Acaia X La Marzocco Connected Scale – Espresso Scale for Linea Mini R

Acaia X La Marzocco Connected Scale – Brew-by-Weight for the Linea Mini

The paddle moves forward, the scale tares and starts the timer. At the target weight the Linea Mini stops the shot by itself. No glancing at the display, no button to press at the right moment.

The Connected Scale was developed jointly by Acaia and La Marzocco. It runs La Marzocco-specific firmware and is set up via the La Marzocco Home app. A prediction algorithm accounts for the drips that still fall into the cup after the stop. What counts is the weight in the cup, not the reading on the display at the moment of the stop.

What the Connected Scale does

Brew-by-weight

The scale stops the shot at the set target weight. A prediction algorithm estimates the flow and ends the shot so that the drips that follow are accounted for. This works on the Linea Mini and the Linea Mini R.

Grind-by-weight

With the La Marzocco Pico and Swan grinders, grinding stops at the set weight. No more weighing by hand afterwards.

Integration with the Coffee Station

The scale syncs with the La Marzocco app and the Coffee Station and shows the weight in real time throughout grinding and brewing.

Two doses in the La Marzocco Home app

In the app you store up to two target doses; alternatively there is a free-flow mode, for both brew-by-weight and grind-by-weight.

Auto-tare and timer

As soon as the paddle is moved, the scale tares automatically and starts the timer.

You need a machine that is online and runs current firmware (v1.0rc7 or newer). Depending on the year of manufacture, older Linea Minis need a Gateway or IoT kit installed by a technician. The Connected Scale does not work with the Linea Micra or the GS3.

The details in everyday use

Resistant to interference

Scale and machine ignore unusual readings during the shot, for example when a cup is put down or the scale is touched.

Water-resistant

The housing is designed for liquid spilled at the machine.

Fast, stable measurement

Readability is 0.1 g, and the timer is built in.

Battery and housing

The battery charges via USB-C, and the housing is made of aluminium.

We brew espresso by weight, not by time. We grind fine, start at 14.5 grams and work our way up from there, usually to 17 grams, at a ratio below 1:2. No two shots are the same, because beans, humidity and your own day change. The scale does the measuring, taste decides. Our opinion is one of many.

At a glance

Who it is made for

For everyone with a Linea Mini or Linea Mini R who wants brew-by-weight built into the machine workflow. The Acaia X ships ready for the La Marzocco system; no additional licence is needed.

If you already own an Acaia Lunar with USB-C (serial number from AL008): since March 2026 there is a paid upgrade to the same Connected Scale functions, purchased via the Acaia Updater app. The Lunar comes in several colours and also works with other machines. You will find both in the Acaia Collection.

For everyone looking for a precise espresso scale without machine integration: the scales in the Normcore Collection are compact, accurate and reliable. We explain the difference in the Acaia vs. Normcore comparison. Which machine and grinder suit you is narrowed down by our advice tool.

As the official Swiss importer of Acaia, we deliver throughout Switzerland and to Liechtenstein in 2–4 working days, with Click & Collect in Bern and Zürich. Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes. Drop us a quick line at [email protected] before your visit, and we will check whether the product you have in mind is currently there. You can test espresso machines and grinders side by side in the comparison workshop in the showroom, an option, not a requirement.
