Lunar 2021 Firmware Updates Versions

This article is for the updates for the Lunar 2021. For the original Lunar scale, please see this article here.



Date released: 7 September 2023

Major Firmware Update

New Mode: Pour Over Mode.


  • New Mode: Pour Over Mode.

  • Workflow for this mode is identical to the Pour Over Auto-Start Timer Mode in the Pearl 2021. The Flow-Rate Indicator is optimized for Pour Over.


  • In Pour Over Mode (Mode 7), when the scale detects the flow of water into the vessel, the timer starts. The timer stops when the brewing equipment is removed from the scale. The mode detects the flow from a kettle rather than the trickle of espresso. The Flow-Rate Indicator is also modified to suit pour over brewing. Each dot represents 0.2 g/s, and the final 3 dots indicates 8.0 g/s, 10.0 g/s, and 12.0 g/s.
  • The mode is represented by a circle + droplet on the right side of the LED screen.
