The deciding specification is whether the device controls anything at all, because only two of these five drive a fan into the fire.
By the Lush Editorial Team·Researched & Compared
I compared what each device actually controls, probe counts, published accuracy and temperature ranges, power sources and wireless range across five listings sold as barbecue temperature controllers.

A self adjusting 5.0 m/s fan with three meat probes and an oven probe accurate to plus or minus 0.9 F, WiFi and Bluetooth, a lid detector, and 5V USB power.

The only listing that publishes the vent opening it fits, a sliding lower door between 2-3/4 and 3-3/4 inches, with a large adjustable kamado adapter in the kit.

A 110V relay rated 10A with an 1100W limit, switchable between heating and cooling, with alarms, calibration and a waterproof probe on a 9.8 ft lead.

Two probes accurate to plus or minus 0.5 F at 0.01 F resolution, Sub-1G radio giving 3000 ft clear and 700 ft obstructed, and a base that works with no app.

An infrared gun reading -58 to 842 F in under half a second, with a 12 to 1 distance to spot ratio and a stated 14.17 inch working distance.

Inkbird and pitmasterIQ are the only two here that hold a temperature, both by throttling a fan into the coals. Inkbird publishes four probes accurate to plus or minus 0.9 F and runs on 5V USB. pitmasterIQ is the only one that publishes the vent it fits. bayite switches a mains appliance instead. ThermoMaven and Etekcity measure only, to plus or minus 0.5 F and 842 F respectively.

Inkbird and pitmasterIQ, and no others. Both read the air inside the cooker and run a fan into the lower vent to feed the coals when the temperature falls. Inkbird states a 5.0 m/s fan that adjusts its own speed, and pitmasterIQ claims 225 degrees for up to 8 hours on one load of charcoal. bayite controls a mains appliance instead, and the remaining two only measure.
Because the search term and the products have drifted apart. Etekcity reads a surface from a distance, from -58 to 842 F with a 12 to 1 distance to spot ratio, which makes it genuinely useful for checking a grate or a pizza stone before food goes on. What it cannot do is change anything, and it cannot tell you the inside of a piece of meat either.
Only one listing here lets you check. pitmasterIQ publishes the vent it needs, a sliding lower door with a height between 2-3/4 and 3-3/4 inches, and names the cookers by model including Big Green Egg, Primo, Kamado Joe and the Vision grills. Inkbird names cooker types in its title but publishes no dimensions at all, so the physical fit is unanswered.
ThermoMaven, on the published figures. It states plus or minus 0.5 F with 0.01 F resolution and six NIST certified sensors per probe, five internal and one external. Inkbird states plus or minus 0.9 F across four probes with a calibration offset of up to plus or minus 12 F. The other three publish no accuracy figure at all, which on a measuring device is a significant omission.
No, and that is not a fault in the product. bayite switches a 110V appliance on and off through a relay rated 10A with an 1100W limit, so it needs something electrical to switch. Charcoal has nothing to switch. Put it on an electric smoker, a fermentation chamber, a heat mat or a warming cabinet and it is the right tool, and its range of -4 to 230 F suits exactly those jobs.
Two different answers. ThermoMaven uses Sub-1G radio rather than Bluetooth, publishing 3000 ft unobstructed and 700 ft through obstacles, and its base shows readings and sets targets with no app involved. Inkbird uses 2.4GHz WiFi with Bluetooth 5.0, so range is your network, several phones can watch one cooker, and it downloads a temperature graph and a fan output graph.

Only two of these five control a temperature. Inkbird and pitmasterIQ both blow air into a charcoal fire and throttle the fan to hold a target, which is what a controller is. bayite switches a mains appliance on and off through a relay, which is control of a different kind. ThermoMaven and Etekcity only measure, and no amount of measuring changes what a fire is doing.
That is not a criticism of the last three, it is a warning about how this category is listed. If you are buying something to keep a kamado at one temperature overnight, two products on this page do that job. The other three are useful tools that will tell you accurately how far off target you already are, which is a different purchase.

What the table cannot tell you is how tightly either fan controller actually holds a target, because neither publishes a deviation figure for the thing they exist to do. Inkbird publishes probe accuracy of plus or minus 0.9 F, which is a measurement claim, not a control claim. pitmasterIQ publishes a duration and a temperature but nothing about the swing around it.
Inkbird and pitmasterIQ work the same way. A probe reads the air inside the cooker, and when the temperature drops the controller runs a small fan into the lower vent to feed the coals. Charcoal responds slowly, so the work is in throttling the fan rather than switching it, and Inkbird states that its 5.0 m/s fan adjusts its own speed to the ambient reading.
pitmasterIQ takes the mechanical side more seriously. It ships a large adjustable kamado adapter and publishes the vent opening it fits, a sliding lower door between 2-3/4 and 3-3/4 inches, then names the cookers by model. That is the specification that decides whether the kit physically mounts, and it is the one thing Inkbird’s listing does not give you at all.
bayite is a controller, just not a barbecue one. It is a 110V relay box rated to 10A with a 1100W load limit, an NTC 10K probe on a 9.8 ft lead, and a switch between heating and cooling mode. On a charcoal cooker it has nothing to switch. On an electric smoker, a fermentation chamber or a heat lamp it is exactly the right tool and reads from -4 to 230 F.
ThermoMaven and Etekcity measure and stop there. ThermoMaven is a two probe wireless meat thermometer with a display base, and Etekcity is an infrared gun that reads a surface from a distance. Both are genuinely good at what they do and neither will hold a fire at 225 degrees. They appear in this category because the search term and the products have drifted apart.
ThermoMaven publishes plus or minus 0.5 F with 0.01 F resolution, and says each probe carries six NIST certified sensors, five internal and one external. That is the most detailed sensing claim on this page by a distance, and the resolution figure is the kind of number only a company confident in its probes prints.
Inkbird publishes plus or minus 0.9 F across all four of its food grade stainless probes, plus a calibration offset of up to plus or minus 12 F if a probe drifts. Nobody else publishes an accuracy figure at all: not pitmasterIQ, not bayite, and not Etekcity, which is the one product here where accuracy depends on how you hold it.
Etekcity reaches 842 F, the highest figure on this page, and starts at -58 F, so it covers a pizza stone and a freezer with the same tool. That range is only available because it never touches anything. Inkbird’s probes cover 32 to 572 F, which spans every barbecue temperature and the grate above the coals as well.
The two lower ranges tell you what their products are for. ThermoMaven publishes internal meat temperatures up to 221 F, which is everything you would ever cook to and nothing more. bayite reads -4 to 230 F, a range built for fridges, fermenters and warming cabinets rather than for fire, which is another sign it landed in this category by keyword rather than by design.
Inkbird runs on 5V USB and says explicitly that any power bank will do, which matters because a controller has to run for the whole cook and a grill is rarely near an outlet. pitmasterIQ ships for AC operation and sells a 12VDC cigarette lighter adapter separately, which is the same problem solved with a different accessory.
bayite needs 110V mains by definition, since it is switching mains through a relay. ThermoMaven charges its base in 2 hours for over 24 hours of use, and its probes take 2 minutes for 2 hours, which is the most specific power claim here. Etekcity takes 2 AAA cells and includes them, which is the right answer for a tool you pick up twice a cook.
ThermoMaven publishes 3000 ft unobstructed and 700 ft through obstacles using Sub-1G radio rather than plain Bluetooth, and the 700 ft figure is the honest one, because a house wall is an obstacle. It also has a display base that shows readings and sets targets without an app, which is the feature that matters when your phone is on charge indoors.
Inkbird uses 2.4GHz WiFi alongside Bluetooth 5.0, so the range is your network rather than a number, and it can be monitored by several phones or several cookers from one phone. It also downloads a temperature graph and a fan output graph, and detects when the lid is open so the fan stops feeding the fire while you are working.
A kamado you want to leave overnight. Inkbird. A self adjusting 5.0 m/s fan, three meat probes and an oven probe accurate to plus or minus 0.9 F, WiFi and Bluetooth, a lid detector that pauses the fan, and 5V USB power from any power bank.
A Big Green Egg or a Primo. pitmasterIQ. The only listing here that publishes the vent it fits, a sliding lower door between 2-3/4 and 3-3/4 inches, and names the cookers by model. It claims 225 degrees for up to 8 hours on one load of charcoal.
An electric smoker or a fermenter. bayite. A 110V relay rated 10A with an 1100W limit, switchable between heating and cooling, with high and low alarms, compressor delay protection, calibration, and a waterproof probe on a 9.8 ft lead reading -4 to 230 F.
Watching the meat from indoors. ThermoMaven. Two probes accurate to plus or minus 0.5 F at 0.01 F resolution, Sub-1G radio giving 3000 ft clear and 700 ft obstructed, IPX8 dishwasher safe probes, and a base that works with no app at all.
Checking the grate before the food goes on. Etekcity. An infrared gun reading -58 to 842 F in under half a second, with a 12 to 1 distance to spot ratio, a stated 14.17 inch working distance, a backlit screen, and the lightest body here at 0.25 lb.
Six things a buyer would reasonably ask that these five listings never answer.
