Postbox

Postbox is the companion app for your LineSpotting mailbox sensor.

Connect with the sensor code from your kit, then see when your mailbox was opened — with timestamps, battery estimate, and a simple activity history.

What you get
• Mail-arrival status ("You have mail" when recently opened)
• Timestamped activity log from your LoRa sensor
• Battery level estimate from sensor voltage
• Pull-to-refresh and background checks every few minutes
• Phone alerts when a new mailbox opening is detected
• DEMO mode — enter DEMO on the login screen and a demo device will appear

Requirements
• A Postbox LoRa sensor kit from LineSpotting (sensor code required)
• Notification permission for mail alerts

Privacy
The app reads your sensor feed to show mailbox events. No ads. No data sold.
