A smart grill thermometer takes the guesswork out of cooking meat. You push a slim wireless probe into the joint, steak or bird, and it beams the internal and ambient temperature straight to your phone — so you can pull everything off at the perfect moment without lifting the lid, piercing it repeatedly or hovering over the barbecue. An extensive test of smart grill thermometers sorted the best, and these are the top picks, checked against current UK prices.
What to Look For
Wireless design and range. The best modern probes are completely wireless — no trailing cable from the meat to a base unit — so you can shut the lid or the oven door on them. Check the range: a good one holds a Bluetooth link out to around 152 metres, and models with Wi-Fi can extend that across the whole house and garden so you can nip inside while the brisket finishes.
Sensors and accuracy. Accuracy is everything. The best probes pack several sensor points into the tip, reading the true core temperature of the meat as well as the ambient heat of the grill at the same time, so nothing is over or undercooked. A precise, quick-reacting probe is what separates a great thermometer from a gimmick.
Heat resistance. The probe has to survive the grill. Look for one rated for high ambient cooking heat — typically up to around 300°C — with the tip able to withstand brief exposure up to 550°C for searing. A probe that cannot take the heat will fail exactly when you need it.
App and presets. Because the readout lives on your phone, the app makes or breaks the experience. The best offer preset target temperatures for every meat and doneness — from a rare 59°C to a well-done 66°C and beyond — with clear alerts, cook timers and guided steps. The winner here stood out for having the best app in the test.
Number of probes and battery. One probe is plenty for a single roast, but if you cook for a crowd or run a big barbecue, a set of up to four probes lets you monitor several pieces at once. All of these charge in a small block or case that also stores them, giving many hours of cooking between charges, and a fully waterproof probe is easy to clean.
The Winner: MEATER Pro
The MEATER Pro (around £129) is the best smart grill thermometer for most people. This is the fully wireless probe formerly sold as the Meater 2 Plus, now refined: it reads with multiple sensor points in the tip for genuinely precise core and ambient temperatures, and it is paired with the best app in the test, packed with guided cooks and presets. The probe shrugs off grill heat, charges in its neat wooden block and simply works, cook after cook. As an accurate, beautifully judged wireless thermometer, it leads the field.
