Valet Phone-to-Zone — Home Intercom System

A home intercom system. The system consists of two apps: one for the house audio controller device, powered by Raspberry Pi, and the other is a remote caller app, installed on a mobile device, either iOS or Android. The Raspberry Pi with the app constantly running is connected to the home audio system, while the mobile app is always at the user’s hands. Using a smartphone, a user can make calls to set home zones (living room, patio, bedroom, etc.).

The user opens the app, clicks Connect to the patio, the app sends a request to the home-based device, the device in it’s turn sends a DTMF signal through the audio connector to the audio system, and the latter recognizes the signal and connects the user to the patio.

Available both for iOS and Android. Raspberry Pi app is NodeJS-based. The app uses Quickblox cloud backend platform.
