The short answer: the Weber Connect Smart Grilling Hub monitors your grill — it reads temperatures and sends alerts to your phone, but it can't change anything. The BBQube TempMaster Pro controls your grill — its variable-speed fan feeds the charcoal exactly the air it needs to hold your target pit temperature for hours. One is a thermometer with an app; the other is a thermostat for your smoker.
What's the real difference between Weber Connect and BBQube TempMaster Pro?
Both devices put your grill's temperature on your phone, and that's where the similarity ends. Weber Connect is a monitoring-only hub: it watches, records, and notifies. The TempMaster Pro is a closed-loop temperature controller: it watches, and then it acts — speeding up or slowing down its fan to raise or lower the fire.
A Weber Connect tells you when your pit temperature drifts. A TempMaster Pro keeps it from drifting in the first place.
If you've ever wondered why your kettle temperature spikes or sags mid-cook, this distinction is the whole story: alerts don't fix a fire. Airflow does.
What does the Weber Connect Smart Grilling Hub actually do?
Weber Connect is a small Wi-Fi- and Bluetooth-enabled hub with four probe ports (it ships with an ambient grate probe and a meat probe). Paired with the Weber Connect app, it gives you:
- Live pit and food temperatures on your phone
- Guided cooking programs with step-by-step instructions
- Flip reminders, doneness alerts, and a food-readiness countdown
- Compatibility with virtually any grill — gas, charcoal, or pellet
What it will not do is move a single molecule of air. There's no fan and no vent motor. If your charcoal pit drops to 185°F at 3 a.m. during an overnight brisket, Weber Connect will faithfully notify you — and then you're the one outside in your slippers nudging the bottom vent. It also runs on a rechargeable battery, so for an all-night cook you'll want it topped up or plugged in.
What does the BBQube TempMaster Pro do?
The BBQube TempMaster Pro pairs a multi-probe thermometer with a variable-speed fan that mounts to your grill's air intake via a grill-specific adapter. You set a target — say, 225°F — and the controller does the rest:
- The pit probe reads the actual temperature, continuously
- The fan pulses faster to feed the coals oxygen when the pit runs cool, and eases off when it runs hot
- The result is a steady pit temperature held for hours, monitored from the phone app
- A sous-vide mode extends that same precision to low-temperature water-bath cooking
It fits the Weber Kettle, Weber Smokey Mountain, Big Green Egg, Kamado Joe, Akorn Kamado, and most other close-lid charcoal grills through its adapter system. One honest caveat: it's built for charcoal. It is not a pellet-grill controller, and it's not for gas grills.
Why does fan control matter so much for low-and-slow charcoal?
A charcoal fire's throttle is oxygen. Fuel is fixed once you've lit it; the only lever left is airflow. That's why the classic manual craft works the way it does:
- Bottom vent in small nudges — a quarter-inch change, then wait 10–15 minutes to see the effect
- Top vent mostly open — let smoke and heat exit freely so the fire breathes clean
- Snake or Minion fuel layouts — so the coals light gradually and burn at a predictable rate
Learning those skills makes you a better cook, and we recommend every charcoal griller learn them. But even a skilled hand can't outrun a gust of wind, a charcoal load burning past its peak, or a lid lift to spritz ribs. A fan controller makes those micro-corrections constantly — dozens of small adjustments while you're asleep, at your kid's game, or actually talking to your guests. That's the lifestyle payoff: overnight brisket without the 3 a.m. vent check, and repeatable results cook after cook.
Which one should you choose?
Weber Connect makes sense if you:
- Grill mostly on gas and want guided, step-by-step cooking help
- Prefer to manage charcoal vents yourself and just want remote alerts
- Do shorter cooks — steaks, chicken, chops — where drift is less punishing
The BBQube TempMaster Pro makes sense if you:
- Cook low-and-slow on charcoal — brisket, pork butt, ribs — for 8 to 16 hours
- Want set-and-forget temperature holding, not just alerts
- Value your sleep and your time with family more than vent babysitting
And because the TempMaster Pro already includes multi-probe monitoring with phone-app tracking, it covers the Weber Connect's core job for charcoal cooks — then adds the control layer on top.

FAQ
Does the Weber Connect control grill temperature?
No. Weber Connect is monitoring-only — it reads probe temperatures and sends app alerts and guided-cooking prompts, but it has no fan and no way to adjust vents or airflow. Any temperature correction is still done by hand, by you.
Can the BBQube TempMaster Pro monitor temperatures like Weber Connect?
Yes. The TempMaster Pro includes a multi-probe thermometer with phone-app monitoring, so remote temperature tracking is built in. The difference is that it also acts on that data, driving its fan to hold your set point automatically.
Will the TempMaster Pro work on a gas grill or pellet smoker?
No. It's a fan-driven controller for charcoal grills with closable lids — Weber Kettle, Weber Smokey Mountain, Big Green Egg, Kamado Joe, Akorn Kamado, and similar cookers via grill-specific adapters. It is not a pellet-grill controller and doesn't apply to gas grills.
Is Weber Connect good for an overnight brisket on a charcoal smoker?
It will watch the cook and alert you when temperatures drift, which is better than nothing. But it can't correct the drift — you'll be getting up to adjust vents yourself — and you'll want the rechargeable battery topped up or plugged in for a cook that long.
Do I still need to learn vent control if I buy a fan controller?
Yes, and it will make you a better cook. Understanding how the bottom vent, top vent, and fuel layout shape your fire helps you set up every cook correctly. The controller simply takes over the hundreds of tiny corrections that would otherwise keep you tethered to the smoker.
