Acaia Umbra

The Acaia Umbra is a minimalist, ultra‑precise, display‑free weighing scale — designed to integrate seamlessly with other Acaia scales or work independently via a smartphone app. It leverages Acaia’s industrial‑grade weighing technology to deliver real‑time, highly accurate measurements, making it ideal for both home espresso setups and commercial coffee bars.

• Magic Relay Function: Shares readings between Umbra and other Acaia scales. When weight shifts on one scale, the paired display updates instantly.
• Ultra‑Precision Weighing: 0.1 g readability, 1,000 g max capacity, and high repeatability.
• Energy Efficient: No built-in display means lower power consumption — up to 40–48 hours of active use, or 14 days in standby mode.
• Durable Build: Crafted from anodized aluminum for excellent stability and water resistance.
• Flexible Connectivity: Connects via Bluetooth Low Energy (BLE 5.4) to your phone or other Acaia devices.
• Multiple Modes: Supports advanced bar workflows, including dual-scale monitoring.
