Lucca Atom 75: Grinder Not Connecting to WiFi & App Not Working

Troubleshooting the LUCCA Atom 75 espresso grinder.


If your Lucca Atom 75 is not connecting to your WiFi:

  • The access point (WiFi router) is too far from the grinder. Move your grinder closer to your router, reposition your access point, or install a range extender or a second access point closer to your Lucca Atom 75.
  • Your WiFi network could be on the 5GHz band. The LUCCA Atom 75 can only connect to access points operating on the 2.4GHz band. Most WiFi access points working at 5GHz also make a network available at 2.4GHz, but the network name and password may differ. Consult the label or documentation of your WiFi access point to find your default 2.4GHz network name and password.


Before powering on the grinder, plug it into a grounded 120v outlet. Then, flip the main power switch on the lower rear right side of the grinder body.

After a welcome message, a list of available WiFi network SSIDs will be displayed. After selecting one, you will be prompted to enter the password for that WiFi network. If you do not see your home or business WiFi network SSID displayed on the list: tap and drag your finger on the touchscreen to scroll through the list.

  • Ensure that you are using the TrueGrind AI app

After connecting to WiFi, you will be prompted to install the TrueGrind AI mobile app, create a user account, and then register your grinder to your account by entering the unique Grinder ID into the TrueGrind AI mobile app.
