What is a firmware update and do I need it?

Firmware is the software that makes your scale run, weigh, and have different modes and settings. Over the years, there have been a handful of different firmware which has introduced new modes and bug fixes to our scales.

Downloading the latest firmware gives you access to the latest modes and smoothest functionality for your scale.

The current most recent firmware versions are:

Acaia Pearl

  • 2.0 Option A & B
    • Option A has as many modes available as Option B, but only Weighing Mode, Weighing + Timer mode, and Auto-Tare mode are enabled. To turn the rest on, you would have to access the settings menu
    • Option B has all modes available

Acaia Lunar
