Know before you buy
The Smart Espresso Profiler is compatible with E61 group head machines that utilize an M6 thread. Please verify your specific machine's thread size before purchase to ensure a proper fit.
While the profiler can record pressure data on its own, the Acaia Lunar scale is required if you want to capture flow rate, weight, and brew ratio data. Without the scale, you will be limited to pressure and time metrics.
The profiler features an automatic trigger that begins recording as soon as the pressure reaches 0.8 bar. This ensures your data capture is consistent and starts exactly when the extraction begins.
Yes, the companion app allows you to set a previous brew as a reference profile. You can then use this as a guide to help you replicate the pressure and flow characteristics of your best shots.
Installation is designed to be straightforward, involving mounting the transducer directly to your machine. No specialized technical skills are required, though you should be comfortable performing basic maintenance on your espresso equipment.
Absolutely. The companion app includes built-in functionality to log your brew history and share your successful extraction profiles with other users, making it easy to collaborate or compare techniques.
