no longer holds.

The app is called iGRILL app by WEBER in the manual. According to the Weber product page, it shows the temperatures, warns at the food’s cooking temperature and at grill temperature, saves favourite temperatures as presets and has timers. The 2017 Weber blog also describes preset alarms and time and temperature guidance for foods such as steak and chicken. Weber also advertises that you do not need to lift the lid and the cook is not interrupted. On Genesis II LX models, the button lighting can be switched on and off directly via the app, according to the English manual.

A smartphone is required, and not every one is supported: according to Weber, Huawei smartphones, among others, are excluded. The manual describes the setup like this: open the front flap on the module and insert the probes, download the app, switch on Bluetooth on the smartphone, then follow the pairing instructions in the app.

What is in the Amazon price of approx. €114.88?

A bundle, according to the title and the catalogue entry: the iGrill 3 (model 7205) plus the ambient probe 7212. Two meat probes and the batteries come with the iGrill 3, and a clamp for the grill grate comes with the 7212.

On Amazon the price is approx. €114.88 (catalogue check 5 October 2026). What the iGrill 3 alone costs there, we do not know. The outlet price on the British Weber site is £101.99 including VAT, previously £119.99.

Weber sells the meat temperature probe 7211 and the ambient temperature probe 7212 separately in the German shop for €19.99 each. Because Weber names four probes as the maximum and the bundle already contains three, by our calculation one socket remains free; another probe would bring the total price to €134.87 arithmetically. Running costs consist only of the batteries.

What else comes into question?

Three devices from our catalogue that a buyer without a suitable Weber weighs against the iGrill 3:

On the prices: they are guide values from our price data, for the iGrill 3 the Amazon check of 5 October 2026, for the others the state of the respective review file. On the score: an editorial assessment based on manufacturer information, without our own measurement.

At approx. €60, the Inkbird IBT-4XS costs €54.88 less than the Weber offer. According to Inkbird, it has a rotatable LED display on the device and a magnetic back for metal surfaces. The rechargeable battery has 1000 mAh, and Inkbird puts the range at 46 metres (150 feet), which makes it almost level with the iGrill 3’s 45 metres (both manufacturer figures). In our price data the MEATER 2 Plus stands at approx. €118, so €3.12 above the Weber offer. According to MEATER, the probe has five core sensors and one ambient sensor, and there is no cable under the lid.

The ThermoPro TempSpike Twin costs approx. €62.99, €51.89 less than the iGrill 3. The manufacturer states up to 150 metres in open terrain between the device and the smartphone and says that walls, metal lids and food reduce the range. According to the instructions, the distance from the probe to the booster can shrink to just 4 metres when the probe is in the meat and the metal cooker is closed; the booster should therefore be placed as close to the grill as possible.

For Weber owners without a mounting plate, Weber itself has the iGrill Mini in its range: suitable for all grills, but with only one probe. In the Weber shop it is listed at €63.74 (reduced from €74.99), but at the time of the check it showed “Notify me” instead of a basket button. More devices of this kind are shown in the best grill thermometers ranking, and all models in the grill thermometers category.

Cleaning and safety

The probes are cleaned before first use. They are not dishwasher safe, Weber prohibits chemicals and abrasive cleaning agents and requires wiping them with a damp towel or wet wipe. The probe cables and the connection area on the probe must not get wet, and the probes must never be immersed in water: they are not waterproof, and water can damage them.

For the module, the GB product page says: clean with a lint-free cloth and a non-abrasive cleaner, never immerse in liquid, the product is not waterproof.

The German manual requires you to read the safety instructions before first use and warns, among other things: the probes are very sharp. Without suitable protective gloves they can cause severe burns; the coloured probe markings are not heat insulated and must not be touched with bare hands while grilling, and Weber requires protective gloves to be worn at all times during use. You never leave the grill unattended while using the iGrill 3, and you also follow the grill’s instructions. Children and people with reduced physical, sensory or mental capabilities must not use the device.

On intended use: exclusively together with iGRILL-compatible Weber products, to measure and monitor the temperature of food being grilled. Other use can cause damage, and according to the manual neither the manufacturer nor the specialist retailer is liable for it. Batteries must never be thrown into an open fire and are disposed of according to local regulations; the old device does not go in household waste but to a collection point for electrical and electronic equipment.

What Weber does not state

We have not handled the iGrill 3. The sources of this text are Weber pages (product pages, manuals, declaration of conformity, blog), the Amazon catalogue, the manufacturer pages of the comparison devices and, for their prices and scores, our own review files; calculations and assessments are marked. The following details are missing from the Weber documents we have read (product page, manual, declaration of conformity):

• Weight of the module and probes
• Measuring accuracy in degrees, measuring speed, update interval of the values and alarm tones on the module other than the beep at switch-on
• Conditions for the 250 hours of battery life and the battery change procedure (all that is documented is that the batteries sit in the battery pack, not in the module)
• Housing material of the module (stainless steel is documented only for the probes)
• Length of the probe cable and position of the sensor in the probe
• IP rating
• Bluetooth version of the module and range through walls or floors
• Number of smartphones that can be paired at the same time
• Whether the module stores the temperature history if the connection drops
• Whether the four sockets may be assigned freely with meat and ambient probes
• Compatibility with the series without “II” and with Weber Connect technology
• Any discontinuation of the iGrill 3
• Country of manufacture and installation time
• Spare parts for the module, battery pack and holder

We have not checked whether the iGrill app is still maintained in 2026 and available in the app stores.

On the warranty: no warranty period is documented for the module, because the table in the warranty overview lists grill series and no iGrill 3. For its voluntary warranty against material and workmanship defects, Weber names up to fifteen years depending on the product or product part, provided assembly and operation follow the user manual; which period would apply to the module is not clear from this. Weber also refers to the two-year statutory warranty that applies in some EU countries. According to the manual, the importer is Weber-Stephen Products (EMEA) GmbH in Berlin; as the customer service contact for Germany it names Weber-Stephen Deutschland GmbH in Ingelheim.

When the iGrill 3 fits and for whom it does not

The first question decides it: do you own one of the three Weber gas grills with a mounting plate? If not, the iGrill 3 is ruled out. Then the choice is between the Inkbird (freestanding), the MEATER (no cable) and the TempSpike (longer wireless range); if a single probe is enough for you, Weber’s iGrill Mini, which according to Weber fits all grills, also comes into question.

If yes, what remains is a question of comfort: if you want to monitor several pieces at once, four sockets speak for the iGrill 3; in our assessment, a wireless probe without installation monitors a single large piece of meat just as well. If the grill is on the terrace and the smartphone next to it, the wireless range is enough. If you want to check from the sofa through the house wall, the TempSpike has more reserve according to the manufacturer (150 against 45 metres, under different conditions), though not unlimited. If you want to read the temperature at the grill without reaching for the phone, you need a device with its own display such as the Inkbird, and if you dislike changing batteries, a device with a rechargeable battery. And if you plan to switch to a newer Weber model soon, you would be buying a device for which Weber names only the series with “II”.

The iGrill 3 is not suitable for anyone who grills without a smartphone or uses the thermometer on changing grills. We would buy it only if the permanent mounting is worth something to you.
