Why is the LED on my Joule blinking and what does the light color mean?

The LED on your Joule uses different colors and patterns to communicate the state of your cook. Here’s an overview:

Solid white light: Joule is in standby mode. If you’re already connected to Joule, this means that Joule is ready to start cooking.

Blinking white light: Joule is ready to pair. Press the top of Joule to continue.

Double-blinking white light: The Joule app has requested that Joule identify itself.

Slowly blinking, or “breathing,” orange light: Joule is heating to its set temperature.

Double-blinking orange light: Power was lost during cooking. If you unplug Joule while it is cooking, you may see this when you plug Joule in again.

Solid green light: Joule has reached the set temperature and is holding steady.

Double-blinking green light: A timer has completed its countdown. Your food is probably done!

Solid yellow light: A system failure has occurred. Try unplugging Joule and plugging it back in again.

Double-blinking yellow light: A factory reset is in progress.

Blinking blue light: A software update is downloading to Joule.

Solid blue light: A software update has been downloaded to Joule and is being installed. After the update has installed, Joule will restart and show a solid white light.

Double-blinking red light:  There is an issue with Joule. Check the Joule app for more information. View additional troubleshooting for this state here.

Solid red light: There is a Joule software error. The device should reset itself in this case. If it does not, attempt to reset Joule by unplugging it for at least 10 seconds and then plugging it back in.
