Set up and read out a coolant controller, without internet

A Flutter app for the Will-Fill coolant controller: a wizard to configure new devices, every log file with its history, and graphs that show drops in the measured values. Over the device’s own WiFi, without internet.

App Store screenshots of the Will-Fill app: device info, a list of logs and offline support

Will-Fill, from DIERICKX tools in Rotselaar, makes a premium coolant controller: a device on the coolant tank of metalworking and CNC machines that measures, fills, conditions and reports on the metalworking fluid by itself.

The challenge

The logs of a Will-Fill were synced through the cloud. Without a connection, the only way to read them was over SSH, which is not practical on a shop floor. DIERICKX tools wanted easy configuration and offline support, and came to impaktfull through a developer who recommended us for cross-platform development.

What we built

impaktfull created the mobile Flutter app for the Will-Fill products, for iOS and Android. It brings all reporting functions of the Will-Fill to a phone or tablet. The app connects directly to the WiFi network of the device, so it needs no internet connection and works in sensitive environments.

  • Configure a new device through a full wizard
  • Read all log files from the device in the app, and keep the history
  • Inspect the logs in graphs, to spot drops in every measured value
  • Full offline support

Who it is for

Will-Fill is a niche product, and the app is made for exactly those customers. For them it is very valuable: they read out a device on the spot, without the cloud or SSH. Will-Fill’s installers use the wizard to set up new devices.

Today

impaktfull still maintains the full project.
