Bookoo Espresso Monitor Pressure Sensor

Master your extraction with the Bookoo Espresso Monitor. This compact and intelligent upgrade to your machine brings your espresso shots into sharp focus, offering real-time pressure data and intelligent Bluetooth connectivity. Designed for home enthusiasts and pros alike, it turns each brew into a data-rich experience. With dynamic pressure tracking, flow rate integration and mobile app support, this compact sensor unlocks the hidden variables of your extraction. 

Real-Time Pressure, Real Insight

Capture live pressure data as your shot pulls, directly from the grouphead. The Bookoo Espresso Monitor uses a highly sensitive sensor to read water pressure in real time, giving you feedback as you brew. Whether you’re troubleshooting under-extracted shots or fine-tuning pre-infusion, this tool makes the invisible visible. With every adjustment, you’re building a more consistent, dialled-in espresso.

Intelligent App Integration

Pair the sensor with the Bookoo App or Beanconqueror via Bluetooth for a full visual breakdown of each shot. Watch extraction curves unfold in real time, then review, compare and save your favourites. Build a library of custom pressure profiles, replicate pro-level extractions, or share results with other baristas. You can create multi-phase pressure maps for layered flavour exploration – turning your espresso into a canvas. 

Expand the Data with Scale Compatibility

Go beyond pressure. The monitor integrates with Bluetooth-enabled coffee scales like the Bookoo Themis Mini, Acaia and Felicita. This connection pulls in real-time weight and flow rate data to round out your shot analysis. When paired with the Bookoo Mini Scale, the system also calculates coffee-to-water ratio and powder resistance, which is perfect for tech-savvy brewers looking to optimise every variable. 

Ready to Connect

Compatible with G1/8 thread machines such as the Flair58 and equipped with an M6 adapter for E61 groupheads like those on Lelit Bianca, ECM Mechanika and Profitec Pro series machines. This sensor slips seamlessly into your setup with minimal fuss. Once installed, it activates automatically and gets to work – no complex calibration or fiddly settings.
