Know before you buy
The system is designed for machines with E61 group heads (M6 thread) or those using G1/8" threads. It is specifically tested for compatibility with the Flair 58 and the Cafelat Robot.
Yes, the app integrates with specific smart scales to capture weight data, including Acaia, Decent, and Skale2 models. You will need one of these compatible scales to track flow rate and ratio in real-time.
The transducer is programmed to automatically trigger the recording process once it detects a pressure of 0.8 bar. This ensures your data capture begins exactly when the pre-infusion or extraction starts.
Yes, the kit includes an analog pressure gauge that provides a live visual readout regardless of your app connection. This dual-feedback setup allows you to monitor your pressure manually while the digital system logs the data.
No, the stainless steel portafilter is not dishwasher safe. We recommend cleaning it by hand with warm water and a mild detergent to maintain the finish and integrity of the components.
The splitter choice depends on the physical layout and space constraints of your specific espresso machine. Choose the option that best allows the transducer and analog gauge to fit comfortably within your machine's existing plumbing.
