Frequently Asked Questions

+
Why not just get a regular wireless digital thermometer?
Because you'd be missing out! The Spark's WiFi connectivity enables remote temperature monitoring via the FireBoard app. Its integration with cloud services and leave-in probe port facilitates remote access to cooking data and temperature logs, allowing for flexibility and control when cooking. Backed by an active user community and our dedicated in-house customer support, the FireBoard Spark is a top choice among other smart meat thermometers in the market.
+
How fast are the Spark's temperature readings?
The Spark will record temperatures in approximately one second. You can read more about how the thermometer's sensor works in our blog article about instant-read speeds.
+
How do I calibrate the FireBoard Spark?
The Spark thermometer comes pre-calibrated, but you can verify its accuracy by performing a simple ice water calibration or using a reference thermometer to ensure precise temperature readings. Check out our thermometer calibration documentation for more information.
+
Can I leave the FireBoard Spark digital meat thermometer probes in the oven or grill?
Yes, the leave-in probes are heat-resistant and suitable for use in ovens, smokers, grills, and other cooking appliances. However, ensure that the cables are positioned away from direct heat sources to prevent damage.
+
Is this thermometer waterproof?
Yes, the Spark has been approved for an IP66 Waterproof Rating. We've engineered watertight seals on the body of the Spark, the swiveling instant-read probe, and the external probe port so you can wash it confidently. However, it is not safe for total submersion or placement in dishwashers.
+
How do I clean the FireBoard Spark thermometer probes?
Clean the thermometer probes with warm, soapy water after each use. Avoid fully submerging the probes in water, and gently wipe the probe cables and connectors with a damp cloth. Avoid exposing the probes to excessive moisture.

Make life easier

I've been cooking on a Green Egg for almost 30yrs. and have eyeballed various temp. control systems, though I'm very proficient using the vents. Meanwhile I bought a Yoder YS640 which uses Fireboard as their control system. I was impressed with it on the Yoder with its information and options. So I took the plunge and purchased a fireboard 2, the vent fan, and Spark thermometer. The items integrate onto the App with the Yoder and make everything a breeze, especially if your doing multiple cooks at once. Recently we bought my daughter and son-in-law a Kamado Joe as a house warming gift. Also got them a Spark with a couple probes ,because it has wifi and you can plug a probe into it to either monitor the smoker or food temperature.
Told them I would get familiar with the smoker using the vents, and then consider getting the Fireboard 2 , especially for overnight cooks.
Comes down to this, if you cook and want guaranteed ,consistent results, that are achieved with the least trouble and inconvenience. Then get the Fireboard products. But don't take my word, get online, (YouTube etc.) and do your research. Then make the purchase, follow the instructions, and enjoy effortless results. It really is a no brainer. You will be so happy with your purchase your wife will be suspicious of your happy grin as you sip your drink of choice while multi tasking, (or watching the game).

Amazing solution!

I love the integration of this thermometer. Last use, I had it display my Fireboard2 temps, including a pulse probe, on my refrigerator (magnets!) so that I could check on two briskets at once as well as the smoker temps.

When it was close to finishing, I used the built in probe to test other portions of the brisket to ensure it was really done before pulling them off the smoker. Awesome tool.
