Minor Firmware Update

Adjusted Lunar Auto-Tare Function for Orbit


  • Lunar Auto-Tare: in response to user feedback, we have adjusted the Lunar’s Auto-Tare function when linked to the Orbit. The Auto Tare on/off toggle has moved from the Grind-by-Weight mode to the Manual mode on the Orbit. This modification helps to prevent unwanted activation of the auto-tare function.




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.
