Use the built-in rechargeable battery or plug into an AC power outlet with USB. The scale automatically turns on - and stays on - with AC power.
Connects to the DE1 app so you can set additional weight-based features. Espresso shots will automatically stop at your specified in-cup weight.
Works with these third-party apps in addition to Decent apps:
Beanconquerer | Act Four | Filtru | Espresso Log | Smart Espresso Profiler | Pressensor | PyDecentScale | Color bar manager | de1app
Wide enough to weigh two cups at once: 14mm (height) x 103mm (depth) x 158mm (width). The slim profile is slightly thinner than the popular Acaia scales and fits into a drip tray.
Super simple BLE API, Javascript code, Python library. Bluetooth, USB and Wifi support.
