Overview
The iGrill 3 is Weber's app-connected meat thermometer that pairs with select gas grills through a dedicated mounting plate. It tracks up to four probes at once and reports temperature to a phone or tablet over Bluetooth, replacing a manual check under the lid.
- Four-probe capacity, two probes included
- Mounts into the Genesis II / Genesis II LX / Spirit II side table
- 250-hour battery life
- IOS and Android app monitoring
Who it's for
Suits owners of a compatible Weber gas grill who cook enough to want a probe left in the meat without stepping outside to check it. Less useful for anyone without one of the three named grill families, since the mounting plate is grill-specific.
What buyers say
From Amazon customer reviews.
Reviewers who own a compatible grill call it accurate and satisfying to use, with the temperature graphs helping predict doneness. The recurring complaint is Bluetooth reliability: one owner traced dropped connections to hot ambient weather above roughly 87 degrees Fahrenheit, and another said reconnecting sometimes takes a manual power cycle. A couple of reviewers also noted some probes read less accurately than others.
Strengths and trade-offs
Drawn from this product's published specifications.
- Tracks up to four cuts of meat at once
- Notifies your phone when target temperature is hit
- Long claimed battery life at 250 hours
- Accepts probes from older iGrill Mini units
- Bluetooth can drop in hot weather or out of range
- Only fits three named Weber grill families
- App interface takes some getting used to
- Reconnecting sometimes needs a manual power cycle
Performance notes
The unit runs on two included probes for a claimed 250 hours and reports through the free Weber app rather than a built-in screen. Bluetooth range is the main variable: several owners found the connection dropped and needed a manual reconnect once they moved out of range of their phone, or once outdoor temperatures rose, though one report was resolved entirely by a warranty replacement unit.
