Viter: a Bluetooth lifeline for old Prana ventilators
An Android app that locally controls Prana 150, 200G, and 200C ventilation units over Bluetooth, without an account or internet connection.
Field notes
The app communicates directly with compatible Prana units over Bluetooth and keeps a local list of discovered installations, each with a custom name and its last reported activity. Its interface reflects quirks of the underlying hardware rather than hiding them: speed changes proceed one step at a time, the nine sleep durations remain uneven, and intake and exhaust motors retain separate values. The published build is version 0.1.0 and must be installed manually on Android 8.0 or newer.
