Power up!

Stay ready so you don’t have to get ready. This Combustion Booster extends Bluetooth range and allows you to recharge your Predictive Thermometer even when you don’t have access to USB power.

Perfect for smoking, grilling or other outdoor cooking - the Booster helps you overcome radio obstacles like thick-walled metal smokers and grills.

Charge your tools

Charge the Booster (60 min).

NOTE: Don’t insert the thermometer yet!

⚠️ Putting a thermometer into the Booster shuts the radio off! Removing it turns the radio on.

⚠️ NOTE: use standard 5v USB ports/power supplies only.

Update firmware

  • Download the Combustion Inc app from the App Store for iOS or Google Play for Android. 
  • Unplug the Booster from the USB
  • Don’t insert a thermometer yet!
  • Tap the Combustion logo on the app
  • Tap update
  • Recharge the Booster after updating

Note: please do not update more than one Booster (or other Combustion tool) at the same time. Leave the other ones powered off (or in standby) while you update. It doesn't take long!

Power off the Booster by holding the button (1 sec).

Link your thermometer

  • Unplug the Booster from the USB
  • The light will flash white 3 times in a row to show it’s searching (this sequence repeats)
  • Hold a (fully charged) thermometer near the Booster 
  • A single white blink indicates the link has been established (it will blink every 5 seconds)
Illustration of proximity linking. Put all your Combustion tools (and your mobile device) close together and allow them to link.

Link all tools (multi node MeatNet™)

To share signals correctly, all of the Combustion Tools involved must be linked.

Start by updating the firmware on all devices* (if you haven't yet).

Then do this:

  • Put Thermometers in Boosters (this turns the Booster radio off) and turn off Display (hold start/stop)
  • Put all devices within a couple inches of each other
  • Remove Thermometers from Boosters and turn on Display, and set Thermometers in the pile of devices
  • Let all devices sit for 1-2 minutes
  • That's it! They're all linked together and will relay signals from all linked Thermometers
  • Each Booster can be linked to up to four Thermometers

⚠️ Yes, this works with multiple Boosters, with or without a Display.

Connect to WiFi (optional - WiFi Booster)

If you have the (2nd Gen) WiFi Booster then you'll want to follow the steps on the WiFi start page to get it connected to your local network.

The WiFi Booster acts as a gateway, connecting any Predictive Thermometer (or Gauge) to local WiFi. With that you can send temperatures and other thermometer data to the cloud - and stream it to your phone or tablet (and some Mac computers).
