  3. Devices on the same network (router/Wi-Fi) are discovered automatically. Selecting a device fills in its name and ID; rename it if needed and click Add Device. A device on a different network is added by entering its 16-character Device ID manually. Find the Device ID in the tray icon → About (Windows/macOS) or with systemctl status grablo (Linux).

Running

Once connected, the RUN/STOP buttons appear at the top. Clicking RUN sends all project settings to the device and starts the logic. The device then runs independently, so the browser can be closed.

Caution Logic does not run just by being created. You must click RUN for execution to start on the controller.
