  • This release fixes an issue that prevented some ovens from completing the firmware update process reliably.

  • Fixes an issue in newer ovens where the temperature unit reverts from C to F after unplugging.

  • If you're having issues updating to the latest firmware, please unplug your oven for 5 minutes, plug it back, then update the firmware.


  • Changing stage properties on the app after a cook has started no longer creates an error.
  • Holding the start/stop button does not immediately initiate a Stop request after starting a cook unless it’s held at least 5 seconds (up from 1 second).
  • Improved stability
  • The temperature display no longer reverts to F after reboot.


What's New:
  • Major improvements in connectivity and app pairing through WiFi.
  • Oven now remembers the last five temperature settings when set from the handle and will pause on these temperatures when pressing and holding the up/down temp buttons on the oven handle.
Bug Fixes:
  • Oven no longer crashes during a firmware update.
  • Oven handle no longer reports a slightly different temperature than the app when displaying Fahrenheit (rounding error).
  • UI no longer locks up or stops playing all sounds when adjusting cook settings on the handle.
  • Light no longer flickers after ending a cook.
  • Adding timer from oven handle no longer affects the fan setting.
  • During a connected cook, the play button now stays blue, even after manually advancing the stage.


New Features:
  • The back of the handle sensors are disabled. What this means is that you can rest your hand fully on the handle to make adjustments to time, temp, and steam settings without causing the handle to be unresponsive due to hand placement.
  • At the end of your cook with a timer or probe setpoint, the oven will now repeat the "finished" sound 5 times to alert you that the cook has completed.
  • After finishing a cook, the oven handle lights will go into standby after 5 minutes instead of 20 minutes.
  • If the steam is at one of the extremes (0 or 100%), tapping + or - at the extreme end of the steam setting will loop back around. Example: pressing - when at 0% will loop to 100%.
  • If the temp is at one of the extremes, tapping + or - at the extreme end of the temp will loop back around.
  • Temperatures under 212F/100C will increment/decrement at 0.5 degrees F or 0.1 C.
  • Changes to the temperature and timer press and hold behavior with the intent to help you arrive at your desired temp or time with more accuracy.
  • Button presses on the oven handle are more responsive.
  • When performing a manual cook from the oven handle, the oven will chime when the pre-heat target is reached. If you adjust the setpoint target to another, higher, setpoint, the oven will chime again once preheated to the new setpoint.
Bug Fixes:
  • Changing the heating element during a cook from the oven handle will now properly be reflected in the app's oven tab.
  • The heating element icons on the oven handle will light back up after running descale instead of remaining off/dark.
  • Starting a manual cook from the app with Sous Vide mode on, no steam, any element selected except for convection now supports fan off.
  • Other internal bug fixes and improvements to over-the-air update capability and diagnostic reporting.
  • Internal error checking to verify heating elements operations.
  • While the oven door is open, the light may turn off due to being unplugged or briefly at the end of a cook; however, the light now turns back on if the door is open and the oven is plugged in.
