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.

Best Value: ThermoMaven P1

The ThermoMaven P1 (around £47.98) is the clever-value alternative to the winner. It is robust, precise and fully wireless, with a waterproof probe and a strong 152-metre Bluetooth range backed by Wi-Fi, so it does the important things the pricey models do for a fraction of the outlay. The app is not quite as polished as MEATER's, but the readings are reliable and the price is hard to argue with. For most home cooks dipping a toe in, it is the smart buy. Check the price on Amazon
Best for Big Cooks: MEATER Pro XL
If you regularly cook for a crowd, the MEATER Pro XL (around £329) is built for you. It brings the same excellent wireless MEATER system but with a set of four probes, so you can monitor several joints, steaks or birds at once and bring them all to temperature together — a genuine boon for a big barbecue or Christmas dinner. It is a premium outlay, but for dedicated grillers and large households it earns its keep. Check the price on Amazon

The ThermoPro TempSpike was a recommended budget wireless probe in the source test, but note that Amazon UK stocks ThermoPro's very similar "TempPro" range rather than the exact TempSpike model, so search carefully and compare the specifications if you want a ThermoPro. It remains a sensible budget-brand option alongside the ThermoMaven above.
How to Choose
Start with how much you cook. For the best all-round wireless thermometer with the finest app, the MEATER Pro is the one to buy. If you want almost all of that capability for far less, the ThermoMaven P1 is the value champion. And if you routinely cook several pieces of meat at once, the four-probe MEATER Pro XL is worth the premium. Whichever you choose, favour a fully wireless probe rated for real grill heat, check the range covers your kitchen and garden, and lean on the app's doneness presets until you trust your own judgement.
Verdict
The MEATER Pro is the smart grill thermometer to buy for most people at around £129: fully wireless, genuinely accurate and blessed with the best app in the test. The ThermoMaven P1 (around £47.98) delivers most of the magic for far less, while the four-probe MEATER Pro XL (around £329) is the answer for anyone who cooks for a crowd. Slide a probe into your next roast and you will never overcook a joint again.
