  • We added code to detect a heater error


Version 123.52 of Joule’s software is here!

  • We removed some code that was no longer needed.


Version 122.52 of Joule’s software is here!

  • Fixed another issue with reporting cook times.


Version 121.52 of Joule’s software is here!

  • Fixed an issue with reporting cook times.


Version 116.52 of Joule’s software is here!

  • Fixed incorrect LED state during pre-heat.


Version 112.52 of Joule’s software is here!

  • Fixed incorrect LED state during pre-heat.


Version 108.52 of Joule’s software is here!

  • The timer is better behaved in noncook states and error situations.


Version 107.52 of Joule’s software is here!

  • Updates to how Joule lets you know about stuck motors.

  • New features to enable the cook timeline view.


Version 103.52 of Joule’s software is here!

  • Increased the baud rate for faster boot times.

  • Added support for multiple WiFi profiles.

  • Other various bug fixes.


Version 89.39 of Joule’s software is here!

  • Joule is now less aggressive in detecting whether or not motors are performing to spec.


Version 87.39 of Joule’s software is here!

  • Joule is now less aggressive in detecting whether or not heaters are performing to spec.

  • We made it even more difficult to inadvertently factory reset the circulator.


Version 85.39 of Joule’s software is here!

  • Joule is now better at detecting when hardware (motor, heater) is not performing to spec.

  • Better handling of transient errors (such as when the pot is out of water or Joule is tipped over).

  • More information returned about errors and power loss to the Joule app, including timestamps.

  • Changed the Bluetooth handshake process so Joule connects to the app more quickly.

  • Made it harder to accidentally trigger a factory reset.

  • Added identification information for both white and stainless Joules.

  • Exposed the WiFi MAC address of the circulator.

  • Improved WiFi connections: faster TLS/SSL handshake, more-robust WiFi connections, support for 63-character passwords and 32-character SSIDs.

  • Removed support for beta Joules.

  • Joule won’t appear as connectable on a phone if another phone is already connected via Bluetooth.

  • Fixed various other bugs, including some crashes and out-of-memory conditions.


Version 61.23 of Joule’s software is here!

  • Connectivity improvements.


Version 61.22 of Joule’s software is here!

  • Joule’s maximum operating temperature has increased.

  • At sea level, Joule can now reach a max temperature of 208 °F / 98 °C.

  • If you live at high altitude, the max is 3.6 °F / 2 °C less than your local boiling point.

  • The heater now power cycles faster to keep Joule nice and quiet.

  • Joule’s temperature is now even more accurate.

  • A power loss will now cause the LED to blink orange.

  • We’ve improved the motor controller.

  • Oh, and the team squashed a few bugs while they were at it.
