Wireless or wired smoker thermometer

Updated: 23 October 2026

You do not know whether you would rather fight a cable or a battery. A wireless or wired smoker thermometer fails in different ways, and the useful choice is the failure you can live with on this cooker. A cable can be pinched or melted. A spike can arrive flat or stop pairing after a few months. Price bands stay on the [smoking thermometer buying guide](/hub/grill-accessories/smoking-thermometer/sub/smoking-thermometer-buying-guide).

Three different things called wireless

The word on the box is not the wire in the lid. A wireless barbecue thermometer can still mean cabled probes talking to a receiver. In this capture there are three shapes. The first is a cable to a box, and Bluetooth only from that box to the phone. The TP904 at £26.99 and the SENSTREE at £37.99 are this shape. Two United Kingdom SENSTREE reviews expected wireless probes and could not close an oven door. The second is the Thermapen Smoke at £108: cables to a transmitter outside the cooker, then a radio to a receiver. The probes are still wired, and this listing does not name Wi-Fi. The third is a leave-in spike with no cable: TempSpike, P1, G1, X2, G2 and the Inkbird. The probe still has a battery.

When the cable is the better tool

A cable has no probe battery to forget. The TP17 at £18.94 and the TP904 run from cells in the base, and the Smoke’s manufacturer page states about 1,800 hours on its AA cells. That fits if you stay near the cooker and would rather replace a lead than find a flat spike. The air probe can sit at the grate, away from the meat. A single spike’s ambient sensor cannot. The lead has to pass the lid. One United Kingdom TP904 review shut the lid on the cables without damage on that cook. Keep the lead off the coals and the plastic base off the cooker. A TP17 review melted the case on a hot barbecue. The TP904 bullet says 135 m, and several United Kingdom reviews lose Bluetooth before the end of the garden.

When the spike is the better tool

Buy a wire-free probe when you will not compromise the lid seal, or when a rotisserie or a tight gasket makes a cable a nuisance. A closed metal or ceramic lid weakens 2.4 GHz Bluetooth, so the booster has to sit close. An open-field range is not the range through the dome. Several United Kingdom TempSpike reviews say the probe stopped pairing after months. One P1 probe stopped charging after about six months. The Inkbird file includes a dropout at about 4 m. Charge the spike the night before. The X2 claims 915 m and one United Kingdom review lost it at 30 m through walls. The G2’s Wi-Fi can leave the house when the X2 cannot, and the base still has to hear the probe.

What to buy from this set

Stay with a cable if you will be in the garden and you want no probe battery. The TP904 at £26.99 is the best value dual: a screen, two probes, and a short real Bluetooth range. The Smoke at £108 is the cable plus a receiver, if you accept a 300°C ceiling. Buy a spike if the gasket or the rotisserie is the constraint. The X2 at £79.99 is two probes and no app, with that 30 m through-walls review. The G2 at £109.99 is the top pick when you want two wire-free probes, a screen and Wi-Fi. Skip the TempSpike if you need pairing past the first months. Skip the SENSTREE if you thought Bluetooth meant no wires. Where the tip and the grate clip go is the how to use a smoker thermometer page. A cook that has to survive the night is the low and slow page.

Common questions

Will a cable ruin a kamado gasket?
It can wear a gasket if it is pinched in the same spot every cook. A United Kingdom TP904 review closed the lid on the cables without damage that time. If you will not accept any lead in the seal, buy a spike.
Does wireless mean there is no wire at all?
Not on every listing. On the SENSTREE and the TP904, Bluetooth is the phone link and the probes are cabled. On the G2, X2, G1, P1, TempSpike and Inkbird the probes themselves have no wire.
Why does Bluetooth die when the lid shuts?
A closed metal or ceramic cooker blocks 2.4 GHz. The booster or the base has to sit close. A Smoke-style transmitter outside the cooker never had to punch the signal out through the meat.
Is Sub-1G the same as 915 metres in a terrace?
No. 915 m is the X2 bullet. One United Kingdom review lost that link at 30 m through walls. Use the review, not the open-field number, when the walls are brick.
What dies first, the cable or the probe battery?
In this file the wireless probes are the ones that stop pairing or charging after months. Cables fail when they are burnt, cut or pinched. AA life on the Smoke is the manufacturer’s figure of about 1,800 hours, not something we timed.
Can I leave the house on Wi-Fi if the probe is only Bluetooth?
No. Phone Bluetooth on these United Kingdom reviews often dies in the garden, not at 135 m. Wi-Fi on the G2 is a hop from the base, and the base still has to hear the probe. The X2 has no Wi-Fi.
Which of these listings is actually wire-free?
TempSpike TP961, ThermoMaven P1, G1, X2 and G2, and the Inkbird four-probe set. The TP17, TP904 and SENSTREE are cabled to the box. The Smoke is wireless only as far as the receiver.
