Meticulously designed for baristas who value precision, connectivity and clean workflow, the Acaia Umbra Lunar Coffee Scale is the most advanced addition to the Acaia ecosystem. Engineered without a display, it wirelessly syncs via Magic Relay with the Acaia Lunar or the Acaia App, delivering real-time weighing data with 0.1g accuracy. Compact, durable and water-resistant, it brings the next generation of precision brewing to any espresso bar or home setup.
Intelligent Connectivity
Seamlessly integrating with Acaia’s smart brewing network, the Umbra Lunar transforms how weight data is shared, displayed and logged. Its display-free interface keeps your bench uncluttered while maintaining total control through your connected device or paired scale. With Magic Relay technology, you can monitor weight in real time, track flow rates and store data for repeatable extractions. Built to work effortlessly alongside the new Lunar, it redefines precision through intelligent connectivity.
Refined Design and Lasting Performance
Machined from anodised aluminium with an elegant matte finish, the Umbra Lunar is both water-resistant and espresso-proof. It maintains the same 0.1g precision found across Acaia’s range, yet in a smaller, more efficient body. Designed for commercial reliability, its rechargeable lithium-ion battery offers up to 48 hours of continuous use and charges quickly through USB-C. The Umbra Lunar’s modern design ensures durability and performance that matches its minimalist beauty.
