View and send messages using the on-screen keyboard or predefined quick replies. The keyboard supports placeholders that insert live sensor data — `{time}` and `{loc}` are always available; additional placeholders (`{temp}`, `{hum}`, `{pres}`, `{batt}`, `{alt}`, `{lux}`, `{co2}`) appear automatically for sensors that are connected and returning data.
Press Enter on a message to open it in fullscreen. Navigate between messages with left (newer) and right (older).
Hold Enter on a message or channel to open a context menu: change per-channel notification settings (mute, follow global, or force-on) and per-channel melody override (follow global, Melody 1, or Melody 2), or mark messages as read.
A dedicated clock page on the home screen shows the current time and date, synchronized from GPS or via Bluetooth. Timezone offset is applied from Settings.
Up to three configurable data fields are displayed below the clock. Available fields: battery voltage, temperature, humidity, pressure, GPS coordinates, altitude, luminosity, CO₂, contact count, and total unread message count.
### Nearby Nodes
Browse nodes that have recently advertised on the mesh. Filter by category (Favourites, All, Companion, Repeater, Room, Sensor). Select a node to see its coordinates, distance, bearing with cardinal direction, type, and last-heard time.
Use **Send my advert** (hold Enter → context menu) to broadcast your position and prompt nearby nodes to respond with theirs.
Periodically broadcasts a 0-hop advert with your GPS position so nearby nodes can track your location automatically. Configurable interval: off / 1 min / 2 min / 5 min / 10 min / 30 min / 1 h.
A blinking **A** indicator appears in the status bar while Auto-Advert is active.
A step sequencer for composing custom notification melodies stored on the device. Two independent melody slots are available — **Melody 1** and **Melody 2** — switchable from within the editor. Each melody supports up to 32 notes with adjustable pitch (C–B + pause), octave (4–7), duration (whole / half / quarter / eighth), and BPM (60 / 90 / 120 / 150 / 180). Playback preview is available directly from the editor.
Melodies can be assigned as notification sounds per message type (DM / channel) in Settings, and individually overridden per channel or per contact from the message screen context menu.
