Wireless Controller Firmware Update (May 2024)


WIFI Connectivity

  • This firmware update specifically addresses issues where the WIFI connection could randomly disconnect and only connect again once the power was unplugged (power turned off) and then turned back on.
  • The update is to the Wireless module (updating to version esp32-14). It is not updating the controller (grill operation) software.
  • The update will automatically appear in the App (see screenshots below) once available for your grill model.
