Old-fashioned coffee machines mainly refer to those coffee machines that cannot quantify and visualize each operation step in the process of producing coffee.

In fact, this kind of coffee machine is not only a household coffee machine, but also most commercial coffee machines do not have data quantification. Function, it is difficult to ensure the stability of production and the consistency of operation to a certain extent.

If everyone chooses a higher-value coffee machine in order to upgrade their equipment, although this is a solution, not all users can have such conditions.

So a startup from New Zealand has created a retrofit kit called Flow Coffee Telemetry that turns an old espresso machine into a smart system.

It's a three-part hardware and software suite that plugs into any traditional volumetric coffee machine's flow sensor to measure the speed and volume of each brew.

What Flow Coffee provides is the visualization of your coffee making process to ensure that every cup of coffee served will satisfy your customers and achieve your desired brew ratio.

The entire system consists of three parts: mobile devices, real-time meters, and analytics dashboards.

This mobile device, which looks a lot like a router, is a small internet-connected device that integrates with your coffee machine. Can be easily integrated with most volumetric coffee machines.

Real-time meters are displays that capture and analyze coffee machine data in real-time, providing baristas with instant feedback on compliance with preset recipes.

Such visualization also assists in many training environments, and can provide more accurate training data to baristas, allowing baristas to understand what preset operations should be followed.

The Analytics Dashboard is a web-based dashboard that provides visibility into the performance of each site. The whole operation needs to be realized through the WiFi link, so it needs the support of the network environment.

A web-based platform, a globally accessible dashboard, stores every data for analysis.

Connecting to a specific app via WIFI, the data is displayed in real time in a digital meter, with a flashing red signal when the barista might be off target and a green signal when the coffee is within the target flow.

The barista meter also shows when a cup of coffee is, and alerts for when grind settings may need to be adjusted. A cloud-based analytics dashboard then lets coffee shop owners and managers review performance results in a variety of graphical displays.

If you're the operator of a chain of cafes, the system can also see how the entire network is performing, and drill down to any specific location for further insight into how each branch is performing.

This enables viewers to assess and take action on the sites that need their help most, giving you the ability to diagnose remotely.

After five years from initial design to application, the Flow Coffee system has been trialled by multiple multi-store coffee companies across Australia, and earlier this year entered the US and Canada markets.

Close communication is currently underway with some coffee equipment manufacturers regarding the expansion of the system.

However, their technological innovation has not stopped, and they have been researching the virtual gravity measurement function, the purpose is not only to realize the data in the "cup", but also to monitor the coffee powder dose level.
