ThermoWorks BlueDOT Food Thermometer Review
The ThermoWorks BlueDOT is a Bluetooth-enabled version of the venerable DOT thermometer family. It has a single temperature probe and works with or without a free app that can control and monitor the product. The Bluetooth transceiver can be turned on and off to save battery life.
Operating the BlueDOT is simplicity itself. The on/off button, located on the back of the unit, has three functions: power on/off, backlight activation, and scale selection (ºF/ºC). Two buttons on the front select the upper alarm temperature and allow the user to disable the alarm function. (The alarm value can also be set via the app.) A lower alarm temperature can also be set, but only via the app. When either alarm temperature is reached, the unit emits a loud beep, the backlight turns on, and the temperature flashes. The display indicates which alarm temperature has been tripped, upper or lower. The alarm function can be disabled, if desired.
The app can display the current temperature, the alarm values, and a min/max range. There is a graphing function as well, and the graphical data can be saved and exported in a csv format.
Both upper and lower alarms can be set in the app, and the min/max values can also be reset there. When an alarm threshold is crossed, the app displays which alarm is sounding, and gives the user the option to mute the alarm. Muting takes place in both the app and on the device. One or both alarms can be disabled from within the app.
The instruction sheet is complete and clearly written. Contact info for the manufacturer is included should technical assistance be needed. Warranty is five years.
This is another well-made product from ThermoWorks. Both build quality and performance are excellent. Another Gold Medal!

High quality websites are expensive to run. If you help us, we’ll pay you back bigtime with an ad-free experience and a lot of freebies!

Millions come to every month for high quality tested recipes, tips on technique, science, mythbusting, product reviews, and inspiration. But it is expensive to run a website with more than 2,000 pages and we don’t have a big corporate partner to subsidize us.

Our most important source of sustenance is people who join our Pitmaster Club. But please don’t think of it as a donation. Members get MANY great benefits. We block all third-party ads, we give members free ebooks, magazines, interviews, webinars, more recipes, a monthly sweepstakes with prizes worth up to $2,000, discounts on products, and best of all a community of like-minded cooks free of flame wars.

1) Please try the search box at the top of every page before you ask for help.

2) Try to post your question to the appropriate page.

3) Tell us everything we need to know to help such as the type of cooker and thermometer. Dial thermometers are often off by as much as 50°F so if you are not using a good digital thermometer we probably can’t help you with time and temp questions. Please read this article about thermometers.

4) If you are a member of the Pitmaster Club, your comments login is probably different.
