Bluetooth vs Wi-Fi meat thermometer

Updated: 22 October 2026

The kettle is at the back of the garden, and the app has already frozen once. Bluetooth vs Wi-Fi meat thermometer is the decision about how far you are allowed to walk, not which brand has the longest number in the title. Bluetooth talks locally. Wi-Fi, on these hubs, is a second hop through a base, and that hop is often 2.4 GHz only. Sub-1G sits between the probe and the base and is not Wi-Fi. The [Bluetooth grill thermometer comparison](/hub/grill-accessories/bluetooth-grill-thermometer) lists which row uses which radio. The format choice, before the radio, is the [buying guide](/hub/grill-accessories/bluetooth-grill-thermometer/sub/bluetooth-grill-thermometer-buying-guide).

What each radio actually does

Bluetooth in this set is a local link. On a cabled box it runs from the receiver to the phone, while the probes themselves are on wires. The TP904, INKBIRD, Meatmeet, LYMIN and SENSTREE are the Bluetooth-only rows. You do not need a home network. If you go upstairs, it often drops. Wi-Fi is the relay: a base near the cooker joins your router. Chef iQ Sense, the G1, the P1, BFOUR, the ProTemp S1 and the P2 all add Wi-Fi. The base still has to sit by the grill. When the router is down, the remote hop is down. Sub-1G is easy to misread as better Wi-Fi. On the X2 the attribute line is Sub-1G and the bullets say no app is required. On the G1 the bullets add Sub-1G between probe and base, while the attribute still says Wi-Fi. It is not a promise that your phone works from a train.

Why the metre number shrinks

The titles are written in open air. TP904 says 135 m. Fifty United Kingdom reviews say the signal is lost at the end of a garden and inside the house. X2 says 915 m. One United Kingdom review lost the connection at 30 m through walls. Those numbers can be true in a field and still fail on a patio with a closed lid. A kettle, a kamado and an oven are metal boxes. INKBIRD’s manual wants the base outside the cooker and within about 10 metres, closer if metal is in the way.

The 2.4 GHz limit

Several Wi-Fi hubs in this capture join 2.4 GHz and refuse a 5 GHz-only network. A United Kingdom reviewer returned the ProTemp S1 because the Wi-Fi was 2.4 GHz only. The P2 draws the same comment, and a separate buyer could not hold a link to the base on two units. BFOUR’s bullets state 2.4 GHz as the compatible mode. A 5 GHz-only garden node will not join the hub. You buy the Wi-Fi hop when you leave the patio, and you still leave the base next to the cooker. Wi-Fi spends the battery faster: the ProTemp bullet claims up to 40 hours on Wi-Fi, or 300 hours on Bluetooth only. If you will not run 2.4 GHz, choose a Bluetooth-only row or the X2.

Which to buy for how you cook

Stay near the cooker and Bluetooth matches the walk. The TP904 at about £26.99 is the cheap version, with cables and a range United Kingdom reviews already cut down. Leave the garden for the kitchen and a Wi-Fi base is the row that tries to follow you. The G1 at about £69.99 has 3,012 reviews and a screen that still works if you ignore the app. The P2 at about £109.99 is the two-probe Wi-Fi row, with breakage notes in the United Kingdom file. The ProTemp S1 is Wi-Fi for pit air, not for the meat. If you can see the kettle, ignore the Wi-Fi premium. If you need the alarm in the house, buy Wi-Fi and a 2.4 GHz network.

Common questions

Will Bluetooth reach from the garden into the kitchen?
Sometimes, and you should not plan on it. TP904 reviews lose the signal inside the house and at the end of the garden, against a 135 m claim. If the kitchen is where you want the alarm, use a Wi-Fi base next to the cooker.
Does Wi-Fi mean I can check from anywhere?
Only while the base is online. The base still sits by the grill. If the broadband is down, the remote view is down. A local screen, such as the G1’s base, is the reading you still have in the garden.
Why does my hub refuse a 5 GHz network?
Because several of these listings are 2.4 GHz only. A United Kingdom buyer returned the ProTemp S1 for that, and a P2 review says the same. A 5 GHz-only mesh node will not join the hub.
Is Sub-1G the same as Wi-Fi?
No. Sub-1G on the X2, and in the G1’s bullets, is the link between the probe and the base. Wi-Fi is how a base joins your router. A 915 m claim already failed at 30 m through walls in one United Kingdom review.
Do I still need the base next to the cooker if I have Wi-Fi?
Yes. Wi-Fi starts at the base. The probe still has to reach that base through the lid. Put the base on a side table by the kettle, not in the house.
Which captured models are Bluetooth only?
TP904, INKBIRD INT-11I-B, Meatmeet S Pro, LYMIN DT-133 and the SENSTREE receiver. The X2 is Sub-1G, not Bluetooth. Chef iQ Sense, G1, P1, BFOUR, ProTemp S1 and P2 add Wi-Fi.
Why did the range die when the oven door shut?
The door is a metal shield. Bluetooth at 2.4 GHz drops through it. Open-air figures such as 152 m, 305 m or 610 m were not measured with that door closed. Move the base closer before you change the target.
