See inside every shot.
Real-time pressure and flow, shot by shot. The Pressensor clips onto your espresso machine and streams live data to your phone as you pull.
Finally, the shot makes sense.
You’ve weighed the dose. You’ve dialled in the grind. You’ve tried every variable you can think of. But when the shot tastes off, you’re still guessing.
The Pressensor screws onto your machine’s pressure port and streams live data to your phone as you pull. See the pre-infusion plateau. Spot the channeling spike. Watch how your grind changes the curve — shot by shot, in real time.
Now you know exactly what happened. And next time, you make it better.
Three things. The whole picture.

A scale (optional but lovely)
Find my setupPair the Pressensor with a Bluetooth scale and get flow rate too — how fast the water moves through the puck, alongside how hard it’s pushing. Supports Acaia, Felicita and others.
The app you’ll actually use.
We built it for the way coffee people actually think. You’re not here for spreadsheets. You’re here because you want to pull better shots.
Watch the curve build in real time. Save your favourites. Compare extractions across different beans, grind settings, temperatures. Spot the patterns that took months to notice — now you’ll see them in a week.
Used by everyone from first-time E61 owners to competition-level home baristas. Free to start. Pro features coming in 2026.
Your machine, connected.
The Pressensor fits any machine with an E61 grouphead — the most common grouphead in the world. Rocket, Bezzera, ECM, Profitec, Lelit, Vibiemme — if it has an E61, we have it covered.
We also have what you need for the La Marzocco GS/3, the Olympia Express Mina, the Flair lineup, the Newton Brua3 Max and the Leverpresso Pro. Not sure which one you need? Start with your machine — we’ll point you to the right kit.
Want to go deeper?
The Pressensor ecosystem goes further than the sensor itself.
Splitter — connects both the Pressensor and an analog gauge to the same port, so you get live digital data and a classic needle readout at the same time.
Pressure gauge — a standalone analog gauge for machines where you just want a quick visual reference. No Bluetooth required.
KvdW Spiritello kit — a dedicated installation kit developed in collaboration with Roasttrip, available worldwide.
