A plug-and-play Raspberry Pi device that plays the call to prayer on the speakers people already own, set up in minutes from a phone, with a companion iOS app.

01

The challenge

  • The end users are not technical
  • Households use many speaker brands and protocols
  • Prayer times depend on location and calculation method
  • The device had to run unattended for months
02

What we delivered

  • Setup wizard through the device’s own WiFi hotspot and captive portal
  • Speaker support for Sonos, Samsung, Chromecast and DLNA/UPnP
  • Daily prayer times from the Aladhan API with 14 calculation methods
  • Mobile-first web dashboard and REST API
  • Native iOS companion app in SwiftUI
  • systemd services, a status LED and install scripts for reliable unattended operation
03

How we delivered

We built a Python service on Raspberry Pi with a web dashboard and REST API, managed by systemd. The SwiftUI app uses the same API, and we designed the whole setup flow around a single QR code on the device sticker.
