Main Menu
The main menu is the root of the Air Lite's USB-C configuration interface. All other menus are reached from here. It appears automatically after the unit boots, once a serial connection is established in Tera Term (or another terminal emulator).

Nothing in the terminal? Press Esc — the service menu will appear. Esc is also the "back one step" key in every sub-menu, so you can bail out of any submenu without committing changes.
From here
- ·Polling interval menu — how often the unit reports sensor values to the cloud.
- ·Firmware update menu — apply a firmware update over USB-C.
- ·System settings menu — initial serial configuration parameters.
- ·Modbus settings menu — address, baud rate, and device name.
- ·Reset menu — reboot the unit.
